Tried it. It read 2′. Switched battery and did same thing. It’s about 5 years old. I actually talked to a buddy that does a lot of fishing and he also said the transducer is probably going bad. New transducer in the mail. Thanks for all the help and info. Chris

All connections are good. Battery is good. I keep the transducer below the bottom of the ice and I always use secondary cord for support. I usually fish anywhere from 10′-30′. I have tweeked every non back and forth. Maybe transducer went bad?
