The 7-21x40mm zoom Binocular Series is a complete family of porro
prism binoculars designed for all types of outdoor activities. The

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.
