Steiner has developed a compact, Roof Prism Tactical Binocular incorporating the SUMR targeting, reticle system. The Steiner 10x42 R Tactical Binocular featires a new optical system formulation, multi-coated optics and a shock and nitrogen pressurized waterproof housing. Its Mil Reticle Targeting System allows faster and more accurate communications between the spotter/observer and weapons delivery personnel.
The reticle is based on the standard Mil Radian System, and its mil graduations combine standard 5 and 10 mil increments that reduce down to single and split mils towards the center of the view area enabling the user to effectively accomplish observation, control and coordination of small arms fire.
