The Military R series sets the standards for durability and performance. It features Steiner's revolutionary Sports Auto Focus system, which once set to the user's individual eyesight allows observations from 60' (18.3 m) to infinity without the need for focus readjustment. The 10x50 is the best pick for high magnification with the exceptional lowlight performance from Steiner's wonderful military-specification optical coatings.

Comments about Steiner 10x50 Military R SUMR Binocular:
I bought these to use while finishing my deployment in Afghanistan and then to use at home on wild land fires as well as on SAR operations with my hometown fire department. These bino's have proven to be the best bino's I have ever used. The SUMR is very clear and easy to utilize when calculating distances. They have proven to be very durable after a drop off the top of an MRAP onto some gravel with no serious damage. I have very little limitations on how far I can see with excellent clarity even in very low light environments. I would recommend these to anyone who is in need to have minimal visual limitations in most environments. Great for looking into the night sky also.
