If you are looking for a lightweight detector for your apprentice or yourself (if you are new to relics, coins, or jewelry hunting), then this Garrett Ace 300 could be exactly what you need.

With its 5 search modes and a host of other features only seen in the top-rated and the more expensive varieties of metal detectors, it doesn’t come as a surprise that this metal detector is wildly popular in the world of metal detectors.

Looking at its numbering system, the ACE 300 is one of the metal detector models released by Garrett as part of their ACE series/ product range. The ACE range of metal detectors, specifically ACE 300, offers many more features than the ones offered by the ACE 15, even though it’s cheaper than the ACE 350 series. Its features and design make this the ideal choice for starter detectors.

But just how good is this detector? Does it live up to its hype and reputation?

In the search for the best metal detector, you will come across a variety of metal detectors, each claiming to be better than the previous one you looked at. Whether you an experienced metal detector or a beginner, the options will leave you confused. With that in mind, we’ve looked at all the elements and features of this metal detector in a bid to ensure that you have all the facts about this detector and decide if it’s better than its competitors or not.

Below is a Comprehensive Review of the Garrett ACE 300

Simple Design and Ease of Use

Before you buy a metal detector or any other gadget, you need to ensure that you are spending your money on a device that can be used immediately you unbox it or soon after. Its design should allow for ease of use, and it should last or hold well in case of use in a tough environment.

Looking at its functional design, the Garrett ACE 300 is an excellent fit for beginners or entry-level metal detectors who don’t have much experience in VLF detectors. Its 6.5kHz frequency operation makes this detector an excellent choice for coin hunting. It also meets the acceptable requirements for jewelry and relic hunting. Note, however, that its frequency is lower than that of ACE 350 or AT Pro. The primary disadvantage of the low operating frequency is that you cannot use it in gold prospecting.

If you are buying a metal detector from Garrett’s ACE series, you should know beforehand that the detectors in this range cannot handle soil that has a high degree of mineralization.

But don’t let this stop you from buying this ACE 300.


Like the other Garrett metal detectors, this detector boasts an intuitive design, it’s easy to use, and it has an excellent design that doesn’t compromise on features.

As mentioned above, it’s lightweight. At 2.7lbs, this detector is easy to use. Its design also features a unique 3-piece design that sports an elbow rest to keep your arms comfortable as you use the detector. Its stem is quite adjustable with a total length that ranges from 42’ to 51’.

It also comes with simple controls that are easy to use. The control panel doesn’t feel fiddly

Regarding powering, this detector is powered by 4 AA batteries. Though the batteries work well, you will note that you could end up saving a lot more money by investing in the rechargeable cells. But if you don’t want to deal with the reduced runtime, you might have to stick with the batteries. New batteries have a run time of 20 to 25 hours.

The other factor you should be aware of is that it lacks a voice control function, which means that if you intend to use headphones, they should have a voice control function.

How long will it last?

The unfortunate truth is that this Garrett ACE 300 looks rather cheap. Although this isn’t a huge issue when it comes to the functionality of the metal detector for minimal use, the truth is the detector will not last forever.

Now that you have a general idea about what to expect let’s look at some of the top features of this Garrett ACE 300.

Acceptance/ Rejection Discrimination

Like the rest of the best (real) metal detectors, the discrimination setting is an important setting that enhances the ease of use of the detector.

In the case of the Garrett ACE 300, there are 12 Target ID segments that you could use to enhance your notch discrimination. What this means is that you get to filter the objects detected, depending on your environment. This filter offers fine control over the items you signal or ignore.

Being a standard feature, discrimination ignores the features you don’t want to find. The best part is that you can adjust the discrimination upward or downward, using the plus or the minus buttons. You should, however, keep in mind that when you ignore the trash signals detected, you might end up ignoring your real targets accidentally.

Target ID Cursor

The target ID cursor is the most important feature of any metal detector. While this ACE 300 lacks the numerical Target ID, it comes with a 12-segment geographical target display instead. This Target ID might not be as accurate as the numerical target ID system, but it provides an overall idea of the items you detect before you start digging. On the bright side, the labels are rather large, meaning that beginners get a grasp of what they want faster than they would using the 0-99 numerical target ID.

In addition to the large label 12-segment geographical targeting system, this metal detector also comes with three levels of audio tones. These tones mean that you don’t have to look at the control panel at all times.

So, if the metal detected is iron, the tone will be lower than the tone produced following the detection of any other metal or trash. Using the all-metal mode, it’s easier to detect real objects from trash objects.

Search Modes

Even though this is an ideal metal detector for beginners, it does the job well with its 5 search modes. These search modes include the pre-set discrimination patterns that allow you to make adjustments for different settings.

These setting modes include:

  1. All-metal mode – it detects all the metals on the ground, ignoring the discrimination setting. So, if you are unsure of the materials, you are searching for, or if you’d like to dig out for everything to avoid the real target, then this All-Metal mode is your ideal fit. Alternatively, you could use it of your signal is inconsistent.
  2. Coins – This mode ignores the iron trash, as well as pull tabs and everything else on the ground, allowing you to find the coins you are looking for. If you are coin hunting in a park, this setting will work well for you.
  3. Jewelry – this setting is ideal for the detection of necklaces, rings, watches, and bracelets. Under this setting, the detector ignores bottlecaps and nails.
  4. Relics – the relics mode allows for the detection of lead and brass objects, as it ignores the smaller iron items.
  5. Custom – the custom mode/ setting allows the creation of unique patterns of discrimination. You can also use this setting to save your preferred settings for discriminations. The custom function is better fitted for use by advanced users looking to improve their hunting skills,

Waterproof Design of Searchcoil

A metal detector is incomplete without the best quality search coil. In this case, the best search coil features a waterproof design. The Garrett ACE 300 comes with a 6.5” x 9” PROformance search coil with an elliptical shape. This coil offers a focused pattern of detection compared to the circular alternatives, enhancing the detector’s accuracy. The elliptical coil design also provides extra depth and level of separation for the DD coil.

Thanks to its waterproof design, the detector is submersible in water, although you need to be careful not to submerge the entire metal detector since its control box is not waterproof.

If you need a coil with some more power, you might have to upgrade to the ACE 350 featuring a standard DD coil. But be ready to pay more.

Pinpointing Function

In addition to the 5 search settings, this Garrett ACE 300 comes with a pinpointer search mode/ function that enhances the accuracy of the target location. The pinpointer is quite easy to use such that once it’s activated, you’ll have to keep an ear out for the strongest signals to determine/ know when your coil’s center is right above the target. Using the top cursor, you will have the cursor’s signal strength, meaning that you will find your target just as fast.


If there’s a feature that takes the cup home for us, it has to be the controls panel of this Garrett ACE 300. For the price, this control panel is very impressive with color-contrast cursors that are easy to see. The featured control functions include:

Modes –

The button for the mode settings will cycle through different preset modes. Once you choose a mode, you get to adjust the settings manually. Unfortunately, these settings will not be saved to ‘memory’ once you turn off the machine.


To use the discrimination function mentioned above, use the button labeled DISCRIM. You can then use this button to select the target ID or the ELIM button to toggle the readings on and off.


this detector has a sensitivity ranging from 1 and 8”. With a high sensitivity recorded, it means that the target is at a greater depth. Note, however, that if the settings for sensitivity are too high, you could be easily overwhelmed by the readings, not to mention the false readings.

The pinpoint function is also on the control as are functions for battery levels and the coin depth indicator. Note that the coin depth indicator is essential for hunting coins thanks to the 8” accuracy.

Overall Performance

Its lightweight design is an important feature, and when it comes to treasure hunting, you always want to make sure that you have a metal detector you can carry around for hours without worrying about its weight or how uncomfortable it feels. This Garrett ACE 300 offers the best of both worlds, in terms of its low weight and the ergonomic design.

It comes with a factory preset ground balance function, which is easily adjusted, depending on the level of ground mineralization.

The other reason why this is one of the good metal detectors, especially for beginners, is because it has simple controls on an easily maneuverable control panel. The adjustment modes are all easy to use.

Its elliptical coil further enhances the precision of the metal detector while the sensitivity setting reduces the false positives.

Unfortunately, the ACE series is not ideal for use in the toughest conditions or areas with extreme mineralization. Its sensitivity is, however, impressive for the money you pay.

Yes. Despite its relatively low price, it’s packed with essential features necessary for the detection and hunting of coins, relics, and jewelry, among other metallic items on the ground.

The interesting bit is that this metal detector is super affordable and you wouldn’t expect to get that much value from a metal detector in its price range, but what can we say – this detector offers great value. You’d have to spend a lot more money for the same features if you were buying a different brand.
