The Elite 4 has the same great features from other models, shrunk down into a portable form factor. The Elite 4 uses CHIRP sonar that produces clear fish arcs, and sharp bottoms. DownScan helps you find fish that are living or feeding among the weeds and illustrates the lake bed. The GPS and mapping capabilities are handy, allowing you to track your speed when trolling and navigate the waters safely and efficiently. Additionally, you can save a ton of waypoints and paths so you will never forget where the fish were biting, or to mark and check out spots suggested to you by other people. The screen really isn’t that small, about the size of an iPhone 6 screen, big enough to use the multi-window display feature to use navigation, CHIRP and DownScan all at the same time. If you are on a budget, or fish in a smaller boat, canoe or kayak where you need all the space you can get, then perhaps the small and compact Lowrance Elite 4 CHIRP is the best unit for you.
