Kowa BD25-10 overview

  • 1Description

The lightweight and compact Kowa 10x25 BD25-10 Binocular is intended for hikers, birders, and outdoor enthusiasts, with performance-enhancing features that include phase-corrected prisms with highly-reflective C3 coatings and fully multi-coated optics to produce bright and crisp high-contrast views with accurate color fidelity. A short 6' close focus makes it ideal for enjoying detailed observations of small subjects like feeding hummingbirds, butterflies, or insects. The housing is nitrogen-filled to make the binocular fully waterproof and prevent fogging when moving through extreme temperature changes. The combination of compact form factor and lightweight design make the BD25 easy to carry in a pocket, pack, or bag without adding bulk or heft to your load so you can carry them with confidence that you'll never miss a glassing opportunity on the trail, in the field, or at the stadium.

    Kowa BD25-10 reviews

    10x25 BD25-10 Binocular (Green) is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Perfect for travel I have 2 bins - the Kowa 10x25 BD25-10 and the Celestron 9x33. Both are excellent but the size and weight of the Kowa are perfect for traveling and I cannot tell the difference in clarity. Plan to take both on a safari but the Kowa will probably be used more - certainly moe by by wife
