Waterproof Binocular

Action Binoculars Nikon Nikon Action Extreme vs?

What is the difference? I think its just the fact that the extreme right is impervious from water?

There are some more differences than that. One of the main changes in eye relief. Extreme relief is 17 mm look and act just 12 mm. The difference is mainly important if you wear eye glasses. As for the water proofing of the extreme, I will not put a great deal of confidence in that ability. Porro prism binos are extremely difficult to impervious the water is my understanding. I read a complaint by a birder on a different brand porro prism binos that had to be fogproof / waterproof that failed in Costa Rica. He had to put them in the oven to their de-fog. narrow focus in both is not particularly good, but both have an excellent field see - among the best. Here is a link with a pair of Bushnell binos is waterproof to design the roof prism for the same price as the Nikon Action. Field of view is not so good, but they are lighter and have eye relief better. Http: / / www.eagleoptics.com/binoculars/bushnell/bushnell-h20-8x42-roof-prism-binocular
