The Garrett ACE 400 sits in Garrett's lineup alongside Garrett ACE Apex, Garrett AT Max, Garrett AT Pro, Garrett Axiom. It uses VLF (Very Low Frequency) — a single transmitted frequency, typically 3–81 kHz. VLF machines discriminate well — telling iron from silver by phase response — and are light and affordable. Their weakness is mineralized ground and wet salt sand, which read as false targets.

The Garrett ACE 400 is a strong pick for coins detecting, but no machine is universal. Check the waterproof line before any water use, confirm the weight against your stamina, and remember that ground conditions affect real-world performance more than any spec number.
