CZ 21 tips

[Bud-sc]

I need some help with this detector. I am still learning it but I am not getting the depth that I should be. Tonight before coming home I did a test. I found a fresh bottle cap and bury it 10-12 inches in the sand cover it back up. I took the CZ 21 went across it and got nothing!!! Not even a false or nothing on Discrimination. I jack up the sensitivity to 10 got nothing!! Next I put it on Auto tune started it on 8 nothing!!! Then 10 nothing!!! The deepest target I have dugged up is around 7 inches. I am not sure if I am doing something wrong?? OR I am so use to my Sovereign GT with that I can get a quarter 15 inches no problem with detech 15x12 coil.I ground bal the CZ 21 on the beach I get nothing so I do what the manual say which is leave it on 10. Any ideas?? How deep will the CZ 21 pick up a quarter on avg?? I will do another test tomorrow. Thanks Bud-sc

I'd have to say something not right with your cz, especially in neutral sand where it doesn't GB. In zero mineralized sand/soil, it should go as deep as it air tests. My cz air tests at over 12" (8" coil) and will hit a coin that deep in salt sand. Inland, it will hit a coin at 10"... in my fairly mineralized soil. About 1-1/4 deeper with the 10-1/2 coil, all around.

What was the fix? Cranking up the ground balance?
