Humminbird® 688ci HD DI Combo. Get an eye-opening picture of the action below, mapped out in a full-color, HD presentation!

Don't drop a blind line. Wide-coverage DualBeam PLUSTM sonar and Down ImagingTM technology combine to present a clear vision of fishing success on the backlit, 256-color high-definition display. Meanwhile internal GPS ensures you can always find your way back.

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.

Keep Going Back to the Well

GPS track-plotting and chart-plotting made easier than ever before! With push-button simplicity, you'll be able to track GPS speed, mark 2,500 waypoints, chart 45 routes, and mark 20,000 points of interest. Make note of the exact location of those hot spots!
