Barr & Stroud Sierra 12x50 Phase coated

Product description

Sturdy binoculars for any weather
The Barr & Stroud Sierra 12x50 are waterproof binoculars that come unharmed from a fall into a water up to 1.5 meters deep for no longer then 3 minutes. This pair of binoculars is very sturdy and can be used in any weather conditions. The housing is filled with nitrogen, which protects the lenses from corroding and from fogging-up quickly in the event of large temperature fluctuations. In addition, the rugged polycarbonate housing and the surrounding rubber coating make these binoculars very robust and resistant. 

Great magnification
The Barr & Stroud Sierra 12x50 has a lens diameter of 50 millimeters and a magnification of 12x. Because of the high magnification you will suffer from some loss of light, but in return you can get very good quality images from very far. The width of the field of view is 82 meters (on 1000 m), giving you quite brought view even from a long distance. In addition the eyepiece has a diopter adjustment and can be put on strength of +4 to -4. 

Some extras
Thanks to the metal twist-up eyecups Barr & Stroud Sierra 12x50 binoculars are also suitable for eyeglass wearers. Moreover, in the front of the bridge there is a tripod connection. This means that with a help of a tripod adapter, you would be able to place the binoculars on a tripod for more stable observations.
