Maximize Your Angling Experience

Humminbird Ethernet Networking

Spend less time fiddling with wires and more time filling your livewell. Available with our latest 700 Series color models on up, new Humminbird Ethernet Networking allows you to share views, transducers, GPS positions, and more. What's in it for you? Try blazing-fast speed and maximum flexibility on the water. Directly connect unit upon unit to assemble a fishfinding force of nature. With no complicated connections or expensive wiring, finding fish has never been easier or faster.

DualBeam Plus

Get the best of both worlds, with selectable narrow and wide beams you can view individually, or melded into one display. A precision 20° beam provides high accuracy returns of fish, structure, and bottom profile. The wider 60° beam provides greater coverage for fish and bait fish. You can view the two beams separately, side by side, or blended together for the most complete picture.

Switchfire Sonar

When you hit the water, you don't limit yourself to one bait. So why limit your sonar? Exclusive Humminbird SwitchFire Sonar gives you the power to choose how returns are displayed. With two unique modes, you have complete control to adjust with the fishing conditions, making our down-looking sonar an even more valuable fishfinding tool.

Split Screen Zoom

Split Screen Zoom increases the displayed resolution to separate sonar returns that are very close together. In this view, the display is split to show a narrow slice of the full range view on the right and the zoomed view on the left. The zoom preview box on the right tracks the bottom in the full range view.

Freeze Frame/Structure Marking

Pressing any arrow on the four-way cursor control instantly stops the sonar graphic display to allow a closer inspection of submerged structure, bait fish, and underwater contours. Movable cursor feature allows you to instantly discern depth of any sonar return and mark waypoints from the sonar screen for navigation. Pressing the EXIT key will exit the freeze frame and the display will start to resume scrolling. Mark the location of fish-attracting structure, bottom transitions, or any feature anywhere on traditional sonar with the Sonar Cursor.

Selective Fish ID+

Fish ID+ uses advanced sonar processing to interpret sonar returns, and displays a Fish Symbol when very selective requirements are met. When a fish is detected, a fish icon and its depth are displayed above the return that has been classified as being a fish. Three different fish icons represent intensity of the sonar return, and provide an indicator of relative fish size.

Real Time Sonar (RTS) Window

A Real Time Sonar (RTS) Window appears on the right side of the display in the Sonar View only. The RTS Window always updates at the fastest rate possible and shows only the returns from the bottom, structure, and fish that are within the transducer beam. The RTS window can be displayed as narrow (standard), wide, or off.

Sonar Echo Enhancement

Sonar Echo Enhancement shows fish, bait, and more--even watch your vertical jigging on-screen. This is possible through advanced sonar processing and provides the details you want and need. It's important to know what depth the fish are located and equally important to be able to place your lure at that precise depth. Be careful! You may jerk the rod early while watching the screen instead of waiting for the actual bite.

TreuArch Technology

Many competitive sonar products commonly use post processing software to "enhance" the arching effect produced when suspended targets enter and leave a sonar beam. This additional processing can slow down performance and exaggerate the information displayed. Humminbird�s TrueArch Technology utilizes parallel processing of sonar data to eliminate unwanted interference and noise and reveal unaltered sonar echoes resulting in true arches of fish targets. This helps anglers more quickly discern the size and depth of fish targets.

Built-In U.S. ContourXD Maps

Humminbird has upgraded the free, built-in cartography software on the 788ci HD Combo. All-new ContourXD by Navionics is an enhanced, professional mapping package. With over 3,000 U.S. lake maps in the database, you will be able to find a lake close to any location you might want to wet a line. As an added bonus, ContourXD maps will feature depth contour lines, so you can find all the drops, bumps and channels holding fish. The maps will also include U.S. lights/markers, and major roads and interstates. Fish like a pro on your home lake, or a lake far from home, thanks to Humminbird ContourXD.
