The 10x50 Escape Zoom Binocular from Barska is a multicoated, Porro prism binocular with BAK7 glass designed for all types of outdoor activities. The 50 mm objective increases the light gathering ability of the binocular which translates into greater detail and sharper image clarity, attributes which are especially useful in low light conditions or distance viewing. A threaded mount receptacle has been designed into the housing to allow an adaptor to be attached to the binocular for use with a tripod or window mount. These binoculars are designed for convenience and ease of use. A large tactile center focus knob makes for fast and precise focusing. An eyepiece diopter adjustment allows customization for each individual eye affording less eyestrain over long-term viewing. They have shock-absorbing rubber armoring for a comfortable, secure and slip-free grip.
