I'm new to metal detecting.I had a Tesoro Vaquero last summer and wasn't real impressed.Bought a CZ 70 Pro last winter.I finally got out to an old drive-inn theater.There was a guy there hunting with a Prism.I parked on the other side of the theater and ground balanced my detector.He came over to tell me he had hunted there before I got there.I promptly dug 2 old dimes,4 pennies and a small silver ring while he watched.He got upset and left.I only had a 1/2 hour to hunt.For my first time out with the CZ I really like it.
