about $4.25 in clad, nothing special, but this BH505 is a damn good detector for the money I will tell you that!! I can't wait to get my AT Pro back from Garrett (repair)......but this machine holds its own!
problem was falsing/erradic behavior, this has been for a long time, it was my first detector so i had nothing to compare it to. I used it one day and when I shut it off, it would not turn back on. It got very hot though, the batteries were hot. So I am sending it in.......I think it was just defective.
