I posted a reply to a thread last night that described the proper relationship between chart speed and boat speed to achieve the clearest Side Images from your Humminbird Fishing System. I thought I'd augment that post with a few additional screen captures that illustrate how your Side Images should, and should not, look.

First, some background. I collect many of my Side Images on Lake Wissota, a 6000+ acre reservoir in western Wisconsin. Wissota has a very active fish crib program (for all of its mega crappies) and these articifial, square-shaped structures are great targets for Side Imaging, and for fine tuning your display. If you read In-Fisherman magazine, you may have seen this Side Image that I collected. It contains a row of fish cribs and a sunken boat.
