All-metal chassis, Nitrogen filledThe all-metal chassis ensures ruggedness and durability in the harshest elements, meaning the chassis won't crack in the extreme cold of winter, or disform in the intense heat of summer. Moreover, the chassis is filled with high-purity dry nitrogen gas to prevent internal fogging of lenses, protect the binoculars from water, and then to withstand all-weather environment.
Premium BaK4 PrismThe prisms inside the Desert Birding/Stargazing Binoculars are made of high quality BaK-4 glass, phase coated, so that more light is reflected off their internal faces and passes through to the eye. Taken together, the fully multi-coated lenses and BaK-4 prisms maximize light transmission for the remarkably bright, highly detailed images.
50mm objective lensesAllowing more lights coming into the binoculars, and thus producing brighter and clearer images.
Powerful 15x MagnificationPowerful binoculars with 15x magnification, to get the detail you need when observing nature or the sky. High power increasing the reality 15 times. Find more details on the moon, see what others can't!
Fully-coated Super HD Optical Glasses
Super HD Optical lens glasses minimize the chromatic dispersion and aberrations. Moreover, all air-to-glass surfaces on the Desert Hunting/ Birding Binoculars are coated with anti-reflectivity coatings so that the maximum amount of light passes through the glass to the eyes and true colors can be revealed.
