Thornfield HouseKowa BD25 10x25 Compact Binoculars
Our Price: £225.00
The Kowa BD25 10x25 gives 10x magnification in a compact body that weighs 320g. Its 18mm eye relief is unusually long for a compact, so it is one of the few pocket 10x binoculars that works well for people who wear glasses.
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 10x25 has an 87m field of view at 1000m, close focus of 1.8m, 18mm eye relief and a 2.5mm exit pupil. It weighs 320g and measures 111 x 107 x 39mm.
With 18mm of eye relief, most people who wear glasses can see the whole view with the eyecups twisted down.
