Eagle 350c at IDOfishing.com

Hi all... new to the group... just got the Eagle 350c for the front of my bass boat... I live on Lake Hartwell in S.C. It is a very clear lake. I have the unit mounted on the front of my bass boat to use when I am fishing from the front position. The transducer is mounted to my trolling motor. I fish for large mouth bass... so what are the optimum settings that I should use to see the underwater structure (shallower than 40 feet) and to mark fish (with arches vs. Fish ID)? I am looking for the best set of settings (charts speed, ping speed, noise filtering, depth range, etc. etc. I can use for this very clear lake with lots of bass. Any help would be greatly appreciated. I have tried several various settings, including the factory settings, but have not found the ideal settings and thought that someone might have a good set for me to work from. I just installed it yesterday and I have the HD Lowrance at my console.. which works like a champ! Thanks for any help!
