Fellow club member has one so we went to a heavily hunted park for me to swing his old tone unit. He has put O rings under all but the Sens/On knob so knobs don't move around. Desc just below arrow, and notch knob at 9:00. Narrow/Wide in middle so no notch on. It would overload on quarters and would have to lift coil up a couple inches to stop it. Is that normal? I cut sens down and still did it. I wanted to move notch knob up to 10:30 but he ask that I didn't. I would throw switch to narrow or wide to check target. I still think at this setting I would dig more trash and did. Granted new to machine but he would check them with ETrac to see what it saw. I can see why new tones may be easier as it was a little difficult to tell between the 2 middle tones. Guess I could get used to it and tell difference. He has had his over 3 years and so second nature to him. Do like the Golden but concerned about overload sound. Any help on this?
