Product Reviews

Collected via Trustpilot 5 star review

I know what good optics should be like Ive had the best in the world but had to sell them a few years ago while going through a divorce. Slowly Im getting my optics back I just couldnt afford the best scope in the world this time around so I went for next best thing Kowa. When I looked through it for the first time I was blown away by the quality of the optics. Bright tac sharp true to colour. I honestly can not tell the difference in this scope and so called the best in the world. I was counting the feathers on starlings 100 yards away. Build quality very good but not the best optically is definitely among the best. Fantastic scope Im well happy with it.

The best scope in its price range easy to use and fantastic optics although in lower light I would recommend the 30x wide angle lens.
