Explorer SE Pro
Water proof: Submersible to 1 meter. Ideal for shallow wading at the beach, or detecting in shallow streams.
A Double-D coil has two overlapping wire windings in the shape of two D’s. The benefits of a Double-D
coil are stability (especially in heavily mineralised ground), good depth, sensitivity and a very thorough
search pattern requiring less overlap.
When used with GPX detectors, Double-D coils (unlike Monoloop coils) are able to discriminate between
ferrous and non-ferrous targets when Iron Reject is activated. They are also more stable when used on
wet salt beach sand and in electrically noisy environments.
When used with X-TERRA detectors, Double-D coils perform quieter than Concentric coils in mineralised ground and are therefore well suited for gold prospecting.
