Still havin trouble with my Lowerance 125X reading and blinkin '^0 fow" can't get it to reset to show real readings. It just keeps blinking "60". I have looked on the menu for a factory default setting but can't find one. I have turned down the strength on my imaging to jpractically nothing, as was suggested earlier, but that tdoesn't help. Shoud I be feeling or hearing some sort of pulsing or pinging sound when this thing is powered up. I 'feel' or 'hear' nothing when I put it to my ear.

Really confused and need some advice!! Yeah, I know, buy a HB. LOL
