I have a Tacktick depth sounder T905 wired into a hull transmitter. I sent the unit back for testing and it was verified to be working correctly. When I switch the unit on, sometimes it shows 3 dashes, and then sometimes it shows the depth. The depth will show for a minute or so, then it goes back to 3 dashes, then it will show depth again. Can anyone tell me what is going on and why it wont show depth consistently?
