Lowrance HDS 5 help

[gill]

Does the unit show clutter when you are not moving? Try turning down the sensitivity setting. How old is your unit? My transducer took a crap after three seasons and showed a bunch of clutter. Replaced the ducer and it was fine. Lowrance had issues with ducers freezing during winter storage. Try putting your unit on another Lowrance transducer.
Good luck.

I have the same unit...If you go into the Sonar settings, set it to "fresh water" as opposed to shallow water. It will help alot. Also there is an update for that unit. Check the Lowrance website for the free update. You will have to go back through and reset some of your preferences, but it does seem to read the bottom, while running, better.
