The Bushnell 10x50 PowerView Binocular is a lightweight, compact, durable and ergonomic design for maximum comfort. It has the power and light-gathering ability that make this an effective optic for use from the pre-dawn hours through the evening twilight. The optical surfaces are multi-coated to improve colour and contrast and maximize light transmission. A large center focusing wheel and right-eye dioptric correction allows most users to focus the PowerView to their specific prescription. The twist-up rubber eyecups enable comfortable use with or without eyewear. With the higher magnification and large objectives, hand-holding this optic for prolonged periods may cause fatigue and visible hand-shake, so it can be tripod mounted with an optional adapter.
