I just finished installing my new Lowrance Elite 4 HDI. I wanted the HDS because I like the idea of having DSI, regular sonar and GPS all on one unit. The screen is actually taller than the older elite 4 models. For anyone that is planning on buying the he HDI units, these units have two cables with a total of three wires. There is one cable for power and another cable for the transducer. The ends of these cables are 3 times the size of the regular dsi units. The one problem I ran into was that the combination of all three wires was way to big for the hobie through hull insert. After some squirming I realized that the only solution was to add another through-hull fitting and put one cable-end through each of them.
