I know it's not rocket science... but I installed a new HumminBird 596c HD depthfinder this week, with the transducer. I followed the directions, measurements and all that. Guess what...I was depthfinderless on a 3 day shrimping trip this week. It was not reading at cruise - and it was. It was not reading at drift - and it was. It didn't read deep- and it did. It didn't read shallow - and it did. I could not find one thing that made sense between all this. I have to assume a bad transducer installation (since I did it). But it would read at time, then not. In areas of 600' depth it would read 1200', and alot of the time it was reading shallow - like single digits. The only time it seemed to work right was in really shallow water - when we were running in 20' or less.
What shop in Anchortown is reputable, and will re-install or trouble shoot a customer installation? I tried monkeying with it on the water but that was pretty hard - and **** cold. Tried rocking of forward and back, and even a little side to side rotation.
Or if someone is a whiz at them... PM and we'll work something out.
Boat is my 24' Hewes and a brand new Humminbird 596c HD with included transducer.
