Screen and Display Quality
The screen on the 798ci is one of the best in the 5″ display market. The key to the display is the use of 640 x 640 pixels. By using that many pixels the fishfinder has exceptional brightness, clarity and color. One of the advantages of such a clear resolution is that when zoomed in maps and sonar images are very sharp. Another nice screen feature is the ability to view sonar images and maps at the same time. One of my favorite uses of that ability is to use lake maps and the GPS to get into my fishing spot and using the side view sonar at the same time to find my favorite structure on the bottom.
