Overview

The Garrett ACE 400i is the flagship of the ACE series, a feature-rich VLF metal detector designed to help you dig more good targets and less junk. It is recommended for coin, jewelry and relic hunting plus dry-beach and freshwater use, making it a capable choice for enthusiasts who want advanced tools without a steep learning curve. The ACE 400i runs at an adjustable 10 kHz for greater sensitivity to low- and medium-conductivity targets such as gold and lead, and the frequency can be shifted to eliminate interference. Key features include Iron Audio, a Digital Target ID from 0 to 99, enhanced iron resolution (three times that of the ACE 250), notch discrimination, electronic pinpointing, five search modes plus pinpoint and eight sensitivity/depth levels. It comes with a submersible 8.5″ x 11″ DD PROformance search coil, Pulse-Width Modulation audio for sharper response, ClearSound headphones, a coil cover and a control-box cover-up, runs on four AA batteries and is backed by a 3-year Garrett warranty.

Frequently asked questions

How is the ACE 400i different from the ACE 250?
The ACE 400i adds Iron Audio, a numeric Digital Target ID (0–99), three times the iron resolution, an adjustable 10 kHz frequency, frequency shift and Pulse-Width Modulation audio, plus a larger 8.5″ x 11″ DD coil for better sensitivity to gold and deeper coverage.
Can the ACE 400i find gold?
Yes. Its adjustable 10 kHz frequency gives strong sensitivity to low- and medium-conductivity targets, so it detects gold rings, coins and jewelry well, though it is a coin-and-relic VLF detector rather than a dedicated gold-nugget machine.
Is the ACE 400i 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 powers the ACE 400i and what warranty does it carry?
It runs on four AA batteries and is covered by Garrett's 3-year manufacturer warranty.
