Garrett ACE 300 Key Features

VLF Technology

Produces an electromagnetic field that applies a continuous sinusoidal wave to the ground.

Mono Coil

Regardless of the need for more thorough overlapping, such coils can spor deeper targets.


Useful mode to save the target from damage when digging it out; also does not allow the detectorist to lose a small target in dirt.

Waterproof Coil

Nice feature that increases the range of potential locations and environments for detecting

Notch Discrimination

This feature allows to filter off certain types of metal you don’t want to spot. You can move the cursor to the left and to the right, and activate / deactivate pixels you want.

The Garrett Ace 300 is an excellent detector for beginners and even the more advanced users. This device offers an excellent potential detection depth (but depends much on the material being scanned), sturdy and hard wearing design (which ensures that your device stays functional even after a scrape or two), and very easy to assemble and operate (so even total newbies will be able to get up and running in no time at all). You get all these features, but the cost of the tool is absolutely on budget. So, take a deeper look at the features of the Garrett Ace 300 metal detector.

Garrett Ace 300 LogoThe Garrett metal detector is a really great tool. And thanks to the cutting edge technology, it is considered one of the most efficient metal detectors in the industry. It has many useful features, including one touch treasure hunting, five search modes, a continuous depth indicator, and pinpoint targeting. With pinpoint targeting, you have the ability to accurately determine the location of a specific target.

This feature works best when used in sand or gravel. In order for the pinpoint feature to function properly, you have to set the search coil to the loudest possible signal. Once there, push and hold the pinpoint button. You are now in pinpoint mode. Start sweeping the ground. Make sure the metal detector is not too close to the ground. Keep it at a consistent height while you sweep. Once the metal detector is right above the target, it will notify you. The target ID light will turn on and the LCD will show at least 5 bars.

Now let’s talk briefly about the detection modes. As it has already been stated before, the Garrett Ace 300 comes with 5 search modes: all metal, coins, relics, jewelry and custom. In custom mode, you are able to control the notch discrimination and target ID settings. All metal mode can detect all sorts of metals and can be used when searching for different types of targets. Jewelry mode will detect jewelry, coin mode will detect coins, and relic mode will detect things such as brass and lead.

Another great feature about this the Garrett Ace 300 is that it was created with your comfort in mind. You can adjust the shaft and armrest to a position that is comfortable for you. There is also a headphone jack so you can accurately distinguish the tones. This way you know if something is worth your time, or is just a piece of trash.

Once you find a treasure, please make sure you dig it out safely. You don’t want to damage the target before you retrieve it. The Garrett Ace 300 owner’s manual suggests you use the C-Cut method. This basically means you will use a knife to cut a “C” around the target. Pull up the dirt and extract the target. Once you have the target you will need to put the removed ground back in place.

Overall, the Garrett Ace 300 is a great metal detector. It is perfect for those who love to go out on the beach and search for those lost treasures.

Search Modes

Preset modes are handy for fast and accurate tuning of the metal detector, depending on the location and targets wanted.
