I'll never be able to justify the expense of a >$500 detector but I'm an electronics geek and may be able to fix one. I read about Minelabs needing repair and parts shortages etc. Downside with them is they apparently are coated with an epoxy paint and schematics aren't public. Anyway, if you have say an SD/GP, Eureka, Goldbug2, GMT or equivalent that fell in the river, got run over by your son's truck, plugged the battery in backwards, or whatever that you'd let go for cheap please send me an email. barryklein@cox.net
