    What is great is the screen resolutions, & if you take the time to actually learn how to use it, I think anybody will not be disappointed. It is rather complicated at first, but the support behind it for me has been great. I even called from the lake while fishing & humminbird techs answer all my questions I needed help with. The installation instruction are not great, but you can install the unit with them & maybe a couple of phone calls. I really like the unit. Big improvement from Lawrance X5.

          Very impressed with the menu system that lets you at least use it for basic functions without knowledge. The side imaging lets you know which side of the boat the fish you are seeing are on.

              Bought this unit online from Gander and have not regretted it. Amazing unit. There is a lot to learn before using these units and there are a lot of good You Tube Videos to assist you in understanding how to get the most out of this Finder. Would most definetly buy again. This unit works great on the trolling motor. Like this one so much, went out and bought an 859 DI for the back of the boat.

                      Depends on a few factors--but a jetboat may experience some compatibility issues to due to the extra turbulence created--especially in the Side Imaging mode.

                    I have noticed that the 798 is referred to in two ways, (1)is the 798ci HD SI - (2)is the 798CXI HD SI. Could you tell me what the difference is? Thanks Hank.

                      798ci HD SI is the North American Version. 798CXI HD SI is the international versions for markets outside of the USA and Canada. Same unit--Same Performance--just extra language sets in the formatting for non-US markets.
