Barska Battalion 8x30mm Porro Prism Rangefinder Binoculars Black. This binocular includes an internal range-finding reticle and features BAK-4 prisms with fully multicoated optics for maximum viewing clarity. The 8x30 Battalion Binoculars sport an individual eyepiece focusing system and attached objective lens covers. The Battalion's housing is waterproof and fogproof to ensure all-weather performance. Regardless of the climate the field-of-view will remain crystal clear while the optic's internal mechanism is well protected from the negative effects of moisture and precipitation. Outdoor enthusiasts will greatly appreciate the benefits of a comfortable ridged grip and the added shock-resistance provided by the tactile rubber armoring. Fold-down eyecups offer the user the ability to customize these binoculars to personal preference.
