The Pentax 4x20 VD WP is a unique 3-in-1 binocular that can split into 2 monoculars, which can also be joined into a single, more powerful monocular.
The left and right barrels separate from the center, and each can be used as an individual monocular. Enjoy gazing at far-off scenery together to share the same sense of excitement. Enjoy in three ways that suit your purpose and the scene (binoculars, monoculars, telescope). All of these are in this single item. These high-performance three-in-one binoculars are only possible with an optical manufacturer.
The 4X magnification is convenient for watching stage performances, concerts, and sporting events. They feature the right field of view for scenes with movement and for situations where you want to view the entire scene.
When 4X magnification is not enough for viewing stars or far-away scenery, connect each monocular's end to make a 16X telescope.
Superb optical performance
Full multi-coating is used on the surface of all lenses and prisms to prevent the reflection of unwanted light. Also, phase-coated roof-prisms and super-high-reflection dielectric multi-layer coating on the auxiliary prism provides dramatic improvements in light transmission, reducing flare and ghosting, and delivering bright, sharp, high-contrast optical performance.
Washable waterproof performance
The waterproof construction* (equivalent to JIS Class 7; protected against immersion to one meter under the water) makes it possible to wash these binoculars and use them in any weather. With this construction, you can use them in the rain, near waterfalls, and in other outdoor activities.
