Nokta LD28 11" Waterproof DD Search Coil for Legend 2

The Nokta LD28 11-inch DD coil is compatible exclusively with the Nokta Legend 2 metal detector. Installation takes about two minutes: remove your current coil and swap in the LD28. The Legend 2 automatically recognizes the coil change, so there's no manual configuration required. The coil integrates with the detector's systems for seamless operation.

The LD28 is fully submersible and built for wet-condition detecting. You can take it right into the surf zone, hunt shallow rivers, or work after heavy rains without worry about water damage. The waterproof design makes it suitable for saltwater beaches where wet sand and surf exposure are constant. The DD configuration maintains stable operation in challenging wet-sand conditions. The included coil cover adds an extra layer of protection and reduces the hollow sound when dragging the coil over wet rocks or pavement.

The LD28's 11-inch footprint provides about 30% more ground coverage per sweep compared to smaller stock coils, letting you work open areas more efficiently. The larger size also delivers deeper detection range, pulling targets from greater depths in worked-out sites. However, the 11-inch coil is still nimble enough for wooded areas and around structures, unlike extreme-size coils (13-inch or larger) that become unwieldy in tight spaces. The LD28 hits the sweet spot between coverage area and maneuverability. If you're hunting large open fields or beaches, the extra coverage speeds up your search; if you're working trashy homesites or wooded relic sites, the coil remains manageable.

Your LD28 purchase includes the 11-inch DD search coil, a protective coil cover, and all mounting hardware needed for installation. The coil cover isn't just for protection: it also reduces the coil's weight slightly and eliminates the hollow sound you'd otherwise hear when dragging the coil over rocks or pavement. Everything ships ready to install on your Legend 2. The installation process takes about two minutes, and the detector automatically recognizes the new coil without requiring manual configuration. You can explore additional metal detector search coils: dd, concentric, monoloop & sef upgrades if you're comparing options across different detector brands.

The LD28’s DD (Double-D) configuration creates a precise, blade-like detection pattern engineered specifically for high-performance sorting in trashy sites and mineralized ground. The dual-D overlapping windings isolate small, highly conductive keeper targets when they are tightly flanked by heavy iron junk, preserving clean target IDs where unified fields struggle. This specialized layout inherently mitigates ground signals, allowing the Legend 2 to sustain deep target penetrations across saltwater beaches and hot, mineralized soils.

The LD28 is optimized for mineralized ground and performs well in challenging soil conditions. The DD configuration's blade-like detection pattern slices through mineralization while maintaining stable operation and accurate target ID. The optimized ground balance delivers cleaner performance in areas with high mineralization. We've found this coil particularly effective in old homesites and relic sites where ground mineralization is high and target separation is critical. If you're hunting areas where the stock coil struggles with false signals or unstable audio, the LD28's optimized ground balance will deliver noticeably improved performance.

The LD28 features lightweight construction designed to reduce arm fatigue during extended detecting sessions. While Nokta doesn't publish an exact weight specification, the coil's lightweight design makes it comfortable for four-hour hunts. The included coil cover further reduces weight and eliminates the hollow sound when dragging over rocks or pavement. The lightweight construction is a meaningful ergonomic advantage if you're planning long sessions in the field, helping you maintain comfort throughout your detecting day.

The LD28 is suitable for various detecting applications. The 11-inch size and DD configuration provide good depth and excellent target separation in trashy ground, making it effective for park hunting, old homesites, and beach detecting. The LD28's optimized ground balance performs well in challenging mineralized terrain. The LD28 shines as an all-around upgrade coil for Legend 2 owners who hunt a variety of targets and conditions, delivering deeper detection range and superior target separation compared to stock coils.
