GPZ 7000 Pi Or………..???

“So just having some fairly decent shallow discrimination on a prospecting machine would be pretty useful in many cases and save a lot of time just being able to concentrate on digging the targets that are higher probability of being gold,“

My preference is to incorporate a separate VLF circuit board or integrated VLF circuity within a Pulse Induction detector with a fast switchover from one mode to the other. The switchover could be as simple as turn off/on the appropriate transmitter. The coil would require special or additional winding/s but is doable. The display and control functions would change with the mode change.

For years when in trashy areas I have carried a modified VLF detector for discriminating and pinpointing. Currently I prefer the Equinox 800.
