Here is a question for some of the long time CZ users. I have had all the CZ's and I have never had any problem ground balancing by using any method. I currently use the autotune bob method and I almost always end up with a setting of 2 1/2 to 3. Here is my question. Are settings from say 1 to 4 saying that there is low mineralization or does that mean high mineralization? I was always under the impression that lower numbers meant mild ground and higher numbers meant hot ground, but to be honest, nobody ever told me that. Just wondering? Thanks R.L.
