HI All;

I have a Datamarine Corinthian II Depth Sounder. Today it stopped reading depth, but it is getting power. I just reads "- - -" the way it does when there is more than 400 feet of depth. The numbers work in that I can set the depth alarm. Anyone have an idea where I should start? The unit has never given me a lick of trouble.

Thank you in advance for your thoughts.

Ron
