The Commander XP 7x30 Binocular from Steiner was engineered for the boating enthusiast. The mariner will find this superior optic an essential piece of equipment anywhere she finds herself within the wide world of the seas, lakes and rivers. This binocular was designed and engineered with the hydrosphere in mind. Sturdy, waterproof construction down to 10m is achieved via special sealing technologies that also keep out the dust, dirt and humidity. And, a floating neck strap is included to make sure the glass doesn't sink if accidently dropped. Fog-free viewing and moisture protected performance are furnished by the two-valve system of dry nitrogen pressure filling, while NBR-Longlife rubber armoring makes the housing rugged, shock resistant and slip-proof. The 7x magnification with a 30mm objective effectively provides a binocular that can be leveraged in any situation. Individual eye Sports-Auto-Focus with diopter adjustment and soft silicone cylindrical eyecups allows comfort and customized viewing. This binocular lives up to the standards of excellence that the Steiner name has come to imply.
