Ok I have a X-TERRA 505 that until this morning was working fine. I went to look at my detector this morning just because. I paid a lot for her I better look at her some lol. Well I notice on the screen under it is two small spots of condensation. Not sure how it got there. Then I go to turn it on starts right up but then it won't shut off. I pull the batteries to try and fix it it didn't work. Then it starts to turn off again do I figure ok well it was a fluke. I press the all metal button and it turns off. It keeps turning off everytime I hit that button. Then I check to see if any other buttons do anything. The pinpoint button does the same thing. I'm not sure what happened I used just last night. I already contacted minelab. I'm waiting on a reply now. Any ideas on what it could be?
