Binoculars & scopes

A pair of binoculars is really only a simple device: it helps to view a subject a bit better then with your own eyes. But why are there so many models and such large price differences? It turns out to be a bit more complicated than meets the eye.


The specifications of binoculars contain a lot of numbers and concepts. What is important and what do you look for? We are trying not only to sell good binoculars, but also to provide as much information as possible. This decreases the chance of you ending up with binoculars you don't like. That is why we have listed the main concepts.
