Proportional Pro Audio on the Garrett AT Pro reads target depth and edges through tone strength, so faint and deep targets no longer sound identical to shallow ones. In PRO mode, you hear subtle changes in a target's response that help you judge conductivity, size, shape, and depth before you dig. A deep silver coin returns a softer, rolling tone while a shallow nail gives a short, stuttering iron grunt. STD mode delivers full-strength binary tones for detectorists who prefer a clean, consistent signal, but PRO mode opens the nuances that let experienced hunters separate good targets from trash by ear.
