The legendary XD lenses used in these binoculars are not just any ED glass. The glass featured is high resolution extra low dispersion glass containing large amounts of the mineral fluorite crystal. Fluorite crystal is the best material available to optical makers offering unchallenged light transmission, edge to edge definition and zero chromatic aberration. All these offer a sharp, high contrast image most other optics in this price range simply can not offer.
The BD II series now offer some series optical features besides the XD glass. The first is the amazing wide angle performance through the whole range. The highlight model would be the new addition to the BD family, the 6.5×32. The field of view from these new optics is 10 degrees or 175m at 1000m. The 6.5×32 also offers a close focus distance of just 1.3m, good enough to see the laces on your shoes. Combining these features, as well as weighing just 535g, means the 6.5x model is perfect for butterflies, insects, dragon flies and even flowers.
The regular 8×32 and 10×32 models offer a very good field of view at 8.8 and 6.7 degrees respectively along with the incredible 1.3m close focusing. The popular 8×42 setup will give you 8.2 degrees, 1.8m close focus and weighing in at 640g.
Each binocular has a rugged and lightweight magnesium alloy construction. They can tolerate the severst conditions whilst providing the user security and comfort in use.
The dry nitrogen use in the binoculars will prevent the binoculars from fogging and keep the binoculars fully water proof. The KR coating on the external side of the lenses will protect them from dirt and other types of residue that build-up over general use.
