I have a great working Bermnie Vibraprobe that I bought new for $165 last year. Does anyone else use one? If so does it work good for you as well? If I took a notion to trade it for a beginner model metal detector for my son (such as a Tesoro compadre or Garrett ace 250 or fisher 1200 or equivalent ) would I have any luck? I've talked to a couple of other people and they love their probe. But I wanted more opinions from you guys to make sure before I let somebody sucker me out of it
