I have a brand new unit and have two problems with it:(1) when i go to sonar, than full screen, i get a straight line that shows the bottom, however it clearly does not define fish and terrain features, (2) and fish id only shows big fish going across the screen and nothing else, bait fish and etc and the fish id is set on the option that should show all fish.
I would extremely happy to make contact with another who has this unit for help and suggestions. Please email me as [email protected] Thank you bill
