Got an old Garret AT3 Beach hunter kicking around, all coil wires cut, have two or three coils also with the wires cut. One is a 3 inch coil. Bought as a pile just like this, was going to wire the 3 inch coil to check clay pockets for nuggets while dredging but I have too many projects. Electronics work on all. No shafts. Just the pile. Worth it for the underwater headphones. $50.00
