The Hummingbird Fish Finder 858c DI Combo is also one of the newest Humminbird fish finder models. It’s not just a device for finding fish, it’s also a great navigational tool. This fish finder is basically the 858c SI Combo model, but without the Side Imaging technology. Therefore, if you don’t really want the SI option on your fishfinder, this unit might be the one for you. It’s also cheaper than the 858c SI Combo, by quite a fair amount.
The Hummingbird Fish Finder 858c DI Combo features quite a big screen, just like the other units in the superior, 800, 900 and 1100 categories. Its screen has a diagonal of 7 inches, with a pixel resolution of 480 x 800. It’s full color and it’s display is a CCFL backlight type. Therefore you will benefit from nice and clear images even in direct sunlight or at night.
As its name suggests it, the most important advantage of this unit for finding fish is the Down Imaging, reliable in waters up to 250ft. deep. This feature will allow you to see, in almost photo-like clarity the contour and cover of the bottom, and of course, see the fish under your boat. Equipped with an optional 200/50 kHz transducer, this unit is reliable even in waters 3,000ft deep, in SwitchFire mode.
This Hummingbird fish finder has DualBeam Plus sonar just like the othe fish finders in the 800, 900 and 1100 series, allowing you to filter your returns by a 20° or a 60° sonic beam, observing everything passing under your boar, in a sharper or wider quality.
The navigational capabilities of the Hummingbird 858c DI Combo are also great. It has a precision external GPS which locks quite quickly. It has the built-in ContourXD package, covering over 3,000 lakes in the U.S. It also has a Navionics card slot, so you can upgrade the mapping database if you want, gaining access to the detailed Navionics or LakeMaster maps. Plus, its memory can stock up to 3,000 waypoints, 50 tracks and 50 routes.
Just like the other elite Hummingbird Fish Finders, the 858c DI Combo is Ethernet compatible.
