I wasn't able to open that link, but I think I'm in the same boat. My depth gauge only says 100.0'

the depth gauge shows the correct depth and 100 meters, and so on

When my boat gets very shallow it displays 100.0

In my boat, at any depth, it first shows correctly then 100, and so on all the time.
I do not know how to solve this problem

May need a transducer
