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.\u003c\/p\u003e\n\n\u003ch2\u003eWhat's Included with the XP Deus II 13 x 11 inch FMF Coil\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eXP Deus II 13 x 11 inch FMF waterproof search coil\u003c\/li\u003e\n\u003cli\u003eCoil cover\u003c\/li\u003e\n\u003cli\u003eLower pole\u003c\/li\u003e\n\u003cli\u003eHardware kit\u003c\/li\u003e\n\u003cli\u003eFive-year parts and labor warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhy Deus II Owners Reach for the 13 x 11 inch FMF Coil\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eWider 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.\u003c\/li\u003e\n\u003cli\u003eFull 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.\u003c\/li\u003e\n\u003cli\u003eWireless design with coil-housed electronics and battery delivers up to 20 hours of runtime per charge, depending on the program and frequency selected.\u003c\/li\u003e\n\u003cli\u003eWaterproof to 20 meters (65 feet) supports full submersion for river wading, surf hunting, and shallow-water diving, well past what wading-rated coils handle.\u003c\/li\u003e\n\u003cli\u003eElliptical geometry offers better maneuverability around obstacles and tighter target separation in iron-heavy sites compared to round coils of equivalent sweep width.

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 \u003ca href=\"https:\/\/seriousdetecting.com\/pages\/metal-detector-technologies\"\u003ethe technologies behind modern detectors\u003c\/a\u003e helps explain why simultaneous multi-frequency operation holds a stable signal in conditions that defeat single-frequency coils.\u003c\/p\u003e\n\n\u003ch3\u003eBeach Hunting from Dry Sand to Surf Zone\u003c\/h3\u003e\n\u003cp\u003eSaltwater 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.\u003c\/p\u003e\n\n\u003cfigure\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0760\/1464\/9628\/files\/D3428FMF_inline_2.jpg?v=1779371204\" alt=\"Black XP Deus II 13x11 inch elliptical search coil with red branding and cross-brace design\"\u003e\n\u003c\/figure\u003e\n\n\u003ch2\u003eHow it compares to other FMF coils for Deus II\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eFeature\u003c\/th\u003e\n\u003cth\u003e\u003ca href=\"https:\/\/seriousdetecting.com\/products\/xp-deus-ii-9-round-fmf-waterproof-search-coil-lower-pole-and-hardware\"\u003e9 inch Round\u003c\/a\u003e\u003c\/th\u003e\n\u003cth\u003e\u003ca href=\"https:\/\/seriousdetecting.com\/products\/xp-deus-ii-11-round-fmf-waterproof-search-coil-lower-pole-and-hardware\"\u003e11 inch Round\u003c\/a\u003e\u003c\/th\u003e\n\u003cth\u003e13 x 11 inch Elliptical\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCoil Size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e9in (22.5cm)\u003c\/td\u003e\n\u003ctd\u003e11in (28cm)\u003c\/td\u003e\n\u003ctd\u003e13in x 11in (33cm x 28cm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e-\u003c\/td\u003e\n\u003ctd\u003e1.03 lbs (470g)\u003c\/td\u003e\n\u003ctd\u003e1.25 lbs (570g)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFrequency Range\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e4-45 kHz\u003c\/td\u003e\n\u003ctd\u003e4-45 kHz\u003c\/td\u003e\n\u003ctd\u003e4-45 kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWaterproof Rating\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e65ft \/ 20m\u003c\/td\u003e\n\u003ctd\u003e65ft \/ 20m\u003c\/td\u003e\n\u003ctd\u003e65ft \/ 20m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBattery Life\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eup to 20 hours\u003c\/td\u003e\n\u003ctd\u003eup to 20 hours\u003c\/td\u003e\n\u003ctd\u003eup to 20 hours\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e XP Deus II metal detector\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoil Size:\u003c\/strong\u003e 13in x 11in (33cm x 28cm) elliptical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Range:\u003c\/strong\u003e 4-45 kHz (49 selectable frequencies plus multi-frequency programs)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.25 lbs (570g)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWaterproof Rating:\u003c\/strong\u003e 65ft \/ 20m\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery Life:\u003c\/strong\u003e up to 20 hours (varies by program and frequency)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWireless:\u003c\/strong\u003e Yes (electronics and battery in coil housing)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 5 years parts and labor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Manufacture:\u003c\/strong\u003e France\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhy Buy from Serious Detecting\u003c\/h2\u003e\n\u003cp\u003eWe are an \u003ca href=\"https:\/\/seriousdetecting.com\/pages\/customer-care__about-us\"\u003eauthorized XP dealer\u003c\/a\u003e, which means every FMF coil ships with the full five-year manufacturer warranty and access to XP's firmware update path.
