Garrett Ace 400 Review


The Garrett Ace 400 should be considered the bigger brother to the 150, 250 and 350. It’s very similar with a few more features that you shouldn’t expect on the previous models.

This is the detector I’m currently using, read below why I’m recommending this over anything else.

The great feature about the 400 is the Iron Audio option, this helps the detector define the difference between iron and other metals. I will go into more detail about how that can be used below.

I have a personal connection whilst reviewing this model, I actually own and use this on almost a daily basis. This is my personal choice from any of the other models.

Although this is targeted more to the intermediate detectorist’s out there, I feel confident that if I was to go back I would have just gone for this straight away, the extra power and functionality isn’t confusing it’s helpful.

Key Features Of The Garrett Ace 400

  • Garrett Ace 400New Iron Audio – This allows users to accurately find out which metal it is they have found, this can be especially useful when searching for particular things such as bottle caps or coins.
  • New Digital Target ID: 0 to 99 scale offers target information
  • New higher frequency (10 kHz) provides better sensitivity on low and medium-conductivity targets (i.e. gold, lead)
  • New Adjustable Frequency to help eliminate interference
  • New Camlocks for better stem stability
  • New Includes Pulse-Width Modulation audio: sharper, more responsive audio
  • 8.5″ x 11″ PROformance™ submersible DD search coil offers excellent coverage, depth
  • Enhanced Iron Resolution: twice the iron resolution of an ACE 250, to help separate good targets from adjacent junk iron
  • Includes Electronic Pinpointing: precisely locates targets and speeds recovery
  • Notch Discrimination: Modify discrimination patterns based on what you are seeking.
  • Five Search Modes (plus Pinpoint)
  • Eight (8) Sensitivity/Depth adjustments
  • Coin Depth Indicator determines target depth
  • Expanded Target ID legend: includes indication of U.S. coin denominations

Features Explained:

New Iron Audio:

This is my personal favourite feature of this model, a big reason why I’m still using it today. It took some getting used to, sometimes it would give me a false reading, but it was more my not understanding of how it works. For example, a rusted fence would give a reading on a normal detector, however with the iron audio you can make sure the settings are allowing for such things, which is a big time saver.

If you are searching for iron or not you can turn it on or off depending on your goals. Below you will find a video explaining the iron audio function, turn your speakers down as it can be quite loud!


Digital Target ID:

This will help you differentiate between less and more conductive metals ie silver for example. It gives you a number from 1 – 99 on the LCD screen (Which you can see below), 1, for example, might be a rusted nail or something which has lost its conductivity, and a 99 could be silver. It’s not quite as simple as that, but that’s the most simple way to explain it that I could find.

Higher Frequency:

Not only does this come with a higher frequency (10kHz) but you are also able to adjust it. I personally like to use a lower frequency, but that’s more as I’m less and less willing to dig down deeper, however, if you’re struggling to find anything you would turn it up.

When you turn it up sometimes you can get interference, it’s just the detector finding too much, or finding things too far away. This is why I personally run it on 5-8kHz but that is just my preference.

New Camlocks:

These are just locks that essentially make the machine more stable, making it easier to use. All of Garretts models will soon have these.

PROformance™ submersible DD search coil:

From a design standpoint alone, you can see the difference between this and the 150, and 250 models. They’ve designed it so not only is it more accurate but also submersible. This makes it ideal if you are looking to do some detecting in shallow streams, it is still not ideal for underwater detecting, we have a whole section specifically for those.

I’ve personally used it in a couple of instances, my friend managed to drop her necklace into a garden pond, which it was perfect for that as it was only about 12 inches deep.

Pros Of The Ace 400:

  1. Simplicity – Although we recommend this machine for somebody that has been detecting for a while to really get the most use out of all the function, it still remains simple to use for anybody. With all Garrett models, there are clearly marked buttons which are easy to understand.
  2. Sensitivity – The 10kHz frequency delivers a great response, it is very accurate so you can be sure you are not wasting time digging in the wrong location. Along with its depth detector, you can weigh up the time spent digging.
  3. Bang for buck – The 400 offers a great value, out powering the 150, 250 and 350 from Garrett whilst keeping a similar price range. Especially with the kits available for this model, you can get some great deals out there. I will post the best at the bottom.
  4. Guarantee – Garrett is a company that very much stand by their products, it is still run by the same family that started it and are a pleasure to deal with. I personally had a couple of problems outside of my guarantee and they were more than willing to help. Great customer service!
  5. Weight – Coming in at 5.8 pounds it’s easy to manoeuvre and carry for long sessions.

Cons Of The Ace 400:

  1. The only con I can think of is as it’s not as popular it’s harder to get hold of, but it’s not really.

What Makes It Different From Other Detectors

The 400 comes with the Iron audio setting that is something that comes specifically with this Garrett model, it isn’t something that is standard with all metal detectors. What this allows you to do is distinguish between certain metals from another, for example, if you’re trying to find coins as opposed to trash. It’s ideal for anybody at any level, although this is aimed at the intermediate’s this can also be used by any beginner who is willing to read the instructions.

This model comes with the enhanced iron resolution, this is exclusive to the 400 and will help you to separate any junk that is located near your target. It’s quite common to get false readings when you’re out detecting, this can be from less experienced people not using the detector properly, or more likely if you’ve read my guide, some junk. If you are having problems where you keep digging up nothing, perhaps you’re in an area where junk is common. This would be the perfect detector in that situation.

This comes with a higher frequency than the 350 coming in at 10kHz, this is to be expected. Not only the name gives it away but it is slightly more expensive than the 250 and 350. The best thing about the 400’s frequency is it is adjustable, you’re no longer walking around detecting fillings in everybody’s mouths (I exaggerate of course), you can turn it down or up depending on what you’re looking for, if you’re looking for smaller items a higher frequency will have to be used.

I’ve really struggled to think of any cons of this product, it’s a well balanced, full metal detecting kit. I advise anybody who is considering buying one to go ahead. It’s a very sturdy product that comes with very little flaws as far as I could find.

Final Thoughts

I really enjoyed having a go on the 400, it was light, easy to use and gave me a lot of information. Sometimes for me personally it gave me a little too much information, I’m very much at the stage where I just find anything and dig it up, I’m sure for somebody more experienced it would be absolutely fantastic. That being said after getting used to it I have found it very useful, however, you certainly need more patience to get used to the software compared to most other beginner/ intermediate detector. Which is a good thing, it allows you more room to grow into this piece of kit.

I would recommend it absolutely, I have yet to see any negative review on this particular model, which makes me wonder why it isn’t as popular as the other models. It seems to me that this is a middle ranged detector. More advanced than a 250, but not quite at the level of the ATX or the Fisher F2.

I will be using it more and more as I move on from my basic detector, hopefully, it will improve my skill at the same time, I’m confident it will do.

Best Underwater Metal Detectors In 2018


Before you start even looking to buy a underwater metal detector, you need t to decide upon a few features first. There are a few things you need to ensure before you go diving underwater, first, you need to get the right kit for the task at hand. There are of course a few obvious things you need but let’s start with the biggest first, what is the best underwater metal detector for you?

Obviously, if you want to take your detector underwater it needs to be one thing above everything else, waterproof. We’ve gone ahead and reviewed the best underwater metal detectors below, after that we can go over what other equipment you need to get going!

Underwater Metal Detectors Compared

Garrett AT Pro

Garrett AT ProMost of the detectors that make this list will cost somewhere around the $1,000 mark, however the main reason that the AT Pro is my number one choice is the price. You are looking to spend almost half of that, a lot of people that I’ve previously helped with underwater detecting actually owned the AT Pro before due to its strength at detecting on land also.

Submersible to 10ft it can handle most places any hobbyist would want to go, if you’re looking to go deep sea diving you will, however, have to find an alternative. This detector is also able to survive in fresh and salt water, we all know what effect salt water has on electronics normally however not here.

Whilst only able to support 10ft that is more than enough for most of the readers of this website, if you are a bit more adventurous check out the other models below, there are some perfect examples of deep sea detecting down there.

Garrett AT Pro Metal Detector
  • Pro Mode Audio feature
  • High-Res Iron Discrimination
  • Digital Target ID
  • Can be used in water up to 10-foot depth

Minelab Excalibur II

Something for the more adventurous of us out there, this model can go all the way to 200ft depth, a bit more than I’d personally like to try. This model has an adjustable frequency, it comes with a BBS multiple frequency upgrades, ranging from 1.5kHz – 25.5kHz which makes it perfect for finding something no matter the surface.

Also fitted with RCB, what this does is amplifies the weak sounding detection and amplifies it through the coil ensure you’re not missing out on any potential finds. Which let’s be honest, if you’re 200ft down you don’t want to miss out on anything!

For safety this Excalibur has a Hi-Vis paintwork, this is to ensure that when you go down as a party, nobody gets lost. Which is terrifying and also exciting at the same time.

Minelab Excalibur II (Two) 1000 Underwater Metal Detector
  • New, longer lasting nickel metal hydride battery pack
  • New High Visibility (Hi-Vis) fluorescent bodywork
  • New Slimline Lighter weight coil for improved balance - easier to maneuver in all conditions
  • New Improved signal response
  • New Enhanced performance in salt water

Tesoro Tiger Shark Underwater Metal Detector

The Tesoro also comes with a terrifying 200ft depth range, which will satisfy even the most adventurous among us. This particular model comes with a specialty in finding gold, which is why this is the most popular for the gold searchers you see on TV.

What I liked particularly about this model is the ease of adjustment, at 200ft down you can imagine having a complicated detector is far from ideal, what Tesoro have done is really made a simple yet very powerful piece of kit that is perfect for anybody looking to dive.

To cut down on the breakables it has been hardwired at 12.5kHz, however, it does have 4 controls to fine tune your detecting experience.

White’s Surfmaster DF Water Metal Detector

This model comes with a 100ft depth range, whilst less than others on this list it certainly makes up for it elsewhere. Fitted with near neutral buoyancy coil which makes diving that much easier, you can imagine you don’t want to be fighting to keep your detector afloat and at the same time, you don’t want it to plummet.

It’s 12” Duel Field search coil is specifically designed to be sensitive to gold, yet it will still pick up other metals in the ground, you’re able to adjust this on the go.

A common problem with underwater detecting is the picking up of black sand and other trash targets, the adjustable pulse delay does a great job of reducing this whilst underwater. It carries on from Whites very high standards.

White's Surfmaster DF Water Metal Detector - 800-0323
  • Adjustable Pulse Delay
  • Completely Waterproof- depth of 100ft
  • Enhanced Sensitivity to Gold
  • Quick Target Recovery
  • Model Number: 800-0323

Garrett Infinium Water Proof Metal Detector

Another detector with 200ft depth housing, this is Garrett’s main detector for underwater/diving. We all know how much I like Garrett and this is no different. Built to offer the user as much information as possible whilst underwater.

It is very sensitive and adjustable, you can select the high-low tone to target gold, and the low-high would help you find silver, copper, and iron. Popular among the gold hunters the Infinium is starting to make a name for itself.

Garrett Infinium Metal Detector WATERPROOF!
  • All Metal Deepseeking Mode
  • Audio Threshold, Adjustable
  • Frequency, Adjustable

Guide To Buying Underwater Metal Detectors

Before you buy any detector you need to consider the need, what exactly are you planning on doing with it. This is especially important when looking for a waterproof detector, are you planning on diving down over 100ft? Or perhaps testing it out on a river bed, doing this will save you money and also get you a better detector for your needs.

What are you looking for? Most (Not all) of the people who’re taking their detector underwater are looking for gold, then you should consider getting one that is specialized at finding gold underwater, the same goes for silver or any other find.

When it comes to deep detecting you want in essence the simplest piece of kit possible with you, it’s dark and murky and having something complicated is only going to hinder you. Also the simpler the kit the less likely it is to break, whilst all the detectors above come with substantial warranty it’s something to consider.

Brands You Can Trust

There is always a risk when going out of the recommended brands that what you’re getting isn’t quality, this is especially important when dealing with something that claims to be waterproof. It is quite common for “waterproof” products to just be covered in a sealant which until broken makes it waterproof, doing this you could make any product waterproof for a given amount of time.

The detectors above are all designed to be waterproof and last. These are not once and done products, they are all subject to extensive testing. Before making a purchase make sure to check that the warranty length and terms are something you are happy with.

Additional Extras

Aside from the actual diving gear as let’s be honest, that is not our expertise. You should consider everything you need. Does the detector come with waterproof headphones for example?

Excluding the AT Pro which is designed for rivers all the others on this list would need these but do they come with them (They do, but if you’re considering something else)?

Garrett Ace 250 Metal Detector Review


My first ever metal detecting trip was with the Garrett Ace 250, I was actually allowed to borrow it from a friend. I’ve been hooked ever since I placed my order within the week of trying it and I still use it today 6 years later. It really is a great piece of kit. It’s not my main detector but sometimes I still bring it out just because it’s so light and user-friendly.

For the beginner treasure hunter looking to find gold, jewellery, relics and more while treasure hunting; the Garrett 250 metal detector is a good entry-level choice.

It’s budget friendly, fairly straightforward and easy to use. Today, we’ll be reviewing and examining the features that have made it one of the top-selling metal detectors out there. And what you should expect should you decide to get one.

Garrett Ace 250 Breakdown:

The Garrett Ace 250 is engineered, manufactured and assembled by the largest metal detection company in the U.S.A; Garrett Metal Detectors. It is an affordable detector and is mainly advertised for beginners and home utility.

It is lightweight (weighs less than three pounds), and very comfortable for you to use. And while it is targeted at people who are new to the hobby, it also has enough features to keep experienced treasure hunters happy. Some of these features include; adjustable sensitivity and depth settings, pinpointing, custom notch discrimination, 6.5×9″ ACE coil, etc!

Bear in mind; learning to use this detector effectively will take some time and practice because it isn’t an ordinary entry-level metal detector as it comes loaded with features normally reserved for mid-entry level metal detectors.

Garrett Ace 250
Get This Deal Here.

Having highlighted the above, let’s now discuss the features.


The Ace 250 has a long list of features, I’ve gone ahead and summarized the most important below.

Push-button controls

The Garrett Ace 250 Metal Detector comes with 6 push-buttons; Power, Discrimination, Mode, Sensitivity, Pinpoint, and Elim (short for eliminating). The Power button is a simple one-touch operation and the machine powers up.

The Discrimination button is used in conjunction with the Elimination button and is used to eliminate specific items while out hunting. The sensitivity button increases or decreases the sensitivity of the machine, while the pinpoint button determines the exact location of a target.

The Mode button navigates through the modes, these modes are:

  • All metal: Detects all metals including Iron.
  • Jewelry: Ignores items such as bottle caps, and nails.
  • Custom: The custom settings can be programmed using the elimination and discrimination to select individual specifications.
  • Relics: Keeps good targets in the lower conductivity end, while eliminating trash targets

All the buttons are big and clearly labelled; making it easy when setting it up, but not so big as to crowd the feedback part of the display.

Large LCD display

It comes with a 10” simple LED display for easy functionality and sweeping accuracy. The display bears advanced sensitivity functions and an electronic pinpoint feature and is easier to read and interact with than a lot of the competition.

Garrett ace 250 Screen

The LED display features the following:

  • Target ID
  • Detecting mode
  • Coin Depth Indicator
  • Battery monitor

And just by looking at the screen, you can tell what is going on with minimal configuration required:

The graphics target ID appears at the top of the screen with easily identifiable hash marks that are ideal for quick glances.

The depth indicator appears to the right; numbered and providing permanent feedback about how deep (up to 8 inches down) a target is.

The display also has a standard battery indicator and not just the low battery warning that pops up with most other detectors.

Garrett Search coils

The Garrett ACE 250 comes with plenty of different compatible search coils; which are:

  • Standard Search coil
  • 5 x 9 Search Coil
  • 5 x 11 ACE DD Search Coil
  • 9 x 12 Search Coil
  • 5 x 8 DD submersible Search coil
  • 5 ACE Sniper Search Coil

Most beginners should find the 250’s standard coil adequate.

The search coil is able to fake out trash metals; it’s also waterproof for movement in shallow waters and is useful should the sensitivity settings be further increased.

Bear in mind; the control panel is not waterproof but you can purchase waterproof housing for this at a low cost.

Some Other Notable Features

Battery Life: The Garrett Ace 250 metal detector has up to 30 hours battery life. This ensures that you can be on the field for long hours without having to worry about low battery as is the case when using other metal detectors.

This is good for a number of reasons, aside from the obvious but it is able to run 30 hours from 4 x AA batteries, I can’t even get a torch to run an hour on that! There are detectors out there that will have built-in batteries that can be recharged. It’s up to you whether you take that as a positive, but it’s a big reason why Garrett is able to offer this machine at such a low price.

Fourth Bell Tone: In addition to the three basic audio beeps that sound when the Ace 250 is moved over targets; the Garrett Ace 250 Metal Detector has a fourth

bell tone that allows coin shooters collect coins. And while this may not be useful if you’re relic hunting; coin shooters will welcome hearing that additional confirmation.

Target ID: A very useful visual guide on how far down what you’re detecting is beneath you. As you can see from looking at the LCD screen above, there is a bar that shows the sensitivity, the more full the bar gets the closer/more detection there is.

If it is something large or close it will give a higher reading than not. This is a good way to decide whether something is too deep for you to dig it up or not.

What Is It Actually Like?

Sometimes when reading reviews online I get a good list of the features, the pros, and cons but you don’t find out what the product is actually like? Or is it just me?

Having used this detector for over 4 years I think I’ve got a good grasp of what this machine is like when it’s actually being used.

Watch the video below, it’s an instructional video of how to get the best out of the model.

So How Much Does It Cost?

The all important question, I mean it could be the best machine in the world but if it costs too much what is the point? Well, you’ll be glad to know the Ace 250 comes in around $250, a bargain when you think of the technology involved with this machine.

There are packages available that range from $250-$350, which depending on the use you’re getting out of it will determine what package is good for you, to look at the whole range click here to go through.

Warranty & Support

The Garrett machine comes with a 2-year warranty. And while this short two-year limited warranty may not be on the high side, they adequately make up for it with their outstanding customer support, online instructional videos, and well-detailed FAQs.

250 Screen coverWhat else you should know

You may want to note that other people have mentioned how the Ace 250 can become a little temperamental in highly mineralized conditions, giving off an increased amount of false signals.

Also, there is no volume control on the actual detector; however, you can purchase a good pair of headphones that have a built-in volume control.


The Garrett Ace 250 is a good metal detector; it’s easy to use and has lots must-have features which, once mastered, will allow you to find a lot of coins, jewellery and other cool relics of the past. It is a treasure magnet and simply one of the best metal detectors for beginners that you can find!

Metal Detecting Advice

Best Metal Detecting Locations


The opportunities for locating treasures using your metal detector are endless and limited only by your imagination.

The key element is using it in the right places! Because, while there tons of places to find coins, gold, relics, and buried or hidden treasures; some sites are more productive than others. Hence, you need to know the best type of places to go detecting.

And when you’re going detecting, one simple thing you want to keep in mind is that; to locate treasure, you must go where people have been, where they lived, where they worked and played(from way back to present times).

And the reason is simple…

People lose coins, gold, relics all the time. Many valuable treasures are also buried and, for unknown and sometimes circumstantial reasons, they are never retrieved. All these present countless opportunities for you! So, you want to go to these places and be the one to find the spoils!

To make your search more effective, you should determine what you are searching for and then conduct a little bit of research to identify the most promising and productive treasure hunting sites(based on where people have been, where they lived, where they worked and played) to detect. This little research would help streamline your efforts; and you’ll be able to ascertain where to focus your hunt on, depending on what you are searching for.

In this article, I’ve created a list of the best metal detecting locations that are generally more productive for treasure hunting:

A Crowded Beach:

The beach has consistently proven to be one of the best metal detecting locations due to numerous human activities that have taken place over the years.

So, that favorite beach of yours can be a real gold mine.

Timing is of the essence however, as the best time to go there is immediately the crowd has left for the day or going in the morning before everyone shows up. And the good thing is, digging on the beach sand is simple and easy, especially with a beach metal detecting sand scoop.

And if you’re using a metal detector like the Minelab E-Trac Metal Detector; which can be used underwater or in shallow water, you can schedule your visit for when there is a low tide, so as to locate items that sometimes get lodged near rocks as the tide disappears. However, if you are detecting in or near the water, ensure to play safe by knowing your tide tables, as you don’t want to get caught in an incoming tide.

Also metal detecting after a storm portends a lot of opportunity, as there is the high likelihood that objects which had been stuck underwater are now brought to the shore.

beach metal detecting


Another place that has consistently proven to be one of the best metal detecting locations; especially when it comes to coin-shooting are churches. They hold the oldest coins as they are often times the oldest buildings in the community.

Every Sunday (from time immemorial), churches have been hosts to a large number of congregants who gather weekly.

This constant visits and activities over such long periods of time means an opportunity to locate treasures that people have lost overtime; making the church a very viable place for metal detecting.

Deserted and Abandoned Towns

There’s a caveat here: most deserted and abandoned towns have been hunted to death with not much left to find. The key to effectively exploiting deserted or abandoned towns is finding the ones NOT well documented.

Once you can do that, deserted and abandoned towns can be one of the best places to go metal detecting. They hold hoards of treasure (especially old mining or transportation towns). With the trading activities that used to happen, it is possible to find old coins. And not only would you find old coins but other items of a bygone era.

As stated earlier, the key is to find the ones NOT well documented. And to do this, you’ve got to ditch Google maps and instead use other methods like talking to locals, the elderly or driving around yourself.

Bear in mind however, that might have been turned into protected areas by the government with some restrictions. So, be careful not to trespass.

Parks & Campgrounds

Parks & campgrounds in older areas are usually productive places to detect. These places have been utilized for various activities over the past years. And like most highly productive areas for metal detecting have had tons of people throng to and from them, hence giving you a chance to locate valuables that may have been lost as a result.

Beware of local authorities policies in some places though. You want to make sure you follow their laid down rules or you risk confiscation of the metal detector.


Older school yards, especially activity areas such as baseball, soccer, football fields, etc can be ‘HOT’ areas for metal detecting.  Be sure to check not only the action spots but also around the field as the audience can leave behind plenty valuables as well.

Also, modern school grounds are a great place to find modern coins. The key is to go when class is not in session and look for activity centers or large areas where students like to sit on the grass.

Bear in mind however, that permission is important. And if you leave gaping holes in any field, you will be asked to leave.

Your Backyard

If you live on a property that is older than 1965, then your backyard is a great place to metal detect. You have a chance to find some valuable US silver coins lost by previous owners.

Also, your backyard offers you an opportunity to practice, especially if you’re new to metal detecting.

There you have them; the best metal detecting locations. And while this list is by no means exhaustive; they give you a good head start on your metal detecting journey.

Don’t forget to record your finds so you know what areas are producing more than others.

How Does A Metal Detector Work?

Image4of PartII

Metal detector technology is a huge part of our lives as it provides millions of people around the world an opportunity to discover hidden treasures; while also ensuring safety in airports, office buildings, schools, government agencies, and prisons by helping to ensure no one brings weapons onto such premises.

So, you’ve probably been wondering… How exactly does this stuff work?

Well, the internal working of metal detectors is based on the science of electromagnetism. It works by using technology to harness the unique relationship that exists between electricity and magnetism.

In this article, I would be explaining in details the basic working principle of a metal detector and the technologies that make different types work.

Bear in mind that it’s not necessary to know how a metal detector works in order to use it. However, it’s quite possible that knowing how it works can help you use it more effectively in the future.

The Basic Working Principle of Metal Detectors

The basic working principles of metal detectors are based on electromagnetic induction.

Basic Controls of metal detectors

Metal detectors work by interacting with metallic elements on the ground through one or more inductor coils that are attached to them. They work by electromagnetic field transmission from the search coil attached into the ground. As a result of this electromagnetic transmission, any metal objects (targets) within the electromagnetic field range will then become energized and transmit an electromagnetic field of their own in return. The detector’s search coil then receives the re-transmitted field and alerts the user by producing a target response.

Most metal detectors are designed with a discrimination feature; which is the metal detector’s ability to identify underground targets based on its ferrous and/or conductive properties. This feature allows metal detectors discriminate between different types of targets and can be set to ignore unwanted targets.

Having had a basic understanding of how metal detectors work, let’s now talk about the technologies that power this principle.

The Technology

  • Very Low Frequency
  • Pulse Induction
  • Beat-Frequency Oscillation

Here’s a brief look at each of these technologies in detail to see how they work.

Very Low Frequency (VLF)

Very Low Frequency is the most popular metal detector technology in use today. And it employs the use of 2 distinct coils; namely the transmitter & receiver coil.

The transmitter coil is the outer coil loop. It contains a coil of wire through which electric current flows up and down (up to about 1000 times per second).

The electric current flowing up and down through this transmitter coil generates an electromagnetic field which interacts with any conductive substance it encounters and causes these substances to generate their own weak magnetic fields.

The receiver coil, on the other hand, is the inner coil that’s also made up of another wire coil. Again this wire coil works like an antenna to detect the frequencies of targets underground and amplify their signals.

To differentiate between different metals, the VFL relies on a phenomenon called “phase shifting”. Phase shift provides VLF-based metal detectors with a capability called discrimination; which is a metal detector’s ability to identify underground targets based on its ferrous and/or conductive properties.

And since the resistance and inductance in most metals vary, the amount of phase shift is examined by a VLF metal detector, using phase demodulates (which is a pair of electronic circuits), and compares it with the average for a particular type of metal. You then get notified with a visual indicator or audible tone indicating the range of metals the object is likely to be in.

PI Technology

PI Technology differs from Very Low Frequency (VLF), because it uses 1 coil as both a transmitter and receiver. Some, however, are known to use multiple coils (two or even three) working together at once.

Powerful pulses travel along the wire coil that creates small magnetic fields. When these run out, the polarity gets reversed by the magnetic fields then collapses to make an electric spike. In microseconds, the spike runs out after it generates another current to move through the search coil.

PI detectors are able to pick up metals buried far deeper than other metal detecting technologies.

Beat-Frequency Oscillation- BFO Technology

Beat-Frequency Oscillation (BFO) is the most basic form of metal detecting technology. In a BFO system, there are two coils of wire. The larger coil is put in the search head while the smaller one is placed inside the detector’s control box.

An oscillator connects each coil and generates thousands of pulses of current per second.

The coil generates radio waves as pulses travel through each coil. The radio wave is picked up within the control box by a tiny receiver and creates an audible series of tones depending on the difference between the frequencies.

When a metal object is passed over by the coil, the magnetic field caused by the current flowing through the coil generates a magnetic field around the object. The magnetic field of the object interferes with the radio wave frequency generated by the search-head coil.

As the frequency in the control box deviates from the frequency of the coil, the audible beats change in tone and duration.

The Beat-Frequency Oscillation, however, doesn’t offer the same degree of accuracy and control put forward by the other 2 technologies. And metal detectors that use the BFO technology are sold at a lower price because of its simple design.

Factors that can interfere with how a Metal Detector Works

The detection depth of a metal detector depends upon which of the above technology it employs and a number of environmental factors listed below…

  • Ground Mineralization
  • The Size of the Target
  • The Shape of the Target
  • The Orientation of the Target
  • The Material of the Target

So, there you have it. You now have a basic understanding of how your metal detector works.

Features: Here’s what you get

The Minelab E-Trac Metal Detector has the following features:

  1. Advanced Signal Processing Using Minelab Full Band Spectrum Technology

The E-Trac Metal Detector uses Minelab’s proprietary Full Band Spectrum technology that outperforms typical detection technologies, by transmitting broader range of frequencies between 1.5 KHz 71galnzyzul-_sl1200_– 100 KHz simultaneously. The wide range of frequencies transmission allows the operating system of the E-Trac Metal Detector to instantly analyze responses from the signals received from the coil and then interpret them to provide users with enhanced accuracy.

This technology results in a greater operational depth range, higher sensitivity over a wide range of targets, less electromagnetic source interference and more accurate target identification.

  1. QuickMask And SmartFind Technology

The E-Trac Metal Detector also features Minelab’s proprietary QuickMask and SmartFind technology. The SmartFind technology feature is a two-dimensional graphing display that graphically shows the user the ferrous properties as well as the conductivity of the metal found at the same time. This allows you to easily identify targets before digging.

The QuickMask feature on the other hand, allows you to instantly adjust the conductivity and ferrous rejection levels based on conductivity and ferrous

levels, allowing you to accept and reject based on these 2 indicators; thereby making your search much more effective.

  1. Lightweight Waterproof 11 Inch Double D Coil

The E-Trac Metal Detector features a lightweight and waterproof 11” Double D Coil. The lightweight and the waterproof feature of the coil make it possible for you to search a variety of challenging locations, such as the sea, river, beaches, etc; locations other detectors dare not thread.

And even in instances where some other detectors have claimed usability at these challenging locations, the result is not at par with the performance of the E-Trac Metal Detector, as hunters rarely find valuable targets at these locations, using other detectors.

However, E-TRAC delivers astounding results at these challenging locations.

  1. Four Preset Detecting Settings

The E-Trac Metal Detector features four preset detecting settings that’s usually the common types of detecting that experienced hunters do namely; Coins, High trash, Beach, and Relics!

Coins: For searching coins.

High trash: For searching in trashy areas.

Beach: For searching on beaches.

Relics: To search for valuable targets.

With these preset settings feature for the most common types of detecting; you can simply turn on the detector, choose a setting, and start hunting without spending any time on adjusting the settings. Amazing time saver!

It additionally features a Pin Point Mode that lets you pin point accurately your find and the size of it before you start digging down into the ground.

  1. Clear Resolution “72mm x 48mm ” LCD Display Panel

The E-Trac Metal Detector has a “72mm x 48mm” LCD Display Panel that provides clearer on-screen graphics and improved target identification.

The display is neat, with buttons nicely placed on the display to make it easier for you to access the menu and make adjustments easily; thereby making detecting with E-Trac much easier.

The display is backlit; meaning you can use the E-Trac Metal Detector late in the evenings and even at night.

  1. E-TRAC USB functionality

One prominent feature of the E-Trac Metal Detector is the USB functionality that allows you connect the detector to the computer for you to better manage settings, modes, as well as discrimination patterns and build a resource you can continually refer to.

The detector comes with a cable with which you can easily connect it to a PC or laptop.

This advanced feature is also designed to allow for quick configuration of the E-TRAC at the touch of a button to specific detecting areas and preferred targets; thereby allowing you spend little time, adjusting settings, but instead more time out in the field , detecting.

What Else You Should Know

You may want to know that the E-Trac Metal Detector is much better at finding silver than it is at finding gold. A number of users have reported that low quality gold has been mistaken for trash by the detector.

Also, the programming is a little different from what some more experienced users are familiar with. So, you may want to bear in mind that the learning curve can take some time, before getting used to. But once you get a hang of it. The money spent is well worth it.

Irrespective of the above however, the Minelab metal detector still comes highly recommended to those that want to explore further and increase their treasure finding capabilities.


The Minelab E-Trac Metal Detector is without a doubt, one of the best deals you can find in the market. It has set a significant technological advancement with all its features highlighted above and its quality performance. I highly recommend it for the experienced hunters who want to substantially improve their metal hunting experience.

Metal Detecting Advice

What Is The Best Metal Detector For Children?

So if you’ve ever done metal detecting around your children, your grandchildren or even just children from friends, they always want to have a go. This is great and I love getting children involved and they really enjoy it, in fact now when I see my grandchildren I hide money around the garden so when they find it they can keep it. Small tip, if you’re going to do that make sure they don’t need to go digging! It won’t leave the garden very nice and your wife might not like it, mine didn’t.

What are they key points you need to remember when looking for a child metal detector:

Size – This is the most important, depending on how old the children are will mean they need to have a detector that can be adjusted. If they are using one that is too big they will create an angle on the coil and will be detecting in front rather than underneath, which will mean the detector needs a bigger depth and will, of course, cost more money.

Weight – Sort of covered in the size of the detector, make sure to get something that isn’t too heavy, it will just make it more troublesome. My back starts to hurt if I’m carrying too much let alone a small child.

Simplicity – This is one of the only times I’m not looking for as many gizmos and gadgets as possible, normally I’m trying to get everything possible even though let’s face it, I don’t use most of it! You have to remember what they’re, and that is children. Keep things as simple as they possibly can be.

I don’t think many children are worried about which type of metal it is they’re finding, they just want to dig something up out of the ground! Side note: This will also save money!

Price – I don’t know about you, but my children and grandchildren haven’t had the longest attention spans, so I didn’t want to go spending a great deal of money on something they would rarely use. Luckily my grandchildren quite enjoy it when it’s nice, it’s something we can do together whilst we’re waiting for food to cook. Even still I wouldn’t want to spend too much on it.

With all that in mind the metal detector I would choose time and time again for any child is the bounty hunter metal detector.

Bounty hunter metal detectorIt really is good value, it does exactly what you need and it costs less than $100. It is the perfect present for any budding metal detector. With the above kit, you also headphones included, you can use any you like, even their own personal headphones.

Where can you take them?

When I first went out I went to parks, beaches anywhere I could to be honest. However taking a child out is rather risky, you don’t want to be digging big holes with them, or rather they don’t want to be. Like I mentioned earlier I found they enjoyed it the most when I planted change around the garden.

I hope you enjoy sharing your hobby with them, as always I hope you enjoyed reading my metal detecting blog.

Tips On How To Find More On Your Hunts

glastonburyeventMaybe Glastonbury in the UK is of limits, but you get the idea.

Whether you’re new to the game or an experienced detector sometimes we can go over and ignore the basics to metal detecting. Below I’m going to cover some tips on how to get the most from your hunts, if you’re experienced you can use this as a tune-up.

Perhaps you’ve got so used to going out on your own and it’s all natural, perhaps you’ve picked up some bad habits.

What should you take with you on every hunt:

  • Metal detector – OK well that was a little bit obvious!
  • Backpack / Something to carry your finds in
  • Small shovel – It doesn’t need to be too big as anything that requires considerable digging should usually be avoided anyway
  • Headphones – Depending on your surrounding’s it might be difficult to hear otherwise
  • Supplies – Well this depends on how long you intend to go for, are you well stocked?
  • Ideal clothing – Is it going to rain?
  • Underwater – Do you need a waterproof detector?

To me and probably most of you they all seem like must haves and how could you forget it? These things get forgotten more often than you’d think. I’ve personally forgotten to check the weather beforehand and been caught out in the rain, it happens more so now that I’m staying in the UK. I can’t wait to go home in a couple of months!

Where should you go?

The best places to go are areas of public interest, for example, beaches and parks are great especially for beginners. It’s unlikely you’re going to discover an ancient relic but you will find change, jewelry, watches (although usually worse for wear) and any other object that people carry with them a lot. I did actually find some car keys once, although I’m sure they had been there a long time as they were buried and covered in rust.

 Top places to go:

  • Parks
  • Beaches
  • Sidewalks
  • Walking paths
  • Event’s
Maybe Glastonbury in the UK is off limits, but you get the idea.
Maybe Glastonbury in the UK is off limits, but you get the idea.

These are my favorite places to go, anywhere where the footfall is high is always going to bring in good finds at a good rate. Sometimes you get some odd looks from people unsure what you’re doing but it can be a nice way to start up a conversation. I actually helped a woman look for her engagement ring once, she was very thankful as I’m sure her soon to be husband wouldn’t have appreciated that!


I don’t really have a name for it, so I’m just going to call it the low and slow method, it’s rather self-explanatory in that you need to scan as close to the ground as you can and slowly sweep side to side.

This the best way to get the most out of your searches, I’ve tried other approaches but I always feel like I’m potentially missing so much by accidentally not scanning the whole area.

This has to be the most common way of scanning, 90% of the people I come across are already adopting this method, the only problem for me if most of them scan too far away from the ground.

This all depends on you personally, your height, the length of the detector and your physical abilities. If perhaps you’re older with a bad back it’s going to be hard to crouch down with a smaller detector. I have a personal recommendation for the best detector to start with.

If physically possible, the best way to get the most detection is to keep the coil as close to the group as possible. Think about it if your detector has a limit of 12” wouldn’t you want that to be on the ground? You’re essentially wasting any depth that is above ground.


Hopefully, you found this useful, this is more catered to the beginners in the detecting world, you can refer to this as a check sheet every time you go out looking for objects.

Fisher Metal Detectors

Fisher F44 Review


Fisher are known for standing by all of their products, which is why I love reviewing their kit. I know that anybody who reads this will know they are going to be well looked after by Fisher, this product in particular comes with a 5 year warranty, there are not many manufactures that would be able to match that. fisher f44 detector

The F44 is ideally for an advanced beginner or an intermediate, somebody who has gone out metal detecting before. However if you are a beginner I would still consider this, you have a lot of room to grow into this and Fisher have gone to the effort of sending you a guide along with it. The guide will teach you the basics of detecting, a bit like my guide. I’m going to talk more about this later but there are no other detectors that I know of that will help you differentiate between gold and silver at this price point. For that usually you have to add another $200.

What are the key features of the F44?

  • Weatherproof – If you’ve been following me for awhile now you know I’m spending a lot of time out in the UK, the problem with that is the rain! This was a nice addition to an already strong detector. I don’t have to go inside when it rains anymore, I do usually but that’s just because I’m a wimp!
  • Manual ground balance – This is what help you differentiate between the different types of alloys such as silver or gold.
  • 5 Modes of operation – This allows you to specifically look for certain alloys and objects.
  • Beginners guidebook – This is a very nice touch which I think a lot of companies should introduce, not only do they give you a helpful manual on the actual workings of the detector. Fisher go beyond that and help you as a beginner find more stuff!
  • 5 year warranty – I can’t find any company that will match or beat this, truly how all companies should operate.

Pros of the F44:

We’ve gone over the key features, I’d now like to cover the pros in my personal opinion, not get the actual specifications of the product.

  • Weatherproof – I’ve already voiced my opinion on this however I really think it’s something I now expect from all detectors, but they don’t all deliver. Although it’s not submersible it allows for all weather detecting.
  • Weight – Only coming in at 4.8 pounds
  • Warranty – You really can’t go wrong with it
  • Comfort – Very comfortable, I used it for 4 hours without any problems at all




I’ve really enjoyed my time with this machine, like most Fisher products it does exactly what you want it to. I can’t find many faults but here’s what I did find.

  • Waterproof – It is weather proof however the product is not completely submersible, it would have just been nicer if Fisher had taken it to the next level and make it completely waterproof. The AT pro is waterproof so if you’re looking to do detecting in water I would recommend it.

Final thoughts on the F44

This model is really aimed at the beginner/intermediate market, which makes it perfect for my readers. I don’t get as many advanced hobbyists on this site, it mainly comes from the beginner/intermediate bracket to be honest.

The weatherproof element is great, not having to worry about it breaking if it rains or it gets splashed on. Nothing worth than spending $300 on something for it to break in the rain! You can’t go wrong if you’re just getting into this brilliant hobby, with a 5 year warranty it will last as long as you look after it.
