Hey,
Thanks for the quick reply. Sorry, I have been busy and haven't been able to get on the boat to much since posting last time. I had it out recently, and took some pictures and got a little better understanding what I'm working with. In the coming weeks I will be taking it out often. I will show you the pictures of my settings.
I do have a trough hull transducer installed with a y cable. From my understanding it is suppose to be used to show depth while on plane. That is one other occasional problem i seem to have. It works on plane around 80% of the time. At times it will display a depth of 1.6ft when it is much deeper. Is this through hull transducer also used for 2-D sonar? I have the hi-def side-scan transducer selected. Does the 2-D sonar display still come from the through hull transducer?
These pictures below are all on a hard bottom. It is mostly rock with a little sand mix. I took several pictures in max mode and several in clear mode. In clear mode it barely picked up the bottom. In max mode it had trouble at lower sensitivities, and at higher sensitivities it did better, but the screen had vertical lines and did not show any detail.
I'm really happy with the side imaging now. The transducer angle was slightly off in the past. Also, I really like the units. My unit at the trolling motor works great. The sonar is very good on that unit.
