APM 7 x 50 Magnesium ED APO Binocular with Nitrogen Filling

If you are looking for a pair of binoculars for most any situation, look no further than the 7 x 50 ED APO model from the APM Telescopes Magnesium Series. With front objectives of 50 mm and a magnification of 7, a 7.1 mm beam of light will reach your eye, which just happens to match the maximum size that our pupils can dilate. This is not an accident! More light means more detail, especially in low light conditions, and we`re not just talking about the obvious "low-light conditions" experienced during evening hours, but the less obvious but very common problem of viewing an object in shade or shadow. Let´s look at the many features you`ll enjoy if you pick up a pair of APM ED APO 7 x 50 Binoculars:

Amazing Optics: The heart of a pair of binoculars is the optics. It doesn´t matter how beautiful they are, or how much they cost if the optics don´t give you a clear, sharp, true color image of the world around you. APM Magnesium binoculars, regardless of their magnification or aperture, use quality ED glass (FK61) and BAK-4 prisms to yield high contrast, tack-sharp images over their entire field of view. Special coatings on all optical surfaces enhance the final result producing true-to-life color.

IPX-7 Water Protection: The International Electrotechnical Commision, or IEC, classifies and rates the degree of protection provided against the intrusion of water into a system that would suffer from damage were that to happen. The APM ED APO 7 x 50 Binoculars have an IPX-7 rating, which means they are capable of withstanding water entry for up to 30 minutes in 1 meter of water. We realize this sort of mishap will most likely not happen, but this superior protection will keep your binoculars safe if they get rained on or splashed.

Rugged, Lightweight Body: APM binoculars have a body made from Magnesium, the lightest of the metal elements. Magnesium is also noted for its strength and resistance against corrosion. The binocular body is over-coated with a rubber armor, which further protects the binoculars and offers a slip-resistant grip without adding much weight. Focus is achieved by adjusting each eyepiece individually so that you can match your unique vision precisely. A tripod adapter port is located on the bridge and is covered by a metal beauty cap. To access the port, simply unscrew the cap and attach the included tripod adapter.

Good Eye Relief: The APM ED APO 7 x 50 Magnesium Series Binoculars have very comfortable eye relief of 23 mm. The term "eye relief" has to do with where your eye has to be placed to see the full image being produced. The lower the eye relief, the closer your eyes will need to be when positioned against the eyepiece. If you happen to wear eyeglasses and wish to observe with them on, eye relief becomes very important. Since APM Magnesium Binoculars have great eye relief, all you have to do if you want to wear glasses is to fold down the rubber eyecups. For non-eyeglasses wearers, keep the eyecups unfolded.

Nice Accessories: All APM Magnesium Binoculars come with a tripod adapter, a Cordura-Type soft carry case, a binocular strap, lens caps and eyepiece caps.
