The Garrett AT MAX excels at coin shooting in parks, schoolyards, and old homesites where depth and target separation matter. The 13.6 kHz frequency strikes a useful balance between coin sensitivity and tolerance for trash, and Pro Audio gives us proportional volume and pitch shifts that make a faint silver dime feel different from a junk signal at depth. The backlit screen stays visible during late-evening park hunts, and the 44 iron discrimination segments let us skip bottle caps and foil before we cut a plug. For detectorists comparing dedicated coin machines, our guide to the best metal detectors for coins covers the AT MAX alongside multi-frequency options.
