Steiner's Observer series of binoculars are designed to provide the versatility to match most situations under almost any condition. A choice of 2 full-sized models in a lightweight design provide comfortable ergonomics for long-term observation, bright images, crisp resolution and a wide field of view. Hardly any other binocular will get you so close with such clear, sharp detail, for so little budget. Steiner High-Contrast-Optics provide bright, accurate colours and clear images for exceptional performance right down to a close range of 2m. The 'Fast-Close-Focus' central focusing wheel requires minimal, stepless rotation for rapid sharpness from close-up to infinity. The Steiner Observer binoculars are comfortable and easy to use, with outstanding ruggedness, and feature a durable polycarbonate Makrolon construction which provides a wide working temperature range between –15 °C and 55°C. Nonslip NBR-Longlife rubber armour protection resists oil, acid and adverse weather, whilst an ergonomic design with rubber armoured controls provide comfortable and silent observation. Cylindric rotation eyecups are made of soft, skin-friendly and non-aging silicone. Lightweight roof-prism design presents less bulk for better handling.
