XP Deus II 13 x 11 inch FMF Waterproof Search Coil, Lower Rod, and Hardware

The XP Deus II 13 x 11 inch FMF coil runs the full 4 to 45 kHz spectrum as simultaneous multi-frequency programs or as one of 49 selectable single frequencies, giving Deus II owners a single coil that covers low-conductor micro-jewelry and high-conductor deep silver across mixed-target sites. Built for the Deus II platform, this elliptical FMF coil transmits multiple frequencies at once and recovers between targets fast enough to hold a stable signal in trashy ground that defeats single-frequency operation. Deus II owners hunting urban parks, old fairgrounds, and relic sites reach for the 13 x 11 inch footprint when they need wider ground coverage without sacrificing target separation.

Why Deus II Owners Reach for the 13 x 11 inch FMF Coil

• Wider sweep coverage reduces the number of passes needed to work a site, a measurable time advantage on large open fields and beach transects where the 9-inch and 11-inch coils require extra overlap.
• Full 4 to 45 kHz range on a single coil eliminates the need to swap hardware when moving from a silver-coin park hunt to a gold-jewelry beach session.
• Wireless design with coil-housed electronics and battery delivers up to 20 hours of runtime per charge, depending on the program and frequency selected.
• Waterproof to 20 meters (65 feet) supports full submersion for river wading, surf hunting, and shallow-water diving, well past what wading-rated coils handle.
• Elliptical geometry offers better maneuverability around obstacles and tighter target separation in iron-heavy sites compared to round coils of equivalent sweep width. For detectorists working multiple coil sizes, our metal detector search coils catalog covers DD, concentric, and monoloop options across platforms.

Wider Ground Coverage in Trashy Urban Parks

Old Fairgrounds and Schoolyards with Dense Iron

Urban sites with decades of bottle caps, pull tabs, and ferrous trash demand a coil that can separate a coin signal from adjacent iron without falsing on every swing. The 13 x 11 inch elliptical footprint covers more ground per pass than the 9-inch or 11-inch round coils while maintaining the target separation the Deus II platform is known for. Run one of the multi-frequency programs when you need wide spectral response across mixed targets, or lock to a single frequency for surgical work on a known target type. We've used this coil in parks where the 11-inch round coil required three overlapping passes to cover a grid square; the elliptical geometry reduced that to two passes with no loss in depth or discrimination resolution. Understanding the technologies behind modern detectors helps explain why simultaneous multi-frequency operation holds a stable signal in conditions that defeat single-frequency coils.

Beach Hunting from Dry Sand to Surf Zone

Saltwater beaches present two challenges: wet sand mineralization that destabilizes single-frequency detectors, and the sheer area that needs coverage during a falling tide window. The FMF coil's simultaneous multi-frequency transmission compensates for ground phase shift in real time, and the 13 x 11 inch sweep width lets you work a tidal cut in fewer passes. The 20-meter waterproof rating supports full submersion for surf-zone hunting and shallow-water diving, and the wireless design eliminates the cable-snagging problem that wired coils face in wave action. Coil weight is 1.25 pounds, light enough for extended swings without arm fatigue during a four-hour low-tide session.
