Kowa TSN 880 Series Spotting Scopes, TSN 881, TSN 882, TSN 883, TSN 884, Straight, Angled

Large Lens, Compact Size
The telephoto lens design of using 5 lens elements in 4 groups has successfully shortened the overall length of the scope while keeping a large diameter objective lens without sacrificing optical performance. The adoption of an inner focusing system has made the prism box light and compact and at the same time decreases the amount of image movement when compared to conventional prism focusing systems. The highly achromatized objective lens makes the scope as compact as a 60mm class scope without sacrificing performance.

Advanced design
This body, designed to be user-friendly, is light and compact despite its large objective lens and metal construction. Logically tailored to meet the needs of the most demanding user, every technical and ergonomic detail has been painstakingly examined and perfected. Users of these advanced spotting scopes will know that they possess an instrument of extremely high quality.

	Magnesium alloy body The magnesium alloy body made by a sophisticated molding process called thixotropic molding has the feel and strength of a traditional metal body with decreased weight when compared to other large-diameter scopes. The rugged structure can tolerate the severest conditions and provides confidence and a sense of security for the user.
	Dual focus mechanism 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 movement and pinpoint accuracy, is extremely useful at high magnifications and for digiscoping systems.
	Eyepiece locking mechanism 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.
	Tripod mount The addition of a brass insert to the tripod mount of the scope allows the scope to be secured to both 1/4 and 3/8 inch mount tripods.
Compact size The adoption of the inner focus system keeps the prism box light and compact, realizing a large 77mm objective lens in a body length of a 60mm class scope.
Waterproof and filled with dry nitrogen gas The housing is waterproof to JIS Protection Class 7 and filled with dry nitrogen gas to prevent the lens from fogging.
