Paradoxically this latest model from Barr and Stroud is the model that most resembles the most famous Barr & Stroud models from the past. This is largely a result of the modern Open Bridge design. The Open Bridge has a number of advantages over the more traditional designs currently available. The most obvious is the ease of handling that this design allows; ergonomically it is a perfect fit with the human hand. This makes it easy and comfortable to use in the most gruelling circumstances and particularly with gloved hands. 

A less obvious advantage, but one that will please many users, is the amount of weight that is saved by the Open Bridge design, this makes the Series 4 particularly suitable to those who are constrained by the amount of weight they are carrying, hikers, walkers, holidaymakers or service personnel are but a few of those who will appreciate the ease of handling and comparative lightness of the Series 4. 

The Series 4 range from Barr & Stroud feature rugged construction combined with brilliant optics and high resolution eyepieces to produces stunning images. 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 engineering excellence in the construction of the binocular which is evident as soon as you pick it up or use the super smooth focus control wheel. 

We don't 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 Series 4 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, this binocular is truly weatherproof. 

Fully Multi Coated optics are standard features of the Barr & Stroud Series 4 range as are BaK-4 phase coated prisms. This degree of sophistication ensures that as much light as possible is transmitted through the optics which results in super bright contrast rich images of high colour fidelity 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 metal twist up eyecups that are rubber coated 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 Series 4 10x42 is supplied with carrying case, rain guards, tethered lens caps, deluxe strap and lens cleaning cloth.
