Fast Multi-Frequency (FMF) is XP's simultaneous multi-frequency transmission system, operating from 4-45 kHz at the same time in a single sweep. Low frequencies in the range provide depth on deep silver coins and large relics, while high frequencies deliver sensitivity on modern clad and small jewelry targets. This simultaneous approach eliminates the need to switch frequencies mid-hunt and stabilizes target signals in conductive saltwater environments and mineralized ground where single-frequency detectors often chatter or lose depth. The DEUS II's FMF technology is distinct from frequency-switching systems that cycle through frequencies sequentially rather than transmitting them all at once.
