Furuno’s RotoKey interface allows for simple and stress-free operation. Turn the RotoKey for a finely stepped zoom control, or press the knob for full access to the GP1870F controls. The LCD screen allows for viewing from virtually any angle, even while wearing polarised sunglasses, plus the screen is bonded to ensure fogging-free operation.


Bottom Discrimination

Whether fishing, diving, navigating or anchoring, knowing bottom type is a major advantage for virtually any boater. The advanced signal processing of the GP1870F's Fish Finder provides a graphical display of the water column and objects in the water, in addition to showing composition of the seafloor. When connected to an appropriate transducer, the Bottom Discrimination feature provides a graphical display showing the characteristics of the seafloor as either mud, sand, gravel or rock. Amazingly, it can also show a bottom type probability curve when boating in an area with mixed bottom composition.


The Accu-Fish feature is a revolutionary fish size assessment function that can tell you the approximate size of the fish below your boat. Fish symbols appear on the screen, along with the size of the fish or the depth where it found the fish. It can detect fish size from 4 inches up to about 6 feet long, in depths of 7 feet to well over 300 feet of water. Accu-Fish signal processing blends the high and low frequencies to depict fish targets of all types simply, clearly and distinctly. Now, fishermen can clearly and easily distinguish big billfish around a bait ball, or see through bait and trash fish on the surface totarget "the big one" below.
