The internal GPS antenna provides you with fast information for accurate chartplotting, and it also comes with an SD card slot so you can add maps as needed.
With the dual beam sonar and down imaging technology there is very little that won’t be detected in the water.
Humminbird designed this GPS combo to be easy and convenient to use for anglers of all skill levels.
5-inch color display
Even the best GPS chartplotter/fishfinder is useless if you can’t see the display, and Humminbird ensured that this won’t be a problem with the 688ci. It comes with a 5 inch color display that boasts 480 x 640 pixels to ensure images are crisp and clear, even in direct sunlight. It also comes with backlighting to cut down on glare and make it easier to see when you are fishing at dawn or in the evening.Click to see the price on Amazon!
Internal GPS antenna & Navionics charts and maps
With the internal GPS antenna you can easily navigate unfamiliar waters, especially when it is combined with Navionics maps and charts. The 688ci comes preloaded with a map card so you can get started charting the best places to fish in your area. When you are ready to travel, the handy card slot allows you to add more maps and charts. Furthermore, this unit allows you to save routes and waypoints so you can always find your way back to your favorite fishing spots. What really sets the 688ci apart is its dual beam sonar that is capable of up to 4000 watts of power. This ensures that every detail on the bottom is clearly transmitted, along with underwater structures and nearby fish. When this is combined with the down imaging sonar every detail is crisp and clear. This makes it easier for you to separate bait fish from potential targets so you know exactly where to cast to get a bite.
User-friendly design and interface
The Humminbird 688ci is designed to be easy and convenient to use when you are out on the water. The controls are clearly marked for easy navigation through the menu, and there are three buttons that can be preset so you can quickly go back to your favorite images. The included mount for the display can be tilted to avoid glare from direct sunlight, and it can be easily removed and mounted into the dash. The transducer also comes with a convenient mount, and necessary hardware.
Easily find the best places to fish in your neighborhood or on vacation with the 688ci from Humminbird. It is easy to use and capable of quickly displaying accurate data so you can get the most from your fishing trip.
