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° as a binocular or monocular to 2.6° in spotter mode.
  • Similarly, the exit pupil is 5mm in binocular/monocular modes and drops to 1.25mm 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.
