I just ordered a cz3d it should be here early next week. just wondering how it does for depth compared to a f75 in hot ground in nw pa. my f75 ground balances at 68 to 70 with 3 bars. I didn't think that was too bad but I can only hit coins to 7 inches in my test garden with iffy vdis. figured id try a cz and give it a go. I have plenty of 1800s yards to detect that aren't to trashy and a lot of guys seem to talk highly of it for those kinds of sites. any thoughts or tips would be appreciated. thanks
