When using a conventional metal detector, the ground mineralisation interferes with the signal, which substantially limits the depth at which a nugget can be detected The SD 2100v2, however uses Minelab's exclusive technology known as MPS or Multi Period Sensing. This enables the SD 2100v2 to minimise the effects of mineralisation, to penetrate deeper, and to provide you with an interference free signal. This has overcome the problem of ground noise, and the detector only produces a signal for actual metal targets such as a gold nugget. Ideal for the beginner, couple or experienced prospector. Supplied with the versatile 11 inch Double-D coil the ergonomically balanced "S-bend" shaft and the longlife 12hr battery and pouch, makes the Minelab SD 2100v2 a comfortable, high-performance machine.
