cz 21 and ground balance

[4helements]

hello everybody
i'm going to get a brand new cz 21, but i have an important question about the ground balance
the seller told me that i need to make ground balance only if the cz works in autotune mode, while if i set it in discrimination mode the cz i dont need to make ground balance because it adjust by itself.
i dont think so, anyway, there is someone that could help me??

thanx to who is going to help me

bye

I don't think so. But you could go to Fisherlab.com & download the manual and give it a check!

Autotune mode is Fisher's way of saying ALL METAL. You GB in Autotune and that carries when you go into disc mode. It does not auto ground balance for you. Great beach detector for the wet of dry salt water sand. The older CZ6a is the land version so you can find those cheap.
