This high-performance spotting scope is built with a rugged construction and high-end specifications that make it the perfect instrument of every bird watcher, hunter, or target shooter. The eye piece mounts at an angle, for the ultimate in comfort during long-term observation, especially among users of variable heights or those who are viewing high-up objects from lower-down positions like when bird watching.

Kowa's TSN-773 spotting scope is manufactured with the highest optical technology for the best-quality viewing experience, including the utilization of high-end Prominar (Apochromat) ED (extra-low dispersion) lenses that eliminate false color (chromatic aberration) for improved resolution and contrast. This scope's large, 77-millimeter diameter objective lens provides outstanding light gathering power, ensuring a bright field of view, while the sharp view and accurate color reproduction qualify the scope as a powerful instrument for observation at dawn or dusk.

The TSN-773 features lenses, prisms, and even dust protection glass on the main body all built with C3, highly-reflective, multi-layered coatings of dielectrics, ensuring clear visual range and sharp images, as well as a sliding sunshade that eliminates annoying glare in bright conditions, as well as helping keep distracting raindrops from getting to the objective lens during wetter weather.

The extremely durable housing of the Kowa TSN-773 is constructed of strong, yet lightweight magnesium, including carbon fiber, providing a rigid structure that can endure hard usage. This housing is also waterproof to JIS class 7 protection standards, and filled with dry nitrogen gas to prevent the lens from fogging, which allows this spotting scope to be used in the rain and other harsh weather conditions.

The TSN-773 spotting scope weighs 46.9 ounces, measures 12.5 inches in length, and is backed by a manufacturer's lifetime of the product warranty.
