I have a helix 12 on the bow with the transducer mounted on the trolling motor it has lost everything temp,2d sonar and side and down changed it to rear transducer and it reads fine . I unplugged everything and just plug power and transducer in and it starts to see 2 d than goes out and not found . I can here the transducer clicking.
any ideas ? Is humminbird having problems with the transducers ?
also it was reading 657 degrees temp and 1500 feet deep when it was in 6 foot of water and 84 degree
