I am looking to purchase my first detector. I have never used one, but it sounds like a fun hobby. I was thinking of using one mainly on a beach and looking for jewelery and coins. In my area I have the option of a Bounty Hunter Tracker II for $89.00 plus tax, a BH Quick Silver for $149 plus tax or a Garrett Ace 150 for $170 including tax. Any thoughts or suggestions would be most appreciated!
