Went yesterday. Played with electronics most of the day. I am trying to learn to read 2D without "little fishies". Noticed DI worked best at speeds of between 3 and 6 MPH. The 2D and DI both showed thin lines, indicating bottom softness. Some of the 2D readings showed spots with yellow middles, I guess indicating a hard reading but not an actual arch. I am determined to learn how to read 2D without the fish icons. I still have a ways to get there,but I am having fun. Any tips would be appreciated.......Thanks....crappie1133
