Hi Jim,
The test for false readings will involve adjusting the Examiner to discriminate to only find copper, then to take it across the supposedly barren test field and see if it begins moving toward any particular location. In theory, if we get a response, it would indicate there is copper in the "barren" field. This would lead us to look at the location where points and dig a hole to see if there is some copper buried below where the metal detectors didn't find it. Then remove the copper and check again for a signal. When we see there is no signal from the field, then we can place the 1 kg copper target to test. If we can't get the "barren" field clear of signals that the Examiner responds to, then I guess we need to find a different test field that will work.
I wouldn't attempt this test until after I got a confirmation from Rangertell that the Examiner is working ok. At least this is the best way I figured to do it so far. Do you have any suggestions?
Best wishes,
