radar Posted July 29, 2011 Report Posted July 29, 2011 I'm at Bark Lake by Barry's Bay right now. My buddy installed a new Hummingbird depth finder. Lower end. Periodically it just switches to 0.6 ft. Always 0.6 And the screen is garbled. Any ideas? We've adjusted the angle but will take it apart tomorrow to try and figure it out.
irishfield Posted July 29, 2011 Report Posted July 29, 2011 Usually an air bubble under the transducer that does that. Take a scrub pad or something and lightly take the shine off the bottom of the transducer so the air bubble can't stick.
blue pickeral Posted July 29, 2011 Report Posted July 29, 2011 (edited) Have something similar happen to my Lowrance from time to time. Usually clears by adjusting transducer one 'notch' downward in its mounting bracket. (which come to thing of it, might be an air bubble problem) Edited July 29, 2011 by blue pickeral
