Steiner is building its new compact 27-ounce, 10x42 Roof Prism, Police Binocular to include rugged, shockproof, and waterproof integrity, and fully multicoated optics and phase corrected roof prisms that produce optimum resolution, brightness, and color reproduction. The 10x42 binocular is compact and comfortable to use. It’s also durable, with a sturdy frame carriage and housing made of strong yet lightweight Makrolon. The housing also uses aircraft-grade aluminum and is covered with a slip-proof, non-reflective, black rubber armoring.
