CZ3D Glich?

I have a 1021 I bought a while back, works fine except when I change modes it always gives a momentary overload sound. I,ve had several Czs in the past, never one to do that. Any comments, would like to hear.

Wade, on my 1021 in disc, switching from enhanced to salt, it gives a mid tone. In all metal, switching from salt to enhanced, it gives a all metal 'wrrrip'. No overload sound.

Wade....... yes, this is normal when you switch back-and-forth between salt/enhance modes.

It does that on both my CZ6a's so I I agree with Tom...normal.

That was my mistake, I compared it to a knew one, should have known better, thanks guys.

My 1021 must be a freak.

Mine only does it one way,But it is a FT Detector. My 1021 I bought New did it both ways? They both work great so go figure?
