{"product":{"id":8289441087772,"title":"Nokta IM19 7.5x4 Waterproof DD Coil for Impact Metal Detector","body_html":"\u003cp\u003eThe Nokta IM19 7.5x4 Waterproof DD Coil is an elliptical search coil engineered for the Nokta Impact metal detector. Impact owners working trashy parks, crowded beaches, and historic sites gain tighter target separation and improved small-target sensitivity from the 7.5-inch-by-4-inch footprint. The DD configuration reduces ground mineralization interference and delivers cleaner signals in mineralized soil common to relic hunting and coin shooting. Complete waterproof construction supports beach detecting and shallow water hunting.\u003c\/p\u003e\n\n\u003ch2\u003eWhat's Included with the Nokta IM19 Coil\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eNokta IM19 7.5x4 Waterproof DD Search Coil for Impact\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 Nokta Impact Owners Reach for the IM19 Coil\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eElliptical shape maneuvers around playground equipment, fence lines, and foundation corners where round coils struggle\u003c\/li\u003e\n\u003cli\u003eDD configuration balances ground automatically in high-mineralization soil, reducing false signals on iron-rich sites\u003c\/li\u003e\n\u003cli\u003e7.5x4 footprint isolates individual targets in trash-dense environments, pulling coins from nail beds and pull-tabs\u003c\/li\u003e\n\u003cli\u003eWaterproof housing performs in surf, rain, and wet sand without signal degradation\u003c\/li\u003e\n\u003cli\u003eLighter swing weight reduces fatigue during long grid searches in confined spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTighter Target Separation in Trashy Park Sites\u003c\/h2\u003e\n\u003ch3\u003eUrban Tot Lots and Picnic Areas\u003c\/h3\u003e\n\u003cp\u003eThe IM19's narrow 4-inch width slips between aluminum can fragments and bottle caps that mask coin signals under round coils. Impact operators working mulched playgrounds and grassy picnic zones report cleaner target ID on clad dimes and quarters buried among modern trash. The elliptical footprint covers less ground per swing but isolates individual conductors, so you dig fewer junk targets. Run the Impact in Park 1 or Park 2 mode with the IM19 mounted and sweep slowly; the DD coil's ground-balancing advantage shows up as stable threshold and repeatable VDI numbers on shallow silver.\u003c\/p\u003e\n\n\u003ch3\u003eRelic Sites with Iron Scatter\u003c\/h3\u003e\n\u003cp\u003eColonial homesites and Civil War camps layer iron nails, horseshoes, and plow debris across the target zone. The IM19's DD field pattern rejects broad iron signatures while preserving response to small high-conductors like buttons and bullets. We've used the IM19 on mineralized red clay and found the coil tracks ground phase shifts without constant rebalancing. The 7.5-inch length provides good depth on coin-sized targets in moderate soil. Understanding how these specialized \u003ca href=\"https:\/\/seriousdetecting.com\/pages\/metal-detector-technologies\"\u003emetal detector technologies\u003c\/a\u003e handle adjacent square nails ensures you pick the right footprint for iron-dense sites, helping you unearth masked relics that larger stock options overlook completely.\u003c\/p\u003e\n\n\u003ch3\u003eSaltwater Beach Hunting in Wet Sand\u003c\/h3\u003e\n\u003cp\u003eThe IM19's waterproof rating supports surf-zone detecting and shallow wading. Saltwater beaches challenge single-frequency detectors with conductive ground signals; the DD coil's figure-eight field reduces salt interference compared to concentric designs. Impact owners running Beach mode with the IM19 report stable operation in wet sand and the ability to hunt the wave cut without constant sensitivity adjustments. The narrow profile cuts through shell hash and seaweed clumps, isolating rings and coins that wider coils average into the surrounding matrix.\u003c\/p\u003e\n\n\u003cfigure\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0760\/1464\/9628\/files\/17000139_Inline.jpg?v=1779307131\" alt=\"Nokta IM19 waterproof DD coil with attached cable on white background\"\u003e\n\u003c\/figure\u003e\n\n\u003ch2\u003eHow It Compares to Other Impact Coils\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eFeature\u003c\/th\u003e\n\u003cth\u003e\u003ca href=\"https:\/\/seriousdetecting.com\/products\/nokta-im13-5-waterproof-dd-search-coil-for-impact-metal-detector\"\u003eIM13 5\"\u003c\/a\u003e\u003c\/th\u003e\n\u003cth\u003eIM19 7.5x4\u003c\/th\u003e\n\u003cth\u003e\u003ca href=\"https:\/\/seriousdetecting.com\/products\/nokta-im24-9-5-x-5-waterproof-dd-search-coil-for-impact-metal-detector\"\u003eIIM24 9.5x5\u003c\/a\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCoil Size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e5in round (12.7cm)\u003c\/td\u003e\n\u003ctd\u003e7.5in x 4in (19cm x 10cm)\u003c\/td\u003e\n\u003ctd\u003e9.5in x 5in (24cm x 13cm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCoil Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDD\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\u003eWaterproof\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFully submersible\u003c\/td\u003e\n\u003ctd\u003eFully submersible\u003c\/td\u003e\n\u003ctd\u003eFully submersible\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompatibility\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eNokta Impact only\u003c\/td\u003e\n\u003ctd\u003eNokta Impact only\u003c\/td\u003e\n\u003ctd\u003eNokta Impact only\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBest Use\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eExtreme trash, tight spaces\u003c\/td\u003e\n\u003ctd\u003eTrashy parks, confined areas\u003c\/td\u003e\n\u003ctd\u003eBalanced coverage, moderate trash\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoil Size:\u003c\/strong\u003e 7.5 x 4 inches (19 x 10 cm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e DD (Double-D)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape:\u003c\/strong\u003e Elliptical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWaterproof:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Nokta Impact Metal Detector\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIn the Box:\u003c\/strong\u003e Coil cover, mounting hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhy Buy from Serious Detecting\u003c\/h2\u003e\n\u003cp\u003eSerious Detecting is an \u003ca href=\"https:\/\/seriousdetecting.com\/pages\/customer-care__about-us\"\u003eauthorized Nokta dealer\u003c\/a\u003e, so your IM19 coil ships with the manufacturer warranty and our team's field support.
