This 7x binocular with high light-gathering power is primarily designed for extreme viewing conditions. Its special characteristics: a 8 mm exit pupil and a very large and super-bright field of view of 150 m at 1000 m (150 yds. at 1000 yds.). They let you keep fast-moving subjects firmly in sight, even under difficult light conditions. Another plus: with the TRINOVID 7 x 35 you can keep everything well in sight, even when your hands are not as steady as usual for instance after a strenuous hike. Because of its high light-gathering power, this binocular offers a bright image well into dusk.
