{"product":{"id":8289764835612,"title":"Nokta C28 11\" Search Coil for CF77 Coin Finder Metal Detector","body_html":"\u003cp\u003eThe Nokta C28 is an 11-inch round search coil designed exclusively for the CF77 Coin Finder, delivering deeper detection on coin-sized targets while maintaining tight target separation in iron-heavy sites. CF77 owners hunting old homesteads, school grounds, and trashy parks reach for the C28 when the stock coil isn't punching through moderate trash layers or hitting the depth they need on older coins. The 11-inch diameter sits between smaller maneuverable coils and larger depth-focused coils, giving you noticeably better coverage per sweep without sacrificing the control required to isolate individual targets around obstacles.\u003c\/p\u003e\n\n\u003ch2\u003eWhat's Included with the Nokta C28 Coil\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eNokta C28 11\" round search coil with wired connection for CF77 Coin Finder\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhy CF77 Coin Finder Owners Reach for the C28\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMedium-sized advantage balances depth performance with target separation, punching deeper than smaller coils while still isolating targets in trashy areas where larger search heads struggle\u003c\/li\u003e\n\u003cli\u003eConfined-space productivity lets you work around obstacles in old homestead sites and school grounds without the swing radius challenges that 15-inch or 17-inch coils introduce\u003c\/li\u003e\n\u003cli\u003eVersatile target detection covers coins, jewelry, relics, and small gold nuggets with improved sensitivity over the stock configuration shipped with base CF77 units\u003c\/li\u003e\n\u003cli\u003eRound configuration delivers consistent depth across the entire sweep\u003c\/li\u003e\n\u003cli\u003eWhen you need a larger coil for wide-open fields, the Nokta C45 17.5\" coil offers maximum depth and ground coverage for beach hunting and large search zones\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eDeeper Coin Recovery in Iron-Heavy Parks and School Grounds\u003c\/h2\u003e\n\n\u003ch3\u003eOld Homestead Sites with Moderate Trash Layers\u003c\/h3\u003e\n\u003cp\u003eThe C28's 11-inch footprint provides greater detection volume than smaller coils, pushing silver coins and seated coinage into range at sites where the stock coil leaves targets behind. The round geometry maintains consistent depth across your swing, so edge-of-sweep targets don't vanish when you change your angle. We've used this coil on 1800s farmstead sites where iron nails and square nails litter the ground, and the C28 isolates coin signals between the trash without the masking that larger coils introduce.\u003c\/p\u003e\n\n\u003ch3\u003eTrashy Park Hunting Where Target Separation Matters\u003c\/h3\u003e\n\u003cp\u003eSchool grounds and tot lots demand tight target separation, and the C28 delivers it without sacrificing the depth you need to reach coins below the pull-tab and bottle-cap layer. The 11-inch size lets you work around playground equipment and benches where a 15-inch or 17-inch coil forces awkward angles. Run your CF77's discrimination settings to notch out iron, and the C28 will separate silver dimes from adjacent trash targets that a larger coil would blend into a single signal.\u003c\/p\u003e\n\n\u003ch3\u003eBeach Hunting in Wet Sand and Surf Zones\u003c\/h3\u003e\n\u003cp\u003eThe C28's waterproof construction handles wet sand and shallow water, and the medium size balances ground coverage with sensitivity to small gold and silver targets. Beach hunters working the slope between dry sand and surf need a coil that punches through mineralized sand without overwhelming the detector with ground noise, and the 11-inch round configuration does that while still covering enough ground per sweep to make a morning hunt productive. For wide-open beach zones where maximum depth matters most, step up to the C45 17.5-inch coil, but the C28 is the better choice when you're working around rocks or driftwood.\u003c\/p\u003e\n\n\u003ch2\u003eHow it compares to other CF77 coils\u003c\/h2\u003e\n\u003cp\u003eThe table below compares the C28 against the larger C45 coil and protective covers available for \u003ca href=\"https:\/\/seriousdetecting.com\/collections\/nokta\"\u003eNokta metal detectors\u003c\/a\u003e.\u003c\/p\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eFeature\u003c\/th\u003e\n\u003cth\u003eNokta C28 11\" Coil\u003c\/th\u003e\n\u003cth\u003eC45 17.5\" Coil\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompatibility\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eNokta CF77 Coin Finder only\u003c\/td\u003e\n\u003ctd\u003eNokta CF77 Coin Finder only\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCoil Size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e11 inches\u003c\/td\u003e\n\u003ctd\u003e17.5 inches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eShape\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRound\u003c\/td\u003e\n\u003ctd\u003eRound\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBest For\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eTrashy sites, confined spaces, balanced depth and separation\u003c\/td\u003e\n\u003ctd\u003eOpen fields, beaches, maximum depth and ground coverage\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWaterproof\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003ctd\u003eNot specified\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003cfigure\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0760\/1464\/9628\/files\/SCC28_Inline.jpg?v=1779288375\" alt=\"Nokta C28 11\" search coil for cf77 coin finder\u003e\n\u003c\/figure\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Nokta CF77 Coin Finder only\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoil Size:\u003c\/strong\u003e 11 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape:\u003c\/strong\u003e Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e Open build, wired connection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWaterproof:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTarget Types:\u003c\/strong\u003e Coins, jewelry, relics, small gold nuggets\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 Nokta dealer\u003c\/a\u003e, which means every C28 coil ships with the full manufacturer warranty and our team's direct support.
