Bushnell H2O 10x42 Porro
Bushnell H2O 10x42 Porro is part of the H2O series. With this series Bushnell have created a viewer that is completely waterproof and that can be used in wetland situations, for example during kayaking, skiing, boating or on the snowmobile. Even when the viewer falls overboard you can fish it out of the water unaffected. The coating consists of extra strong rubber and has a ribbed surface on the side for extra grip, very useful in extremely wet conditions. The front lenses are multi-coated for optimum light transmission and are made of BaK4 glass (the better version of BK7 glass). The H2O series includes a wide range of models; please browse around on our site to look for the model that suits you best. In short, the H2O is a wonderful series of viewers for a spectacular view during all your adventures.

H2O Porro or Roof?
H2O 10x42 is available in two versions, Porro and Roof. Porro binoculars (see diagram below) are broader binoculars and based on the first design of binoculars. The Porro consists of two rectangular prisms attached together so that the light is reflected, resulting in a correct image. The conventional binoculars use Porro Prisms.
A Roof viewer uses special prisms. This design is technically more complicated than a Porro prism design, because it uses prisms which must have very accurately polished edges. The light is reflected four times. This design is more compact, but because the path of light is longer and the prisms more complicated, the glass and the manufacturing must be of a higher quality than that of the Porro Prism design. This is why roof viewers generally have a higher price tag. Roof prism binoculars have straight tubes as shown in the picture.
