The 1 grain ingot, the half gram gold coin, a half sovereign gold coin. Test coils will be with a small coil and a large coil.

The machines will use the same fully charged battery pack, same coil, same targets, same test location and conditions on the same day etc. My intention is to focus on small gold performance, the threshold smoothness, the ability to use gain, basic performance and handling characteristics under different circumstances. The opportunity to do a comparison cannot and should not be ignored. So the modified machine is probably not a keeper, I don't want two Tdi Pro machines. The specifics related to the modifications are not known by me, other than that they were conducted by 'Luke'.Oz Digger. My old mate had his machine modified to smooth out the threshold and to add some sensitivity. My machine is mounted on an Anderson shaft and is factory spec. The passing of a friend unfortunately has led to me taking ownership of a modified Tdi Pro. ![]()
