Steve Herschbach Posted March 16, 2015 Share Posted March 16, 2015 This shows that a GPZ 7000 can be made to work on a salt water beach, at least enough for a video. It was not mentioned in the video but the TDI used for comparison was probably run with ground balance off. The TDI is a formidable beach detector in straight up non-ground balance mode.

DDancer Posted March 17, 2015 Share Posted March 17, 2015 Great info. Thanks to the testers I've not gotten down to the beach yet however the video knocks out one question I had. Link to comment Share on other sites More sharing options...
eurodigger Posted March 17, 2015 Share Posted March 17, 2015 That answers my question on beach detecting. I can get 8 TDi's for the price of one GPZ so clearly just for beach combing the GPZ wouldnt make any sense. Link to comment Share on other sites More sharing options...
1515Art Posted March 17, 2015 Share Posted March 17, 2015 I'm still a little concerned about salt air exposure to the gpz, considering the way salt affects all the electronics and everything else on my boat. Even good marine stuff can have a pretty short life and being careful is no guarantee against corrosion, I'd hate to throw my $10K detector off its delicate attitude, by insulting it with any performance altering corrosion.
