Does the digital cz Id at depths as good/better or worse then the metered cz's. My ground is rather mild, and I'm looking to try one out.....I have had the 1270,coin strike and 1236 x2. And would like to try the dual freq Fisher....Does anyone know if Fisher will come out with another dual freq detector or are those a thing of the past.......I wonder why they stoped ? I really would like to try a cz5 or cz3d. I wasn't sure if the digital varieties had any pro's or cons to them. Thanks guys
