I now have all the components to carry out the modifications to Minelab SD2000 detectors, this involves modifying the front end for greater depth and sensitivity and the low frequency mod for going really deep on big deep Gold the other detectors Miss. The Mods have been tested by professional prospectors at a testing site in the Golden Triangle and none came close to the depth of the modded SD2000.
All you need to do is send me the control box and when modified I post it back.
