Deus II owners hunting urban parks, open farm fields, and saltwater beaches reach for this mid-size round footprint when they need the ultimate balance of deep target penetration and rapid recovery speeds. As an essential piece of the FMF family, it stands as the ideal core upgrade or primary replacement path for your factory setup.\u003c\/p\u003e\n\n\u003ch2\u003eWhat's Included with the XP Deus II 11\" FMF Coil\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eXP Deus II 11-inch round 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 11\" FMF Coil\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eThe versatile frequency coverage captures low-conductor micro-jewelry and high-conductor deep silver on a single coil, saving you from swapping hardware when transitioning from a park hunt to a saltwater surf session.\u003c\/li\u003e\n  \u003cli\u003eWireless design with internal electronics and a battery sealed inside the coil frame provides up to 20 hours of field runtime, depending entirely on the program and frequency selected.\u003c\/li\u003e\n  \u003cli\u003eWaterproof submersion rating down to 20 meters (65 feet) supports deep surf hunting, river wading, and diving applications, far exceeding traditional wading-rated gear.\u003c\/li\u003e\n  \u003cli\u003eThe 11-inch round geometry serves as the ultimate \"sweet spot\" configuration—maximizing sweep coverage across expansive sites without causing the swing fatigue associated with heavy, oversized options.\u003c\/li\u003e\n  \u003cli\u003eAdding an extra FMF configuration allows you to split your system: pair one coil directly to your remote control and a secondary wireless option to your headphones for two ready-to-hunt setups.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cfigure\u003e\n  \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0760\/1464\/9628\/files\/D22FMF_Inline_01.jpg?v=1779373609\" alt=\"Black 11-inch round metal detector search coil with red accent stripe and hardware assembly\"\u003e\n\u003c\/figure\u003e\n\n\u003ch2\u003eDeep Target Penetration in Complex Environments\u003c\/h2\u003e\n\u003ch3\u003eSifting Urban Parks and Schoolyards with the XP Deus 2 Platform\u003c\/h3\u003e\n\u003cp\u003eOld park sites littered with iron trash, pull tabs, and structural debris require a coil that can isolate clean non-ferrous signals from surrounding junk. The 11-inch FMF coil features a remarkably fast recovery speed, allowing it to register deep coins wedged tightly against iron targets. Utilize the factory multi-frequency programs to achieve a wide spectral response across mixed targets, or drop down to a single frequency when surgically hunting a specific target type. The balanced round footprint minimizes masking, giving you maximum target clarity in heavily contaminated soils. Using a dedicated \u003ca href=\"https:\/\/seriousdetecting.com\/collections\/coils-wireless\"\u003ewireless coil design\u003c\/a\u003e also frees you from heavy external control boxes or heavy structural components.\u003c\/p\u003e\n\n\u003ch3\u003eSaltwater Beach and Surf Hunting\u003c\/h3\u003e\n\u003cp\u003eSaltwater coastlines present brutal ground mineralization that can easily overload basic single-frequency detectors. Operating in simultaneous multi-frequency mode allows this coil to automatically track and compensate for shifting ground phases along wet sand transitions and active surf zones.
