Swarovski CL Companion 10x30 Overview

With phase-corrected roof prisms and enhanced optical coatings, Swarovski's green 10x30 CL Companion Binocular delivers high-contrast images with accurate true-to-life color and virtually zero distortion across the entire field of view. Styled and engineered with an ergonomic profile, a non-slip focusing wheel, and individually adjustable twist-in eyecups, they offer a comfortable viewing experience for long observation sessions. This version of the Companion includes a standard field bag, shoulder strap and wrist strap in addition to two objective lens covers and an eyepiece rainguard.

Swarovski's SWAROBRIGHT phase-correcting coatings applied to their premium roof prisms eliminate color fringing and aberrations for enhanced color fidelity and contrast, while their SWAROTOP coating on the other optical surfaces enhance light transmission and viewing accuracy. The outer lens surfaces are further coated with Swarovski's SWARODUR which improves scratch-resistance and allows oils, saps, and water to bead off which not only helps to keep the surfaces clear, it makes cleaning them easier.

The CL Companions utilize a compact and thin bridge construction with thumb depressions on the underside of the binoculars for steady, balanced viewing comfort. This trim form-factor is relatively light and small enough to pack and travel with ease. Its green non-slip full rubber armoring provides shock resistance, the the optical tubes are nitrogen filled to prevent internal fogging and makes them submersible to 13 feet.
