I bought a Humminbird down-imaging because I thought it would give a straight down image of the bottom. Not true. Down-imaging give you a verticle view of the bottom … not a horizontal (flat) view. In hindsight, I would go with side-imaging. It gives you a wider field of view and allows you to “see” under docks and into brush piles without having to pass directly over them. Also, side-imaging is required if you want to eventually go with Humminbirds “true” 360 down imaging system.
