Garrett ACE 300 Metal Detector with All-Purpose Carry Bag

The Garrett ACE 300 bundle combines the ACE 300 detector and its 7 x 10 inch PROformance concentric searchcoil with a Garrett All-Purpose Carry Bag. We recommend the ACE 300 to beginners and occasional detectorists searching parks, yards and relatively mild ground. Garrett's ACE 300 runs at 8 kHz, and its searchcoil is submersible, while the control housing is not.

What the add-ons in this Garrett ACE 300 bundle do

Garrett All-Purpose Carry Bag: durable, reinforced polyester protects the ACE 300 against wear and tear, and the 50-inch length takes any current Garrett detector without removing the searchcoil. Two zippered pockets organize accessories, and shoulder straps and carry handles give you a choice of how to carry it to the site. See our Garrett carry bags and pouches.

About the Garrett ACE 300

What we like about the Garrett ACE 300 is its straightforward operation: numeric target identification and useful discrimination, plus five search modes and electronic pinpointing, without overwhelming a beginner. The controls are easy to understand, so a first-time owner can concentrate on target responses and search technique. We would choose the ACE 300 for affordable, straightforward recreational metal detecting.

Garrett ACE 300 search modes and key settings

• Five search modes plus Pinpoint: Zero-Disc, Jewelry, Custom, Relics and Coins. Garrett designed Coins mode to find coins and eliminate common trash such as iron, foil and pull tabs, and the manual warns that medium-sized jewelry may be missed with that discrimination pattern. Jewelry mode is designed to find rings, bracelets, watches and necklaces while ignoring most iron trash, and Relics mode eliminates small iron pieces while detecting good targets in the lower conductivity range.
• Digital Target ID from 0 to 99: with three audio tone ID levels and a depth indicator for a coin-sized target. Target ID can vary widely with a target's size and thickness, and mineralized soils can cause Target ID errors, especially on small targets.
• Iron Check and discrimination: four iron discrimination segments within a 12-pixel discrimination bar, an adjustable notch and Graphic Target Analyzing, which shows a target's conductivity alongside the discrimination pattern. To keep iron from masking a good target next to it, Garrett's manual recommends using just enough discrimination to barely reject the iron trash, so the coin and the nail are detected together.
• 8 kHz with frequency adjust: four minor adjustments (F1 to F4) help reduce interference from power lines or another detector. The ACE 300 remains an 8 kHz detector; the adjustment manages interference and does not select different operating frequencies for different targets.
• Eight sensitivity levels: Garrett's manual recommends higher sensitivity for very small or very deep targets, and lower sensitivity when the detector behaves erratically because of heavy trash, highly mineralized soil, electrical interference or other detectors nearby.

Water use with the Garrett ACE 300

The ACE 300 is not a fully waterproof detector. Garrett's manual says the searchcoil is submersible, but the control housing and connectors are not, and it advises protecting the control housing from heavy mist, rain and blowing surf. On a freshwater beach you can work the shoreline and put the coil in shallow water while the control housing stays dry. For someone regularly searching wet saltwater beaches, we would recommend the Garrett ACE Apex, the Garrett Vortex VX7 or the Garrett Vortex VX9; see also our beach metal detectors.

Where the Garrett ACE 300 works well, and where it does not

Picture a teenager searching the backyard for lost coins: that is typical ACE 300 ground. We would start in Coins mode at a moderate sensitivity and teach them to investigate each repeatable signal from different directions before digging. It runs at 8 kHz with a 7 x 10 inch concentric coil and adjusts automatically for ground minerals, without the ground balance adjustments of Garrett's AT series. Garrett's searchcoil guidance says a concentric coil is the most susceptible to interference from ground minerals, and a Double-D coil significantly outperforms it over mineralized ground. For trashy areas, Garrett's manual suggests the Super Sniper or a 5 x 8 inch DD searchcoil. See our beginner and intermediate metal detectors.

Moving up to the Garrett ACE 400

The Garrett ACE 400 runs at 10 kHz, adds Iron Audio and uses a larger 8.5 x 11 inch DD coil. For someone who wants Iron Audio, we would point to the ACE 400; for affordable, straightforward recreational detecting, the ACE 300 remains our pick.

Garrett ACE 300 battery and build

Garrett lists the ACE 300 at 2.8 lbs (1.27 kg), with camlocks for stem stability and a stem that adjusts from 42 to 51 inches (1.06 to 1.29 m). Four AA batteries run 20 to 40 hours depending on battery type and quality; NiMH rechargeables may give a shorter life per charge. A battery condition indicator shows the charge, and the headphone jack takes any headphones with a 1/4 inch plug.

One mistake to avoid with the Garrett ACE 300

Assuming that a high numerical target ID guarantees a valuable coin is the mistake we would warn about. The number reports the target's conductivity, not its value.
