I have Helix 9 Mega Side image Gen3 that I got back in September. I have stumbled through several of the menus but wanted to see if someone has a quick start guide on dialing in some of the settings. I fish fresh water (Bass) in Texas from 2 ft to 30 ft. The down and side images look good but not near as detail or bright as ones I see on here. This time of year I am looking for schools of shad and fish close by but don't seem to have the resolution I was hoping for. I have scheduled a class in December but wanted to see what I could find here. I know I am only using a fraction of the abilities of these units. Thanks in Advance!
