All, I evidently need to replace the battery in my Deus 2 controller as it will not charge at all. I charged it for several hours the other night and now nothing. The coil will work with the headphones so I know those items are good. Battery is a little over two years old so a little surprised it would go belly up this quick. The other day while detecting all was well until I turned it off and half hour later it wouldn't turn back on. Are the batteries for the controller the same as for the headphones and pinpointer? And where would I get one? Thanks for any suggestions!
