Description

The Nokta RC40 is the largest search coil available for the Makro Racer and Racer 2, offering a 15.5-inch by 13-inch elliptical coverage area that dramatically reduces search time in open areas. Racer owners hunting fields, beaches, or parks reach for this coil when they need to cover more ground while maintaining depth on individual coins and cache-sized targets. The Double D configuration punches through mineralized soil and salt conditions better than round coils of similar size, making it ideal for high-iron-content ground or wet sand.

• Nokta RC40 15.5″ x 13″ DD search coil for Makro Racer and Racer 2
• Protective coil cover
• Mounting hardware

Why Racer Owners Reach for the RC40

• Maximum 15.5″ x 13″ coverage area cuts search time in large open spaces like fields and beaches by sweeping more ground per pass
• Double D coil configuration provides excellent ground balance in mineralized soil and salt conditions where concentric coils struggle
• Deep detection capability finds individual coins and larger cache-sized targets that smaller coils miss entirely
• Waterproof construction matches your Racer’s submersible rating for surf hunting and shallow water detecting
• Elliptical shape maneuvers through mineralization more effectively than round coils of comparable size, compare it to other metal detector search coils: dd, concentric, monoloop & sef upgrades

Maximum Ground Coverage in Open Fields and Beaches

Beach Hunting in Wet Sand and Surf

The RC40’s elliptical footprint and DD configuration handle wet sand and saltwater mineralization without the constant retuning that round coils demand. The 15.5-inch length sweeps a wider path along the tide line, letting you cover more beach in less time while the waterproof construction allows you to wade into the surf without worry. The large electromagnetic field reaches deeper targets in packed sand where smaller coils lose depth.

Relic Hunting Old Homesteads and Open Ground

When you’re searching large fields or homestead sites with minimal trash, the RC40 finds deep relics and cache-sized targets that other coils simply can’t reach. The elliptical shape gives you directional control in iron-laden ground, and the DD coil’s ground-balancing advantage keeps your detector stable in high-mineral soils. This coil really shines on deep individual targets, though you’ll want to switch to a smaller coil when you hit trashy areas where target separation matters more than depth.

Parks and Athletic Fields

Open parks and athletic fields are ideal territory for the RC40’s wide coverage. You can grid-search a soccer field or playground perimeter in a fraction of the time a smaller coil would require, and the depth advantage means you’re finding coins below the layer most detectorists have already worked. The Double D configuration keeps your detector quiet in areas with high iron trash or electrical interference from nearby power lines.
