From the forest to the mountains to the concrete jungle, Vanguard designed the 45° angled viewing 15-45x60 VEO HD Spotting Scope to provide power and performance to new and experienced users alike for hunting, birding, and general glassing in all environments. Utilizing a generous 60mm objective lens and their Advanced MultiGuard lens coating system boosts its performance in low and challenging conditions while ensuring the views remain bright and clear, even when the magnification is dialed all the way up. Its broad zoom range allows you to enjoy a spacious 141-foot field of view and more easily scan the landscape for targets at the low 15x with the ability to quickly dial up the power to 45x and make detailed observations of distant subjects. The chassis is made of composite carbon fiber that is protected by black Mitsubishi rubber armor. Carbon fiber is corrosion resistant and lightweight; it is also resistant to thermal expansion, which can cause the optical components to move out of alignment over time. This ensures tack-sharp views for the life of the optic. The chassis is nitrogen filled and O-ring sealed to be waterproof and resistant to internal fogging even in extreme weather and temperature conditions. The angled-viewing configuration sets the eyepiece at a 45° angle to the scope's body, which places your head in a more comfortable viewing position versus straight-through viewing models, and the whole body can be rotated relative to the tripod mount for perfect eyepiece placement. A 1/4"-20 mount makes it compatible with many tripods, quick release plates, and other popular support systems like window mounts.
