National Geographic 4x21 Rangefinder The rangefinder determines, via a laser harmless to the human eye, the exact range of the object aimed at, up to 800 metres away, within seconds. The result can be displayed in metres or yards. The compact dimensions, the very low weight and the easy-to-use operation makes the range finder a perfect companion for hiking, hunting, at sea, in the stadium or other outdoor activities.
