Details: The angled view Endeavor HD spotting scope combines a nitrogen-filled magnesium housing and a fully multi-coated optical system to create a well-equipped zoom scope for intermediate to long-range observation. The optical system employs extra-low dispersion glass (ED) to ensure accurate color rendition and virtually eliminate color fringing. The lenses are fully multi-coated to ensure optimum light transmission and feature a phase-coated BAK4 roof prism. It also provides a very impressive field of view.   In addition to the image quality and weather-sealed construction, the Endeavor HD includes several features that enhance the scope s functionality. It features an extendable rubber covered eyecup and boasts impressive eye relief even at the highest zoom settings. A built-in sunshield is included to eliminate glare in direct sunlight and it includes a padded raincoat with sling for carry and protection. Endeavor HD is also equipped with fine and coarse focusing wheels for quick and precision fine tuning adjustments. The Endeavor HD mounts directly to Vanguard tripod heads (and others) that are equipped with the universal mounting plate without the use of a quick shoe.
