Optimised for viewing across extended distances, the Hawke Endurance ED 15-45x60 Spotting Scope for 45-degree angled viewing features premium-quality glass with specialised optical coatings. It provides you with crisp and high-resolution images throughout the magnification range. It features a twist-up eyecup for proper, stable eye relief. The eyecup can be used at any position for enhanced comfort. It also features a dual-focus knob for fast coarse and precision fine focusing, making it easy to find and view moving or multiple subjects. It comes fitted with an adjustable mounting foot that can be rotated in any position in a range of about 180° for added convenience. The built-in twist-out sunshade stops unwanted reflections such as glare and lens flare, which can ruin the viewing image. Designed to be travel-friendly, it is waterproof, nitrogen purged, and fog proof to withstand extreme changes in temperature and environmental conditions.
