The 859ci comes with a large 7 inch display that can be a little awkward to hold, but it is worth it when you see how crisp and clear the maps and sonar images are. The backlit LED display is easy to read in any light, including the bright afternoon sun that usually causes a distracting glare on other displays. It also comes with split screen functionality so you can compare sonar images with the GPS map, and mark each area accordingly. While the display is larger than many other portable fish finders, it should be noted that it only weighs a little over 7 pounds so it is still easy to carry with the rest of your gear.


Humminbird has made sure that you can detect almost anything in the water with the dual beam and Downvision sonar. With the dual beams you can easily see targets and objects in shallow and deep water. The wide angle also allows you to see in the cone, and with the down imaging sonar the images will appear in photo style on the color display. This makes it easier to see exactly what you are looking at, which is always an advantage whether you are a beginner or an experienced angler.


This portable fish finder comes with everything you need to get started, including a convenient carrying case for easy transporting. The case also helps to protect the sensitive electronics from water damage. The display comes with preset access buttons so it is easy to program, and the instructions can be found on the manufacturer’s website. You will also appreciate the dual card reader so you can save sonar images to review at a later date.
