18" Round Commander Double-D Coil
Designed for depth in highly mineralised ground. Great for large gold and deep relics. A serious coil for the serious detectorist.
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 environmentsWater resistant: May be splashed, washed, used in drizzling rain, or moved through wet grass. Must not be submersed under water.
