Garrett ACE 300 Metal Detector with 7x10 Coil

The Garrett ACE 300 is a single-frequency VLF metal detector built around an adjustable 8 kHz operating frequency, a 0 to 99 digital target ID, and four-segment iron discrimination that lets us notch out bottle caps and rusted nails while keeping nickels, small jewelry, and brass buttons in the audio. It sits in a sweet spot inside the Garrett ACE Series metal detectors lineup: more capable than the ACE 200, simpler and lighter than the AT or Apex platforms, and built around a 7 by 10 inch concentric search coil that pulls clean signals out of mineralized turf and worked-over coin sites. We sell the ACE 300 to detectorists who already know what they want from a midweight VLF and want to stop fighting their machine.

Adjustable 8 kHz VLF Performance in Parks & Mineralized Turf

Old Parks, Turf, and Town Greens

Mature park turf is where the ACE 300 shines. The 8 kHz frequency reads US silver coinage with stable target IDs in the high 70s through high 80s, and the concentric coil's cone-shaped detection field gives a tight, predictable footprint when we are working between tree roots and irrigation lines. Old picnic areas, demolished bandstands, and fenceline strips around historic greens are realistic targets. We have found that switching off Coins mode and dropping into Custom with one extra notch closed lets us pull deeper wheat cents past pulltab depth. Park hunters who want consistent target ID at depth without learning multi-frequency menus get a workable, repeatable setup here.

Old Homesites, Cellar Holes, and Relic Fields

The ACE 300 is not a relic-only machine, but on plowed fields and old homestead sites the Iron Check graphic and four-segment iron resolution earn their reputation. We watch the discrimination pattern while we sweep, and we dig anything with a non-iron pixel mixed in. Brass buttons, large copper, and broken silver come up readable on the scale, and the 7 by 10 inch concentric coil separates targets cleanly when iron trash is heavy. Relic hunters appreciate the adjustable frequency's ability to shift off interference from power lines and nearby detectors at club hunts without losing depth on common targets.

Freshwater Shorelines and Wet Grass

The 7 by 10 inch concentric coil is fully submersible, so we run the ACE 300 right up to lake edges, creek banks, and saturated turf after rain. The control housing itself is not waterproof, so we keep the housing dry above the splash line and rinse the coil at the end of the day. The detector is not engineered for saltwater or wet salt sand, where mineralization will overwhelm the fixed factory ground balance, and we steer customers to an AT-series machine when surf hunting is the goal.

Four-Segment Iron Discrimination & Digital Target ID for Clean Signals

• Adjustable 8 kHz operating frequency lets us shift off interference from power lines, club hunts, and nearby detectors without losing depth on common coin and jewelry targets.
• Four-segment iron discrimination, twice the resolution of the ACE 250, lets us notch out bottle caps and rusted nails while keeping nickels, small jewelry, and brass buttons in the audio.
• 0 to 99 digital target ID with a three-tone audio scheme gives us enough resolution to call quarters from copper pennies before the coil leaves the target.
• Eight sensitivity levels paired with an adjustable notch let us tune for hot dirt, EMI-heavy parks, and quieter relic ground without leaving the menu.
• Cam-lock stem and a 2.8 lb total weight let us swing the ACE 300 for several hours without the wrist fatigue that older ACE shafts caused.

Compare within the family

Detectorists cross-shopping the ACE lineup often weigh the 300 against the top-tier ACE 400 and the multi-frequency Apex to see where the feature set justifies the step-up cost.
