Steiner 7x50 Military-Marine, Water Proof Porro Prism Binocular with 7.0° Angle of View.

The design for this binocular is based on the legendary Steiner military-issue 7 x 50, selected by the US Army and over 40 other nations. 7 x 50 optics provide excellent low-light performance and image stability. These optics, and Steiner's Sports Auto-Focus system make this the perfect binocular for boating and law enforcement applications, as well as most hunting uses. Extra-long eye relief for eyeglass wearers and comfort during extended hours of use.
