Coil Big is the world’s deepest search coil for metal detectors — a fact confirmed by independent experts across multiple forums and field tests at metal detecting events. Designed for deep searching, this coil excels at locating both large objects and smaller targets weighing 1 g or more at depths of up to 25 cm.
Compared to a standard coil, Coil Big offers up to 50% greater depth and 40% wider ground coverage, making it ideal for open terrains. Fully submersible, the coil’s body is filled with durable epoxy resin and coated with a protective black layer used in marine applications. This eliminates the need for an additional coil cover while ensuring long-lasting protection.
Exceptional in performance even in soils with high or medium salinity, Coil Big is the perfect choice for professional treasure hunters and serious metal detecting enthusiasts.
