The Garrett AT Pro runs a single 15 kHz operating frequency, a sweet spot for coin, relic, and small gold jewelry sensitivity without sacrificing depth on silver. The 15 kHz frequency pairs with two audio personalities: STD mode delivers full-strength binary tones for new detectorists, while PRO mode opens proportional audio and tone roll that give you subtle target nuances. While it excels at general hunting, it belongs to our broader class of very low frequency (VLF) metal detectors designed for versatile land and shallow water applications.
