With antireflection, high-definition lenses delivering sharp, clear images by day or night, the 7x50 Commander Marine Binoculars from Steiner are a mainstay of the maritime world. The configuration of 7x magnifying power, 50mm objective lenses, and individual, one-time focus is a proven favorite on the water, where excessive magnification and focusing only get in the way. Open-bridge design makes the binoculars easy to grip, and foldable winged eyecups keep lateral light out of your eyes.
For extra protection against dirt, oil, and water, Steiner treated the objectives and oculars with a hydrophobic coating that resists scratches and makes cleaning the lenses easier without residue. The chassis is made of lightweight and impact-resistant polycarbonate that is wrapped in an NBR synthetic rubber armor that is oil, petroleu, and chemical resistant. The optical tubes are nitrogen-filled and O-ring sealed to be waterproof to a depth of 33 feet, and resistant to internal fogging when moving through extreme temperature changes and environmental conditions.
- 7x power provides moderate magnification while helping to produce a wide exit pupil for easier low-light use, without sacrificing field of view
- Large 50mm objective lens diameter admits ample light for a brighter image at dawn and dusk, or in dense fog
- Traditional Porro prism design makes it comfortable to hold, and presents a rich depth of field
- Diamond marine coating maximizes light transmission and color rendition across the entire visible spectrum, with improved contrast and clarity
- Proprietary Nano-Protection protects lens surfaces enabling water to bead off, and preventing dirt from sticking, to provide clearer views in all weather conditions
- Individually-focusing eyepieces enable highly-precise focusing, with memory diopter system to store and indicate personal diopter setting
- Fold-down rubber eyecups for comfortable use with or without eyewear
- Large 7.1mm exit pupil is optimized for low-light conditions to completely cover pupils when they are fully dilated to avoid vignetting of the view
- Lightweight polycarbonate chassis is corrosion and impact resistant
- Nitrogen-filled and O-ring sealed to be waterproof to a depth of 33' and resistant to internal fogging when moving through extreme temperature changes and environmental conditions
- ErgoFlex winged angled eyecups block stray peripheral light from interfering with views while improving contrast and limiting distractions
- NBR synthetic rubber armor is oil, petroleum, and chemical resistant to offer improved grip security, especially in cold and wet weather
- Includes a buoyant high-visibility yellow neck strap; outfitted with fast attachment/detach ClicLoc system
