Since MarCum released its first underwater video camera with a monitor for fishing, an entire generation of anglers has benefitted from eyes below the lake surface.  Their world has been forever changed because of it, from the way modern ice anglers fish to the equipment they use, underwater viewing has shaped the evolution of the sport.  These MarCum underwater cameras can be used for ice fishing, freshwater, and saltwater fishing, and while the systems themselves have also evolved through the years, the one thing that remains consistent over time is the amount of information anglers glean when seeing underwater for the first time.
