XP Deus II 9" Round FMF Waterproof Search Coil with Lower Pole and Hardware

The XP Deus II 9-inch FMF coil is a wireless multi-frequency search coil built for the Deus II metal detector, covering 4 to 45 kHz as simultaneous multi-frequency programs or as one of 49 selectable single frequencies. Deus II owners hunting urban parks, schoolyards, and saltwater beaches reach for the 9-inch footprint when they need target separation in trashy ground and full-day swing comfort without arm fatigue. The FMF family is the only coil lineup compatible with the Deus II platform, making this the upgrade and replacement path for any Deus II owner.

Why Deus II Owners Reach for the 9" FMF Coil

• The full frequency range handles low-conductor micro-jewelry and high-conductor deep silver on a single coil, eliminating hardware swaps when moving from a gold-jewelry beach session to a silver-coin park hunt.
• Wireless electronics and battery housed inside the coil deliver runtime up to 20 hours per charge, depending on the program and frequency selected.
• Waterproof to 20 meters supports full submersion for river wading and surf hunting, well past what standard wading coils handle.
• The 9-inch diameter balances ground coverage with maneuverability in tight spaces, and the 0.76-pound weight reduces arm fatigue during full-day hunts.
• Adding a second FMF coil doubles your platform: pair one to your remote and one to wireless headphones, and you have two ready configurations on a single Deus II metal detector.

Tighter Target Separation in Trashy Park Sites

Sifting Urban Parks and Schoolyards with the XP Deus 2 Platform

The 9-inch FMF coil recovers between targets fast enough to hold a stable signal in iron-heavy ground that defeats single-frequency operation. Run one of the multi-frequency programs when you need wide spectral response across mixed targets in a single sweep, or lock to one frequency for surgical work on a known target type. Deus II owners working urban parks with decades of bottle caps, pull tabs, and foil debris use the 9-inch footprint to thread between trash and isolate keeper signals. The wireless coil design eliminates cable snag points when working tight spaces around benches and playground equipment.

Saltwater Beach and Surf Hunting

The 20-meter submersion rating supports full-depth surf hunting and river wading. Wireless transmission eliminates cable snag points. Deus II owners hunting saltwater beaches run the wireless coil in multi-frequency mode to stabilize ground response on wet sand, where single-frequency detectors often false on salt mineralization. The 9-inch diameter maneuvers between beach umbrellas and towel clusters during peak season, and the 0.76-pound weight keeps swing fatigue low during full-tide transects.
