KOWA 77mm Straight Spotting Scope, Prominar XD Lens (TSN-774)

Vendor: Kowa



The KOWA 77mm Straight Spotting Scope, Prominar XD Lens (TSN-774) with Angled Viewing is a scope of world-class caliber that redefines the standards of color brilliance, detail sharpness and edge-to-edge brightness.

The XD lens used in these Kowa Prominar models has characteristics similar to those of fluorite crystal to significantly reduce the chromatic aberration. These eXtra-low Dispersion (XD) glass and the lenses are made of environmentally friendly eco-glass. As with the larger models, the 774 lenses are fully multi-coated with Kowa's C3 coatings that are made of dielectric materials instead of the more common silver or aluminum.

The well established Kowa focus system has progressed to a new dual focus system. The quick focus, with a large and easy to turn knob, will focus from infinity to five meters in two revolutions. The fine focus, with smooth movements and pinpoint accuracy, is extremely useful at high magnifications and for digiscoping systems.

Kowa's standard eyepiece bayonet mount has been passed down to these new spotting scopes with a new attractive feature. An eyepiece locking mechanism has been added to the mount to prevent the eyepiece from getting lost or falling out unexpectedly.

The extremely durable housing of the Kowa 77mm Spotting Scope is constructed of strong, yet lightweight polycarbonate materials, including carbon fiber, providing a rigid structure that can endure hard usage, and has a shape and rubberized coating that is designed for ease of handling and ergonomic fit in the hand. 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 result is a compact, ergonomic, and functional design for the die-hard enthusiast that wants only the very best.
