10.5" Round Double-D 7.5 kHz Coil

For improved depth and ground coverage over the standard 9" Concentric, this is the coil to use. It also performs well in mineralised soils. Water resistant: May be splashed, washed, used in drizzling rain, or moved through wet grass. Must not be submersed under water.

A Double-D coil has two overlapping wire windings in the shape of two D’s (one reversed). The characteristics of a Double-D coil are stability (especially in heavily mineralised ground), good depth, sensitivity and a very thorough search pattern.

When used with a GPX detector Double-D coils (as opposed to monoloop coils) are able to discriminate between ferrous and non-ferrous targets. They are also more stable when used on wet salt beach sand and in electrically noisy environments
