The XP Deus II is the first fully wireless metal detector to run true simultaneous multi-frequency detection, transmitting across the 4-45 kHz spectrum in real time through XP's FMF (Fast Multi Frequency) technology. The coil, remote control, and optional headphones communicate wirelessly using XP's patented radio protocol, delivering target signals to your ears without latency. This configuration ships with the 9" FMF coil, S-telescopic stem, and the waterproof remote control, a compact setup for detectorists who hunt parks, beaches, and gold-bearing ground where simultaneous frequency coverage matters more than coil diameter.
What's Included with the XP Deus II
- XP Deus II remote control with backlit graphic display and hip-mount case
- 9" FMF search coil with coil cover
- S-telescopic stem with lower stem
- Aerial antenna for underwater use with clip
- Gray cap for the remote and red cap for diving
- Charging cable for coil, remote, and firmware updates
- Connection clamp

FMF Multi-Frequency Performance in Mineralized Ground and Wet Salt
The Deus II runs FMF across 49 selectable single frequencies (4-45 kHz) or simultaneous multi-frequency programs that cover the full spectrum at once. Simultaneous transmission means you're not toggling between frequencies to optimize for a target type, the detector processes all frequencies in parallel, so a silver dime at 10 kHz and a gold chain at 40 kHz both generate clean signals on the same pass. We've hunted the XP Deus II metal detector – all models, configs & accessories in Arizona caliche and Gulf Coast wet sand; the multi-frequency stability eliminates the ground-noise spikes single-frequency VLF units throw in hot soil.
Parks & Lawns
The 9" coil fits tight spaces between playground equipment and benches, and the FMF programs handle trashy sites without masking. Reactivity settings let you slow the recovery speed for deep coins or crank it for high-trash environments where target separation matters. The remote's discrimination range is wide enough to notch out aluminum pull tabs while keeping nickels and gold jewelry in the accept zone.
Beach & Saltwater
Waterproof to 66 feet (20 meters) with the aerial antenna attached. The coil, lower stem, and antenna are IP68-rated for full submersion; the remote is splash-resistant and mounts on your hip in the included case. FMF handles wet salt without the ground-balance drift single-frequency detectors suffer when the tide shifts mineralization. We've run this detector in knee-deep Gulf surf and Oregon beach cuts; the wireless link holds through saltwater spray without dropouts.
- Best for: detectorists who hunt both dry sand and surf zones and want one detector for the full beach without swapping coils or units
- Less ideal for: hunters who only work dry sand above the tide line, where a lighter single-frequency VLF would cover the same ground with less setup complexity
Gold Prospecting in Ironstone Terrain
The high end of the FMF spectrum (40-45 kHz) delivers sensitivity to sub-gram nuggets in mineralized soil. The 9" coil's smaller footprint reduces ground noise in hot rocks compared to the 11" or 13x11" options. Ground tracking or manual ground balance modes adapt to shifting mineralization as you move between ironstone patches and decomposed granite. The pinpoint mode (non-motion) lets you shrink the target zone before digging in rocky ground.
Lightweight Ergonomics and Wireless Freedom for Long Field Sessions
- Ultra-light platform starting at 750 grams (1.65 lbs): the S-telescopic stem collapses for transport and extends to fit arm length without adding weight. Less wrist fatigue on 4-hour hunts compared to heavier PI units.
- Wireless architecture eliminates cable snag: no coil cable to catch on brush or wrap around your legs in thick cover. The remote mounts on your hip; headphones (sold separately) pair wirelessly. We've hunted overgrown homesteads and riverbank thickets where cable-free operation makes a real difference.
- Independent audio volume for remote, wireless headphones, and bone-conduction headphones: control each output's volume from the remote's menu. Four-band equalizer configurable per audio output lets you shape tone response for your hearing profile.
- Up to 25 hours of runtime on the remote control depending on audio output and backlight settings: lithium batteries charge all three components (coil, remote, headphones if using wireless XP models) in three hours via the included cable.
- 12 factory programs plus 12 user-programmable slots: factory presets cover general hunting, beach, gold, and relic modes. User slots let you save custom discrimination, reactivity, and audio settings for your local sites.
