The 10-30x60 Escape Zoom Binocular from Barska has multicoated BAK7 optics in a traditional Porro prism design. A larger 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. The combination of high zoom magnification with a large objective lens necessitates a firm and steady support. Consequently, 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. 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. This binocular is designed for convenience and ease of use.
