Hello from new CZ-21-8 user

The Lost Ring

Well-known member
Hello to everyone.
I am an underwater hunter and an excalibur II user. I recently bought a cz-21-8. I joined this forum while searching for information about the cz-21. I will share my experiences in the future.
Happy hunting.

I tend to hunt autotune (all metal) nearly all the time in the water or on the beach and flip to discriminate 0 to listen to tone for some target ID ... the old style knobs made that easy, the newer style ones are not easy to just flip with a thumb. The old ones could be flipped easily with a thumb, even when gloved with trapper gauntlets.
Here is a picture of old style knobs showing the bigger pointer allowing the easy flip from autotune to 0:
