The White's TDI metal detector features full balance ground control to quickly balance out the iron mineralisation of hot rocks, black sand and other tough ground conditions. The adjustable pulse delay allows settings from 10ms for finding gold nuggets to 25ms for relic, coin and beach hunting. The 3-way target conductivity selector allows the user to distinguish between possible targets. The TDI from Whites also has a frequency control to help when searching near power lines, microwaves or other environmental interference. The TDI comes fitted with a waterproof 12" spider search coil.
