Thornfield HouseKowa BD25 8x25 Compact Binoculars
Our Price: £215.00
The Kowa BD25 8x25 is a pocket binocular with a proper build. It is small enough for a jacket pocket, weighs 320g, and is waterproof, so it can come on every walk, holiday or day out.
The compact body fits in a jacket pocket or a small bag. That means it is with you when something interesting turns up, which a full-size binocular left at home never is.
Unlike many cheap compacts, the BD25 is fully waterproof, so a shower on a coastal walk is not a problem.
The Kowa BD25 8x25 has a 110m field of view at 1000m, close focus of 1.8m, 16mm eye relief and a 3.1mm exit pupil. It weighs 320g and measures 111 x 107 x 39mm.
With 16mm of eye relief, most people who wear glasses can see the whole view with the eyecups twisted down.

These binoculars suit my varied interests perfectly. The image is sharp and crisp, though the field of view isn't as wide as my regular binoculars ( 8x42 )...however it's for travelling light that I need them. Sturdily built, pocketable, lightweight. These binoculars go with me everywhere, in pockets, backpack or car. I've already observed butterflies and reptiles on local walks. Even in evening light they perform reasonably well....
