Sahara 8x42 Roof Prism Binoculars
The Barr & Stroud Sahara 8x42 is a rugged go anywhere binocular. Equally at home on Lake Naivasha, the beach at Bridlington or a day at the races.
This is a compact roof prism design that makes an ideal all round performer with good light gathering ability. The binocular focuses down to just under 2m making it ideal for naturalists and birdwatchers alike. The binocular delivers a powerful 8x magnification.
The Sahara range from Barr & Stroud feature rugged construction combined with brilliant optics. They are waterproof to a depth 1.5m of water for three minutes, plenty of time to retrieve them if you have dropped them in a stream or puddle. This requires a high degree of mechanical quality in the construction of the binocular which is evident as soon as you pick the binocular up or use the super smooth focus control wheel. We dont expect that you will make a habit of dropping the binoculars into deep water but we do expect that you will want to use them in any weather the planet can throw at you, so you can feel assured that the Barr & Stroud Sahara can take it, again and again. This ability is further enhanced by the binoculars rubber armoured body which protects it from shocks and knocks.
The binoculars are filled with nitrogen gas which keeps water out and also stops the optics suffering from internal fogging in adverse weather conditions.
Fully Multi Coated optics are standard features of the Barr & Stroud Sahara range as are BaK-4 prisms. This ensures that as much light as possible is transmitted through the optics which results in a super bright contrast rich images for the user even in low light conditions where less expensive optics and coatings result in a dramatic loss of performance.
For the comfort of the user the binoculars are supplied with twist up rubber eyecups which make them equally practical for people to use with or without spectacles.
The rapid focus mechanism takes the user from close focus to infinity in less than one turn of the focus control knob, which ensures that you can follow the action however fast it is happening.
The Sahara 8x42 are supplied with carrying case, rain guards, tethered lens caps, straps and lens
