I have an Airmar B45 depth
and temp transducer
powered by a Raymarine
DSM300 and displayed on a E90W.
Lately whenever the boat
is in shallow water
, below around 15' or so, the signal seems to go haywire. Below is a picture of what I see from the MFD. Not that the depth
is not reading anything. I was probably in around 9'-12' of water
at that point.
The problem seems to go away in deeper when both the depth and the graphical fish
finding functions seem to work
Has anyone seen behavior like this before?
