Nokta LG28 11" DD Waterproof Search Coil for Legend Metal Detector

The LG28 11-inch DD coil is compatible exclusively with the Nokta Legend metal detector. It installs directly on the Legend lower rod using the included mounting hardware and requires no firmware updates or manual adjustments. The coil is not compatible with other Nokta models such as the Simplex, Anfibio, or Impact series. If you own a different Nokta detector, browse our full selection of Nokta metal detectors to confirm coil compatibility for your model.

The LG28 coil is fully waterproof and matches the Nokta Legend detector's submersible rating. You can hunt in streams, shallow water, wet sand, and the surf zone without worry. The coil's waterproof construction handles saltwater beach environments and freshwater wading, making it a solid choice for underwater metal detecting and wet-sand hunting. The included coil cover protects against abrasive sand and rocks that wear through the coil shell over repeated beach hunts.

The LG28 11-inch coil provides deeper detection range on coin-sized and larger targets compared to the stock coil, particularly in open ground and mineralized soil. Detectorists report that the LG28 11-inch coil provides deeper detection range on coin-sized and larger targets compared to smaller stock options, keeping target identification stable even when pushing through tough ground mineralization. The DD configuration's ground-balancing advantage maintains stable target ID at depth in challenging ground conditions. Actual depth varies with target size, orientation, soil mineralization, and detector settings.

Every LG28 coil ships with a protective coil cover and all necessary mounting hardware for immediate installation on your Legend lower rod. The included cover guards the coil shell against rocks, roots, and abrasive sand that wear through epoxy during field use. We recommend installing the cover before your first hunt to extend the coil's lifespan, especially if you hunt beaches, rocky sites, or areas with exposed roots and debris.

The LG28's 11-inch footprint provides wider ground coverage than smaller coils but sacrifices some target separation in densely trashy sites. If you hunt parks with heavy iron scatter, nail beds at old home foundations, or playground equipment clusters, the 6-inch LG15 or 9.5x6 LG24 isolate individual targets more effectively by reducing the detection zone. The LG28 excels in open fields, beaches, and historical sites where target density is lower and ground coverage matters more than pinpoint separation.

The LG28 coil includes all mounting hardware required for direct installation on the Nokta Legend lower rod. The hardware set contains the coil bolt, washers, and any necessary hardware for a secure connection. Installation takes a few minutes and requires no special tools or technical knowledge. The coil is plug-and-play, no firmware updates or manual adjustments are needed after mounting.

The LG28 coil works for gold prospecting when paired with the Nokta Legend's multi-frequency modes, which improve sensitivity to small gold targets compared to single-frequency detectors. The 11-inch DD configuration handles mineralized ground common in gold country, but the larger footprint reduces sensitivity to sub-gram nuggets compared to smaller high-frequency coils purpose-built for prospecting. If gold prospecting is your primary focus, consider a dedicated gold detector or a smaller coil like the LG15 for tighter target isolation on small nuggets.

The LG28 coil requires no firmware updates or manual adjustments to work with the Nokta Legend. It is a plug-and-play accessory that installs directly on the Legend lower rod using the included mounting hardware. Once mounted, the detector recognizes the coil automatically and you can start hunting immediately. Nokta designs all Legend coils for seamless compatibility with the detector's existing firmware and multi-frequency platform.

The DD (Double-D) coil configuration uses overlapping transmit and receive windings that cancel ground mineralization interference while preserving target response. This geometry maintains stable target ID in red clay, black sand, volcanic soils, and iron-rich ground where concentric coils produce false signals and unstable VDI readings. The LG28's DD design is the reason it excels on relic sites, beaches, and historical grounds with challenging soil conditions.
