The Garrett AT Gold runs at a high 18 kHz operating frequency, with a manual frequency-shift adjustment across four channels to step away from environmental EMI. That specific frequency tuning is what delivers exceptional small-gold sensitivity, explaining why the AT Gold reads sub-gram nuggets that lower-frequency general-purpose machines pass completely over. While it excels at sniffing out low-conductivity metals in hot ground, it belongs to our broader category of versatile very low frequency (VLF) metal detectors built for precision separation.
