The Opticron Universal Smartphone Mount USM-2 is a practical and reliable solution for anyone looking to capture high-quality photos or videos through their spotting scope or binoculars. Designed to offer both simplicity and stability, it allows you to position your smartphone securely over an eyepiece, giving you an effortless way to document wildlife, scenery or sporting events with greater detail and clarity.
Built with a 4-clamp adjustable mounting plate, the USM-2 holds your phone firmly in place and is compatible with devices up to 6.5 inches in screen size. On the eyepiece side, a self-centring 3-pin adjustable clamp ensures a precise and stable fit over viewing eyepieces ranging from 31–55mm in diameter. This intuitive setup makes alignment quick and straightforward, even when switching between optics.
Despite its robust construction, the mount remains lightweight at just 160g, combining aluminium alloy, plastic and rubber for durability without unnecessary bulk. Finished in black for a sleek, unobtrusive appearance, the USM-2 measures 150×90×55mm, making it compact enough to accompany you on any outdoor adventure. It is also waterproof, adding peace of mind in unpredictable weather.
The USM-2 comes supplied with foam pads for additional grip and protection, and it is backed by a two-year guarantee, underscoring Opticron’s commitment to quality.
