The versatile zoom feature of the Binocular Series allows the user to observe a wide field of view and then have the ability to zoom in to a subject for a more detailed look. The zoom lever allows the user to easily zoom in without taking their eyes off the subject, while a large center focus knob and eyepiece diopter adjustment make focusing quick and precise. Full rubber armor covering for a comfortable, secure and slip-free grip and provides protection against impact and shock.
