Owner's manual states "Note: In the AUTOTUNE mode, you will hear a slight "threshold" hum at maximum sensitivity but not of settings at 8 and lower."
Then the machine is "silent search" when operating in AUTOTUNE with sensitivity below 8? Can that be right? What am I missing, or not understanding? I used a CZ5 for a couple of years on salt beaches and appreciated the break, or waver, in the threshold on deeper targets. I would appreciate any feedback that could explain this to me. Thank you.
