Overview
The Garrett ACE 400 is a made-in-USA VLF metal detector built for finding coins, relics and small jewelry across beaches, rivers and varied terrain. Its 10 kHz frequency boosts sensitivity to low- and medium-conductivity targets such as gold and lead, making it a strong all-round choice for hobbyists ready to move beyond an entry-level machine. The ACE 400 adds Iron Audio so you can hear discriminated iron and skip flat trash like bottle caps, plus a Frequency Adjust function that shifts the operating frequency slightly to eliminate interference from other detectors or power lines. It offers five search modes plus a dedicated pinpoint mode, a Digital Target ID from 0 to 99, eight sensitivity settings, electronic pinpointing, a coin-depth indicator and high-resolution iron discrimination. It ships with an 8.5″ x 11″ DD PROformance submersible search coil, coil cover, ClearSound headphones and a control-box cover-up, runs on four AA batteries and is backed by a 3-year Garrett warranty.

Frequently asked questions
Can the Garrett ACE 400 find gold?
Yes. Its 10 kHz frequency is well suited to low- and medium-conductivity targets, so it detects gold rings, coins and jewelry effectively, though it is a coin-and-relic VLF detector rather than a dedicated gold-nugget machine.
Is the ACE 400 waterproof?
The 8.5″ x 11″ DD search coil is submersible for wet grass, shallow water and the dry beach, but the control box is not waterproof and must stay above the water line.
What does Iron Audio do?
Iron Audio lets you hear discriminated iron targets that are normally silenced, helping you identify and avoid flat iron trash like bottle caps and washers before digging.
What powers the ACE 400 and what warranty does it carry?
It runs on four AA batteries and is covered by Garrett's 3-year manufacturer warranty.
