For anglers who are determined not to miss a thing while out on the open water, the top-of-  the-line 797c2 SI Combo packs in all the features Humminbird has to offer. Most notable is Humminbird's exclusive Side Imaging technology, which displays picture-like images of fish, baitfish, bottom structure and terrain while scanning to the left and right of the boat up to 240 feet on each side. DualBeam PLUS sonar employs a precision 20-degree beam that's focused on the bottom to show you structure, weeds and cover, as well as a broad 60-degree beam for hunting fish in a wide coverage area. The beams can be used independently or together to give a clear picture of what's underneath the boat. You're sure to see clearly with its 640-vertical-pixel-resolution hemispherical viewing color display. To top it off, the 797c2 SI Combo has a built-in UniMap of USA inland lakes, rivers and coastal areas, and includes a precision 16-channel WAAS GPS receiver. Even water temperature and GPS speed is included. $999.99.
