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

The 9-inch FMF coil is compatible with all XP Deus II metal detector configurations, including the Deus II RC (with remote control), Deus II WS6 (with headphone control), and Deus II Master (full system). The FMF coil family is the only coil lineup built for the Deus II platform. The detector does not support legacy XP coils from the original Deus or third-party coils, so the FMF series is the upgrade and replacement path for any Deus II owner. Pair the coil to your remote or wireless headphones using the Deus II pairing menu.

The 9-inch FMF coil handles saltwater beach hunting with the same 20-meter waterproof rating and multi-frequency ground-balancing capability as the larger FMF coils. The smaller footprint gives tighter target separation in trashy wet-sand zones where bottle caps and foil cluster near the towel line, and the lighter weight reduces arm fatigue during long surf-wading sessions. The 11-inch and 13 x 11-inch coils cover more ground per sweep on open beach transects, but the 9-inch excels in crowded swim areas and around jetty rocks where maneuverability matters. All three coils run the same frequency range and multi-frequency programs, so the choice depends on site density and swing endurance rather than detection capability.

A: The XP Deus II 13 x 11 inch FMF coil provides an impressive field runtime, though actual battery life varies depending on the specific program and frequency you select. The wireless design houses both the electronics and the battery seamlessly within the coil structure, removing the hassle of external wires. When it's time to power up, the coil recharges via a dedicated charging cable that securely connects directly to the coil's integrated charging port. You can easily track your remaining battery life in real time right from your Deus II remote control or wireless headphone display.

The 9-inch FMF coil's battery delivers up to 20 hours of runtime per charge, depending on the program and frequency you select. Multi-frequency programs and higher single frequencies consume more power than lower single frequencies. The coil recharges using the XP charging cable included with your Deus II detector. The wireless coil design integrates the battery inside the coil housing, and the 20-hour runtime supports full-day hunting sessions across most programs and frequency selections without needing a mid-hunt recharge.

The coil cover is included with the 9-inch FMF coil and ships pre-installed or packed separately depending on inventory batch. XP supplies the cover with every FMF coil as part of the standard package. Replace the cover when it shows through-wear or edge tears. XP sells replacement covers separately, and our team stocks them for round coil configurations. The included cover is designed to fit the 9-inch FMF coil housing and installs with a friction fit over the coil's bottom surface.

A: Adjusting your settings is handled entirely through your main Deus II user interface—either via your remote control or the WS6 wireless headphones. This advanced FMF coil supports 49 selectable single frequencies ranging from 4 to 45 kHz alongside the default factory multi-frequency programs. Simply navigate using the frequency menu on your control unit to cycle through your options. Most detectorists prefer to utilize the simultaneous multi-frequency programs for broad target scanning, only locking down to a single frequency when attempting to surgically isolate a known target type or bypass localized electromagnetic interference.

The 9-inch FMF coil is built exclusively for the XP Deus II platform and does not work with the original XP Deus, XP Deus Lite, or XP ORX detectors. If you own an original Deus or ORX, you need X35 or HF coils for those platforms. The Deus II is a separate system with its own coil ecosystem, and cross-platform compatibility is not supported by XP. The FMF coil family runs the 4 to 45 kHz frequency range and wireless protocol specific to the Deus II, making it incompatible with earlier XP detector models.

The 9-inch FMF coil carries a five-year parts and labor warranty from XP Metal Detectors, covering manufacturing defects in materials and workmanship. Serious Detecting is an authorized XP dealer, so warranty service routes through us to XP's U.S. service center. Keep your purchase receipt and register the coil on XP's website to activate the warranty. For warranty questions or service requests, contact our customer care team before shipping the coil. XP designs the FMF coil lineup for long-term durability and backs each coil with the five-year warranty period.
