Garrett ACE 400 Review
The Garrett ACE 400 is built around 10 kHz single-frequency VLF. Its value depends on whether Iron Audio and DD coil matters more than fixed ground balance and non-submersible control box.
Bottom line
Useful entry relic machine, but compare modern SMF pricing
The Garrett ACE 400 is a rational choice for entry-level coin and relic hunters. Do not buy it merely for the brand or an isolated depth claim: its strongest reason to exist is Iron Audio and DD coil, while the principal compromise is fixed ground balance and non-submersible control box.

Analysis
What actually changes the buying decision
Iron Audio and DD coil is the feature that materially separates this detector from simpler options. It should solve a repeated hunting problem, not merely look attractive on a specification sheet.
fixed ground balance and non-submersible control box is not a minor footnote. Buyers whose normal sites expose that weakness should select a different architecture before spending on coils or accessories.
Usable depth changes with coil size, mineralization, target shape, orientation, moisture and settings. This review therefore avoids unsupported universal depth numbers.
Reasons to choose this route
- Iron Audio and DD coil
- Designed for entry-level coin and relic hunters
- waterproof coil only water protection specification
Reasons to choose something else
- fixed ground balance and non-submersible control box
- Exact bundles vary by retailer
- Performance still depends heavily on coil control and ground
