Pentax has introduced the world’s initial three-in-one optics. The special gadget highlights optics, monocular, and telescope in a genuinely inventive plan. With a couple of snaps, the Pentax 4X20 VD WP goes from binocular to two monocular or a solitary “telescope” with an incredible 16x amplification. This “Swiss Army Knife of Binoculars” gives a 10-degree genuine field of view, which compares to 525 feet at 1,000 yards, and has a waterproof outside shield and edges that give a slip-safe grasp. The included neck lash can be changed over into two wrist ties for security. Watch the video.
