newbie here trying to figure out the best settings for my unit I have the 998c si at console and a 898c si at bow I played with them a little Saturday while I was fishing but didn't learn anything I fish fresh water only and deepest water probably 40ft at the most I have my side scan at 40ft out just because a friend said that it was easy for him to learn at 40 so I figured id give it a shot settings I know are different for everyone I just need a good starting point all I found the other day with the 998 was a pile of cinderblock's which was awesome full detail on screen blew me away but I never found any trees that I could tell was a tree and I was over top a few that I know for a fact was there because I could see them about a ft or so under water any help would be appreciated thanks in advance
