Amazing Optics: With any pair of binoculars, the heart is certainly the optics. The APM 10 x 50 Magnesium Binoculars use high quality ED Glass (FK61) and BAK-4 Prisms to give you intensely sharp image quality with high contrast across your entire field of view. Special coatings on every one of its optical surfaces work to enhance the final resulting view, producing a superb true to life color. Focus is achieved by adjusting each eyepiece individually, assuring that you are able to match your own vision precisely!

IPX-7 Water Protection: The APM ED APO 10 x 50 Magnesium Binoculars have an IPX-7 rating, as given by the International Electrotechnical Commission. The IEC classifies and rates the degree of protection provided against the intrusion of water into a system, given that the introduction of water could adversely affect and damage said product. With the IPX-7 rating, the APM ED APO 10 x 50 Binoculars are capable of withstanding water entry for up to 30 minutes in 1 meter (just over 3 feet) of water. Even in sudden bouts of rain, or splashing, your APM Binoculars will be safe and protected!

Rugged & Light Body The APM 10 x 50 Binoculars are made from Magnesium, known for not only being the lightest of metal elements, but also one of the strongest with resistance against corrosion. The body of the binoculars is coated with rubber, giving you further protection along with a slip resistant grip; all without adding to its weight!

Eye Relief: With an eye relief of 23 mm, you are sure to find comfort with these binoculars. Eye Relief refers to where your eye needs to be placed to see the full image being produced.

Solid lightweight case: APM binoculars have a magnesium housing, the lightest of the metals. Magnesium is still known for its strength and resistance to corrosion. The binoculars are also covered with a rubber coating that further protects the binoculars and allows a secure, non-slip grip without weighing too much. The focus is adjusted by individually focusing each eyepiece individually. A tripod adapter connector is attached to the front of the bridge and covered with a nice metal cap. To access the port, all you need to do is unscrew the cap and attach the attached tripod adapter. 

Large pupillary distance:
The APM 10 x 50 mg ED APO binoculars have a very comfortable pupillary distance of 20 mm. The term pupillary distance explains where to place your eye to see the entire field of view. The smaller this distance, the closer you need to bring your eye closer to the eyepiece. If you wear glasses and want to watch with them, this distance becomes very important. Since the APM binoculars have a large pupillary distance, if you want to observe with a pair of glasses, you only have to fold in the eye-cups. For normal observation without glasses, the eye-cups remain unfolded. 

Other accessories: All APM binoculars come with a tripod adapter, a Cordura carrying case, a shoulder strap, lens caps and eyepiece caps.
