The pure fluorite crystal used in these models is the optimum optical material for reducing chromatic aberration, providing the ultimate viewing experience.

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.
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.
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.
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.
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 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.
The housing is waterproof to JIS* Protection Class 7** and filled with dry nitrogen
gas to prevent the lens from fogging. *JIS=Japanese Industrial Standard.
**The scope is not intended for use underwater.
