Pentax 4X20 VD WP 3-in-1 Binocular

Outfitted with a truly innovative design - the Pentax 4X20 VD WP 3-in-1 Binocular can be quickly and easily converted from a simple binocular into either two separate monoculars or - with the optical tubes stacked one in front of the other - a powerful 16x spotting scope Depending on what configuration you put the 4x20 VD in - the performance will change For example As a binocular the close focus distance is 5 feet - but as monoculars that distance drops to an impressive 20 inches The angle of view constricts from 10 degrees as a binocular or monocular to 26 degrees in spotter mode Similarly - the exit pupil is 5mm in binocular/monocular modes and drops to 125mm in spotter configuration Optically - the low magnification produces a generous 5mm exit pupil that keeps the scene in full view Dielectric and phase-correcting prism coatings work together with anti-reflection fully multicoated optics to maximize light transmission to produce bright and clear high-contrast views with accurate color and crisp resolution Twist-up helicoid rubber eyecups make using them with or without eyewear comfortable Designed for comfort and durability - the housing has exterior armor and ridges that provide a slip-resistant grip The housing is sealed to an IPX7 rating - so you can keep using it if you get caught in a sudden downpour or gets accidentally dropped in a puddle or shallow stream Since the VD WP is meant to be used by two people when configured as monoculars - the included neck strap can be converted into two wrist straps for security
