I have a vintage White's 6000/di series 3 metal detector. It's been working fine for years. Last year we replaced the switch that changes the mode on the handle. After the switch was replaced it worked great. This year the meter needle does not move in the GEB Discriminate mode. It does not identify the target...penny, dime, quarter ect. The needle should lock on to the target until you release it using the mode change switch. The detector will work in the GEB Disc. mode but the meter does not. We have checked all the meter connection and everything looks good. Any suggestions or advise to solve this issue? Thanks.
Since you are new on here, you might not know Carl was the engineering brains for Whites before going to Garretts where I lost contact with him. He may still be there for all I know. An update from Carl would be welcome
On top of knowing a bit about detectors, he is a nice guy too. I was a field tester on the V series for him and met him down in Texas when the Vision detector was introduced to the public which was later upgraded and known as the mighty V series.
