Just got this , and after it warms up the signal goes fuzzy, and is barly adible tried everything adjusting frequency, ground balance, cheking plug ins it need repare it has poor depth seems like when it warms up it just gets relly fuzzy like an AM radio scratchy signal , I do not have the money to fix it i paid 520.00 I am letting it go for 275,00 shipped I guess you take a risk when you buy used detectors, this one need repear i bet it will run 200 easy. I prefer personal money order postalmoney order
