Vanguard Spirit 8x42 Binoculars

So what makes these binoculars so special?
 
Its an accumulation of several factors, It's the culmination of years of research and development that have been invested into both the optical quality and the advanced optical design of binoculars that combined with the latest materials result in a binocular that is truly at the cutting edge of design and technology and is a milestone the development of the Vanguard range of optics.
 
Lets look at the optical design which represents a major step forward in binocular design. The Spirit's stunning optical performance has been achieved using one less optical component than traditional designs. This means there are less glass surfaces to refract light which makes them brighter by design. Combine this with Bak-4 prisms the latest phase coating techniques and 'HydroGuard' technology and you really can these binoculars are special as soon as you put them to your eyes.
 
The binoculars are incredibly lightweight. This is as a result of Vanguard using the latest engineering polymer material, a product of space technology, for the construction of the body of the Spirit binoculars, making them strong but not at the expense of weight. In addition the binoculars are nitrogen filled making them waterproof and resistant to internal fogging in extreme weather and temperature conditions. These binoculars are so tough that Vanguard are prepared to guarantee them for the lifetime of the purchaser - you just cant do better than that!
