{"product":{"id":8289764507932,"title":"Nokta RC40 15.5x13 DD Coil for Racer Metal Detector","body_html":"\u003cp\u003eThe Nokta RC40 is the largest search coil available for the Makro Racer and Racer 2, offering a 15.5-inch by 13-inch elliptical coverage area that dramatically reduces search time in open areas. Racer owners hunting fields, beaches, or parks reach for this coil when they need to cover more ground while maintaining depth on individual coins and cache-sized targets. The Double D configuration punches through mineralized soil and salt conditions better than round coils of similar size, making it ideal for high-iron-content ground or wet sand.\u003c\/p\u003e\n\n\u003ch2\u003eWhat's Included with the Nokta RC40 Coil\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eNokta RC40 15.5\" x 13\" DD search coil for Makro Racer and Racer 2\u003c\/li\u003e\n\u003cli\u003eProtective coil cover\u003c\/li\u003e\n\u003cli\u003eMounting hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhy Racer Owners Reach for the RC40\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMaximum 15.5\" x 13\" coverage area cuts search time in large open spaces like fields and beaches by sweeping more ground per pass\u003c\/li\u003e\n\u003cli\u003eDouble D coil configuration provides excellent ground balance in mineralized soil and salt conditions where concentric coils struggle\u003c\/li\u003e\n\u003cli\u003eDeep detection capability finds individual coins and larger cache-sized targets that smaller coils miss entirely\u003c\/li\u003e\n\u003cli\u003eWaterproof construction matches your Racer's submersible rating for surf hunting and shallow water detecting\u003c\/li\u003e\n\u003cli\u003eElliptical shape maneuvers through mineralization more effectively than round coils of comparable size, compare it to other \u003ca href=\"https:\/\/seriousdetecting.com\/collections\/coils\"\u003emetal detector search coils: dd, concentric, monoloop \u0026amp; sef upgrades\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eMaximum Ground Coverage in Open Fields and Beaches\u003c\/h2\u003e\n\n\u003ch3\u003eBeach Hunting in Wet Sand and Surf\u003c\/h3\u003e\n\u003cp\u003eThe RC40's elliptical footprint and DD configuration handle wet sand and saltwater mineralization without the constant retuning that round coils demand.

The elliptical shape gives you directional control in iron-laden ground, and the DD coil's ground-balancing advantage keeps your detector stable in high-mineral soils. This coil really shines on deep individual targets, though you'll want to switch to a smaller coil when you hit trashy areas where target separation matters more than depth.\u003c\/p\u003e\n\n\u003ch3\u003eParks and Athletic Fields\u003c\/h3\u003e\n\u003cp\u003eOpen parks and athletic fields are ideal territory for the RC40's wide coverage. You can grid-search a soccer field or playground perimeter in a fraction of the time a smaller coil would require, and the depth advantage means you're finding coins below the layer most detectorists have already worked. The Double D configuration keeps your detector quiet in areas with high iron trash or electrical interference from nearby power lines.\u003c\/p\u003e\n\n\u003ch2\u003eHow it compares to other Nokta search coils\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eFeature\u003c\/th\u003e\n\u003cth\u003eC45 17.5\"\u003c\/th\u003e\n\u003cth\u003e\u003ca href=\"https:\/\/seriousdetecting.com\/products\/nokta-inv56-22-x-19-waterproof-dd-search-coil-for-invenio-metal-detector\"\u003eINV56 22x19\u003c\/a\u003e\u003c\/th\u003e\n\u003cth\u003eRC40 15.5x13\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCoil Size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e17.5\" diameter\u003c\/td\u003e\n\u003ctd\u003e22\" x 19\"\u003c\/td\u003e\n\u003ctd\u003e15.5\" x 13\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eConfiguration\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eNot specified\u003c\/td\u003e\n\u003ctd\u003eDD\u003c\/td\u003e\n\u003ctd\u003eDD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompatibility\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCF77 Coin Finder only\u003c\/td\u003e\n\u003ctd\u003eInvenio only\u003c\/td\u003e\n\u003ctd\u003eRacer and Racer 2 only\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNot specified\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eNot specified\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003ctd\u003eYes\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\u003eSize:\u003c\/strong\u003e 15.5\" x 13\" (40cm x 33.5cm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e Double D (DD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Makro Racer and Racer 2 only\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Waterproof open coil design\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Items:\u003c\/strong\u003e Coil cover and mounting hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhy Buy from Serious Detecting\u003c\/h2\u003e\n\u003cp\u003eWe're an \u003ca href=\"https:\/\/seriousdetecting.com\/pages\/customer-care__about-us\"\u003eauthorized Nokta dealer\u003c\/a\u003e, which means your RC40 coil ships with the full manufacturer warranty and our team's backing.
