I got one of the first ones made and have had to send it in twice. Am I sorry I bought it?? A big fat emphatic "NO"!!! This thing will do everything they said it would and more. Everyday I use it, I'm more impressed!! Search my posts and you'll see all the GOLD it has found for me, not to mention old coins, silver rings and plenty of clad. Am I worried it will go bonkers again??? Again, a big fat emphatic "NO"!!! Garrett stands by their product and will get you back up and running within a week or so!! I've got a fleet of detectors made by all the major brands and just about every on has had to be sent in for one thing or the other, it's the nature of the beast!!
