I've been a Whites user for 8 or 9 years now and have done just fine with the Classic I.D. and DFX. My buddy has the IDX Pro. I do want to try another brand to see if The different circuitry and set up will help us pull some more finds out of our heavily (Whites)hunted sites. I was hunting with another friend who did better with a lower priced BH around an old iron rich foundation for buttons, than I did with my DFX. It got me thinking that a different brand may be a nice change. Now for the ???, is the CZ70 good around cellar holes? This is where i mostly hunt. The DFX has really impressed me but I do know from many hours spent detecting that the DFX tends to lose a signal on a good target next to iron. I also tried it on a beach in the Hamptons(NY) and found the depth to be poor. Would a CZ70 or other CZ work better at these sites? i'm in the market for a good used detector to make up for the Classic I gave to a friend. I'm torn b/w the Shadow X3, CZ3d, and CZ70. Thanks a bunch!
