I need some help with these units. I have fished with them for almost a year, but I need some help dialing them in to capture the right amount of detail.

On the 999 I need help dialing in my side imaging. I like to fish ledges but have had a hard time locating fish.

On the 859 I just want the sensitivity accurate. My down imaging picks up a gold picture but my sonar seems off

I am sure there is much more I can do with these units that I am not doing. Any help with these units would be greatly appreciated.
