570di

I know this is a generic question but....can anyone tell me what would be the best settings (better than factory) for the 570di. Scroll speed, sensitivity, stc. I know this would change according to water conditions, and that I just need to play with it. I'm just trying to get a head start.

On my DI unit I start at sensitivity set to 5, chart speed set to boat speed plus 1 (this exaggerates the picture slightly which seems to work for me), and I use the 455 beam.
