Fishing enthusiasts who wonder why the fish aren’t biting could do with a little help from the Humminbird 997c SI Combo GPS unit. This won’t work for those who sit motionless on a rock underneath a shaded tree of course, as it is meant to be used on a boat. The 800MHz scanner is capable of forming detailed maps of the sea floor up to 150 feet directly below a boat or up to 240 feet on either side. The 8″ display is also generous enough to display live marine chart data side-by-side with the maps. Dual SD memory card slots allow for extra maps and image storage purposes, where the 16-channel GPS receiver offers unprecedented accuracy. The Humminbird 997c SI Combo GPS unit retails for $1,999 and comes with a detailed UniMap chart.
