Thanks for the information. I just received the unit back. No information about what was done, but just a cryptic note on the packing slip.
"Tech. Comments: (Sonar-Imaging, 27 -SI Right Incorrect/Missin, L,200)"
Any idea what this means?? As far as I know there wasn't anything "wrong" with the unit, and the side imaging worked within the limitations of non-HD transducer.
Gonna' be a while before I can test it out in the water....no sign of "ice out" here....figure it will be the end of April if we're lucky up here in the frozen tundra.
