I am having some problems with my transducer on my Humminbird unit. When I power on the unit while the boat is in the water, 90% of the time it will state that it shows transducer not connected. Sometimes I must power it off and back on multiple times to get it to read the transducer. Now if I power up the unit with the boat out of the water, it reads the transducer and works fine. Please , if anyone has any insight on this , I would appreciate the help.Thanks Guys.
