The first detector I used on my return to detecting was the CZ 7a Pro. That first year I found 30 quality rings. I then bought and sold over twenty detectors of various brands over the next five years. My production of coins and jewelry dropped dramatically. I picked up a CZ 70 pro and started using it and in the past four months have found seven quality rings, one .80 carrat solitair in the group. The grass is always greener on the other side but in detectors the CZ series has got to be the finest all around detector ever built. Nickles and rings are never missed with the CZ. Now if Fisher would minaturize this great unit!!
