Tonu from estonia - Nikon Action Extreme 10x50mm Waterproof Porro Prism Binocular

I purchased binoculars ssome month ago.It is good tool and satisfies my expectations. Just only one improvement should be done. the twist out eyecup design should be tighter and not move so easily.
If I need to look quickly into binocular during hunting the eyecups are moving in and my previous good visibility is lost. Also one eyecup was game off when I tried rapidly remove the cover and small balls guiding the gap were lost. I fixed the problem with installing new balls from one very small ball-bearing that I found. This solves also my problem of easy-moving and I changed also guiding balls in other eyecup.
Now binocular working perfect

Pros: good clear picture
Cons: twist out eyecups moving too easy
