The 12-60x70 Escape Zoom Binocular from Barska is a multicoated, Porro prism binocular with BAK7 glass designed for all types of outdoor activities. The increased light gathering ability of the large objective lens translates into greater detail and image clarity which is especially useful in low light conditions or astronomical viewing. The high zoom magnification and large objective necessitate a firm and steady support and a tripod adaptor is included to alleviate the "wobbles". These binoculars are designed for convenience and ease of use. A large tactile center focus knob and an eyepiece diopter adjustment make for fast and precise focusing. They have shock-absorbing rubber armoring for a comfortable, secure and slip-free grip.
