{"product":{"id":8289323385116,"title":"Nokta LG28 11\" DD Waterproof Search Coil for Legend Metal Detector","body_html":"\u003cp\u003eThe Nokta LG28 is an 11-inch DD search coil compatible exclusively with the Nokta Legend, delivering increased detection depth and broader ground coverage for detectorists hunting expansive sites where the stock coil's footprint limits efficiency. Legend owners searching large farm fields, open beaches, or historical sites face a problem: the standard coil requires overlapping passes to cover acreage, and concentric coils destabilize in mineralized ground. The LG28 solves this with an 11-inch DD geometry that maintains stable target ID in challenging soil while sweeping a wider detection zone per pass.\u003c\/p\u003e\n\n\u003ch2\u003eWhat's Included with the Nokta LG28\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eNokta LG28 11\" DD waterproof search coil for Legend\u003c\/li\u003e\n\u003cli\u003eProtective coil cover to guard against rocks and abrasive sand\u003c\/li\u003e\n\u003cli\u003eMounting hardware for direct installation on Legend lower rod\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhy Legend Owners Reach for the LG28\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDeeper detection range on coin-sized and larger targets in open ground, reaching buried relics and caches the stock coil passes over.\u003c\/li\u003e\n\u003cli\u003eDD configuration cuts through mineralized ground interference that destabilizes concentric coils, maintaining clean target ID on red clay, black sand, and iron-rich soils.\u003c\/li\u003e\n\u003cli\u003eSubmersible durability matches your Legend's waterproof rating for wet-sand hunting and shallow-water wading, with an included coil cover that extends coil lifespan.\u003c\/li\u003e\n\u003cli\u003eWider sweep coverage reduces the number of passes required to search large sites, cutting search time on expansive fields and beaches.\u003c\/li\u003e\n\u003cli\u003eDirect installation on the Legend lower rod with included mounting hardware.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eDeeper Reach in Open Fields and Mineralized Ground\u003c\/h2\u003e\n\n\u003ch3\u003eRelic Hunting in Red Clay and Iron-Rich Soils\u003c\/h3\u003e\n\u003cp\u003eThe LG28's 11-inch DD geometry excels in mineralized soil conditions where concentric coils produce false signals and unstable target ID. Red clay, volcanic soils, and iron-rich ground destabilize single-winding coils, but the DD configuration's overlapping transmit and receive windings cancel ground interference while preserving target response.

The DD configuration handles saltwater ground phase without the false signals concentric coils produce in conductive wet sand. The 11-inch footprint covers more ground per sweep than smaller coils, cutting search time on expansive beach faces.
