Seems my 705 once in a while when I try to ground balance goes into some sort of oscillation, the tones sound like a pinball machine. The only way to stop it is to turn it off ,and sometimes when I turn it back on it is still doing it. I have done several factory resets and has not helped. I wonder if it need a trip to Minelab? it is 6 months old.
