Tony,
I just got my TDI Beach Hunter in today and want to thank you for the tips. Earlier today I did some test in the back yard on some coins. It was just air testing but what you just mentioned about the GB being on and off matched up to what I was seeing in my air testing. It's good to know the GB thing is performing simular on other TDI Beach Hunter detectors and may be a norm with this detector.
I still got to get mine to the beach and look forward to learning the detector.
Again thanks for the performance tips on how to run the detector.
All The Best,
Bill G
