About Nikon 7442 If Sports/Marine Porro Prism Binocular
FEATURED REVIEWS
Pleasing piece of gear
This is a very nice pair of binoculars. Not as exciting as the ProStar model, but the cost is less than 1/3rd of the Prostar. This binocular is very functional, and well designed, and I love the independend tocus. The eyepieces focus smoothly with proper amount of resistance. Well, when it comes to the strap though, I think I am going to use the strap form my Prostar or Astroluxe. But aside from the strangly thin strap, which I didn't even bother to put on, this binocular is perfect. A...

The Nikon 7x50 IF Sports & Marine series includes standard and compass models, both totally waterproof, fogproof and shock resistant to survive in the harsh marine environment.
Nikon chose individual focus for the 7x50's eyepieces to eliminate the need for constant focusing when most viewing is at longer distances. Each ocular lens is focused to meet the requirements of the user's eyes, then no further focusing is required. If lent to a mate, the skipper can return the focus to his own settings quickly and easily.
The optimum ratio between magnification (7X) and objective lens (50mm) delivers an exit pupil of more than the 7mm that will satisfactorily accommodate the human eye during very low light conditions. The result is maximum light gathering at dawn, dusk or fog when navigation markers must not only be seen, but identified for safe piloting in coastal waters, harbors and inlets. The 7X magnification is the power of choice by mariners for steady viewing on the water.
The difference between these glasses and those of lesser quality, Nikon said, is in the optics, for which the company is renowned, and a superb mechanical system that keeps lens perfectly parallel for constant viewing without eye fatigue.
The lens surfaces have Nikon's unsurpassed multi-layered, anti-reflection coatings to transmit the highest possible percentage of ambient light.
Because Nikon's 7x50 IF binoculars were designed for the worst possible combinations of wind, rain, salt spray and even green water cascading over the bow, they were made totally waterproof and totally fogproof.
In the manufacturing process, the Nikon 7x50 IFs are purged of air and moisture, filled with dry nitrogen gas and sealed securely with O-rings. This process guarantees the glasses will never leak nor fog-up even in extreme changes of temperature and humidity. Nikon said the 7x50 IFs are even totally immersion-proof so they can be used in any sea and weather conditions.
The Porro prism binoculars also are rubber armored to make them shock resistant and right at home on the bridge or wheelhouse of a vessel pitching through rough seas. The rubber armor makes these glasses easy to grip, and keeps them from sliding on slick fiberglass surfaces.
