Steiner Military-Marine 10×50 Binoculars

The Steiner Optics Military-Marine 10x50 binoculars are a civilian adaptation of Steiner's proven military design, built for rugged, all‑around use. They combine 10x magnification with 50 mm objectives to provide bright images and a wide field of view in open terrain and low-light conditions. The Sports-Auto-Focus system maintains sharp images from 20 yards to infinity after a single eyepiece adjustment, and the floating prism system absorbs severe shock to protect optical alignment. Makrolon housing with NBR Long Life rubber armoring adds a lightweight, impact-resistant chassis suitable for demanding outdoor environments.
