The Fujinon AIR DROP Series binocular represents an outstanding combination of advanced design and technology in terms of optics, ergonomics and control features.
It is the first series from Fujinon to incorporate the patented "G-Proof" sealed air-chamber shock absorbing system.It is the toughest binocular in the world.On key factors of U.S. Military Specifications, U.S. Military-Standard-810E(for shock, vibration, waterproof, etc.) AIR DROP binoculars exceed them.
For example, the specifications require a binocular to withstand a 40G shock test.The AIR DROP takes 200G shocks in stride....5 times greater. A binocular that can be submerged in 4.5m of water for 5mins without water penetration passes the U.S. Army Mil Spec test for being waterproof. AIR DROP binoculars pass the same test after 10mins....twice as long, twice as good. Even better AIR DROP binoculars will float when used with the supplied floatation neck strap. In drop tests, AIR DROP survives falls from heights 2-1/2 higher than the Mil Spec required.
The housings are made of space age lightweight, heavy-duty polycarbonates for exceptional durability and strength. They are sealed, dry nitrogen purged (to eliminate possible fungal growth that clouds the optics of less carefully made binoculars) and contain internal dessicants.
