The 7-21x40mm zoom Binocular Series is a complete family of porro prism binoculars designed for all types of outdoor activities. The increased light gathering ability of their large objective lens translates into greater detail and image clarity which is especially useful in low light conditions and at night. 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.
