{"product":{"id":8289764409628,"title":"Nokta Makro C23 9\" Search Coil for CF77 Coin Finder Metal Detector","body_html":"\u003cp\u003eThe Nokta C23 delivers pinpoint accuracy for coin hunters who need maximum sensitivity in tight spaces. This 9-inch coil transforms your CF77 into a precision instrument for finding small targets other detectors miss. CF77 owners hunting old homesteads, park benches, and dense urban sites reach for the C23 when their standard coil can't separate good finds from trash. At 9 inches, it's the smallest coil available for the CF77, making it ideal for any location with concentrated metal debris.\u003c\/p\u003e\n\n\n\u003ch2\u003eWhy CF77 Coin Finder Owners Reach for the C23\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eUltra-high sensitivity detects the smallest coins and gold nuggets in mineralized ground where larger coils lose resolution\u003c\/li\u003e\n\u003cli\u003eCompact 9-inch diameter threads between bottle caps, pull tabs, and nails to isolate individual targets in crowded locations\u003c\/li\u003e\n\u003cli\u003eWaterproof construction lets you hunt creek beds, wet sand, and shorelines without worrying about coil damage\u003c\/li\u003e\n\u003cli\u003eLightweight open-frame design reduces arm fatigue during long hunts while maintaining excellent depth on coin-sized targets\u003c\/li\u003e\n\u003cli\u003ePlug-and-hunt compatibility with all CF77 detection modes means no calibration needed when you swap coils\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTighter Target Separation in Trashy Urban Sites\u003c\/h2\u003e\n\u003cp\u003eMost coin hunters eventually hit sites where their standard coil just can't squeeze between targets. That's where the C23 shines. The compact footprint excels in three core scenarios where larger coils struggle.\u003c\/p\u003e\n\n\u003ch3\u003eSchoolyards and Park Benches\u003c\/h3\u003e\n\u003cp\u003ePlaygrounds and picnic areas concentrate decades of dropped coins alongside modern trash. The C23's 9-inch diameter lets you thread between bottle caps and foil wrappers to pinpoint individual coins. We've used this coil to pull silver dimes from schoolyard sites other detectorists had already worked over with larger coils. The open-frame design sheds dirt quickly, keeping your sweep speed consistent across wood chips and mulch.\u003c\/p\u003e\n\n\u003ch3\u003eOld House Foundations with Scattered Nails\u003c\/h3\u003e\n\u003cp\u003eHomestead sites and tear-downs bury good targets among construction debris. The C23 isolates individual items in areas where a 10-inch or 12-inch coil would mask coins under the combined signal of nearby nails and wire. Many CF77 owners keep this as their go-to coil for relic recovery in these high-trash environments. The waterproof construction also means you can hunt foundation holes that collect rainwater without risking coil failure.\u003c\/p\u003e\n\n\u003ch3\u003eCreek Beds and Narrow Shorelines\u003c\/h3\u003e\n\u003cp\u003eSpace-limited hunting environments favor smaller coils. The C23 maneuvers around rocks and roots where larger coils can't reach. Gold prospectors appreciate how it isolates small nuggets from hot rocks in mineralized stream gravel. The coil works seamlessly with the CF77's discrimination patterns to reject iron while still flagging gold and silver targets in wet sand.\u003c\/p\u003e\n\n\u003cfigure\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0760\/1464\/9628\/files\/SCC23_Inline.jpg?v=1779292054\" alt=\"Black circular metal detector search coil with handle and attached cable connector\"\u003e\n\u003c\/figure\u003e\n\n\u003ch2\u003eHow the C23 Fits the CF77 Platform\u003c\/h2\u003e\n\u003cp\u003eThe C23 is purpose-built for the Nokta CF77 Coin Finder.
