I've had it for a few years and always wanted to get more serious about hunting as a hobby, but never really had the time and honestly, I don't think I use it correctly. I've found a lot of coins, buttons, etc with it though. I've decided to sell it hoping someone would get good use out of it. What should I ask for a price? I have headphones as well. The only difference from the stock photos below are that mine is the lock/unlock style, not on/off.
