Nokta SX35 13.5x12.5" Waterproof DD Search Coil for Simplex Series and FindX Pro

The Nokta SX35 is a 13.5 x 12.5-inch waterproof DD search coil that increases ground coverage and detection depth for Simplex LITE, BT, and ULTRA detectors. Simplex owners hunting parks, beaches, and farm fields gain faster area coverage and deeper target penetration compared to the standard coil. The elliptical geometry maneuvers around obstacles while maintaining the wide sweep advantage that makes large coils effective in open terrain. This coil ships with a protective cover and mounting hardware, ready for immediate field use.

What's Included with the Nokta SX35

• Nokta SX35 13.5 x 12.5" DD Search Coil for Simplex Series and FindX Pro
• Protective coil cover
• Mounting hardware kit

Why Simplex Owners Reach for the SX35 Large Coil

• Cover more ground per sweep compared to the standard coil, cutting search time across large parks and beach zones
• Detect coins and relics deeper in mineralized soil where the larger electromagnetic field penetrates beyond the standard coil's range
• Hunt shallow surf, wet sand, and rain-soaked fields confidently with fully submersible waterproof construction that matches the Simplex body rating
• Maintain target separation in moderate trash with DD technology that balances ground coverage against the pinpoint accuracy smaller coils deliver in dense iron
• Pair the SX35 with the Nokta Simplex LITE for a budget-conscious setup delivering professional-grade coverage

Faster Beach Coverage and Deeper Park Finds

Open Beach Hunting

The SX35's 13.5 x 12.5-inch footprint sweeps beach zones faster than the standard coil, critical during narrow low-tide windows. The DD configuration rejects saltwater ground signal while the waterproof rating lets you wade into shallow surf chasing targets the stock coil would miss at depth. The elliptical shape fits between dune grass and debris lines better than round coils of equivalent area.

Park and Field Relic Hunting

Large open parks and farm fields reward the SX35's coverage advantage. You'll complete a football-field-sized search zone in fewer passes, and the increased depth helps find deeper silver coins and relics from below the standard coil's detection envelope. Mineralized soil in old fairgrounds and colonial fields benefits from the DD ground-balancing performance. Run moderate sensitivity; the larger coil amplifies ground noise in hot soil, so reduce sensitivity in highly mineralized soil.

Trade-offs in Trashy Sites

The SX35 struggles in high-density trash sites like iron-heavy tot lots and urban demolition sites. The larger coil sees multiple targets simultaneously, masking good signals under iron false positives. In those scenarios, smaller coils deliver cleaner target separation. The SX35 also demands more arm endurance during four-hour hunts; the increased swing weight fatigues shoulders faster than compact coils.
