The Monovid features nitrogen filling to prevent internal fogging and water and dirt repellent AquaDura® coating on all exposed lens surfaces. Furthermore, in contrast to other monoculars, it is not only water-resistant, but fully waterproof to a depth of 5 m (16.5 ft). It is extremely handy and versatile and is the featherweight of its class at only 112 g / 3.95 oz. It slips comfortably into any jacket pocket and is a constantly ready and able companion. Particularly practical: when not in use, its close-up lens can be stored safely in the leather case provided. The best place to keep it safe and sound; screwed tight, so it can’t be lost. Yet another advantage is the silent magnetic clasp of its refined and elegant tubular case.
