Throw a 480'-Wide Net
Side Imaging - Humminbird Side Imaging® Sonar uses a razor thin beam to take a "sonar snapshot" of the area up to 240 ft. to the left and right of your location. The return image for this slice is then added to the images taken immediately before and after to build an incredibly detailed view of the lake bottom.
Beam Me Up!
DualBeam PLUS Sonar - 2 beams and the best of both worlds! A narrow beam is optimized for bottom and structure detail below your boat, while a wide beam casts a wider net, searching for fish and structure around your boat. View them side-by-side onscreen or combine the images into 1 comprehensive view!
Look Out Below!
Down Imaging Sonar - Provides picture-like images of structure below your boat by combining a traditional down-looking sonar view with side imaging technology. Observe Down Imaging side-by-side on your screen with SwitchFireTM (explained below), or on a 3-way view.
Light a Fire Under Your Boat
SwitchFire - Gives you a real time, customized look below the water's surface with 2 different modes: "Max Mode" and "Clear Mode". Clear Mode filters out noise (suspended particles, etc.) in agitated or shallow (8' or less) water for a clearer image of fish and structure. Max Mode for incredible detail and easy lure monitoring. See cover, structure, fish, even thermoclines and water currents. Keep an eye on your bait or jigging action for the best lure presentation.
