hb 365 i problem

my unit is 2yrs old transducer is mounted on the trolling motor. it has been working fine till now, it works like it should for a little while then acts like it freezes up.it has a spilt screen on it, left side shows what they call sonar view, right side shows what they call real time sonar or (rts). say your setting in 10ft of water, both sides show 10ft, then it messes up ,left side will show 0.6ft depth, screen is black just like transducer is on bottom, right side will still be showing 10ft,it will stay like this for a while then go back to working right for a little bit then it will mess up again. does not matter if trolling motor is running or not. thanks for any ideas or help.

You should probly post this problem on the fishing electronics and trolling motors board or send a pm to humminbirdgreg on this site, I bet you'll get alot more replies ...

had this prob with a diff sonar...make sure your sonar and trolling mtr are on diff batteries if possible....i run one for cranking and sonar and another for tm...hope it helps

Hay man I had a Lowance 520 do that same stuff so I called Lowance an they had me do a hard restart sorta like you gotta do on your computer at times. Try doing that on your unit and see if that works hope it does for ya.
