The Ultimate Spotting Scope
Kowa's Top Spotting Scopes
Digiscoping Additions

Kowa Authorized Dealer It's the big objective lens-indeed, the "eye" of the Kowa Prominar Spotting Scope that sets it apart from the competition. For birders and hunters alike, these are the scopes that re-define clarity, because - among their other impressive features - they boast large 77mm eXtra-low Dispersion objective lens crafted of fully multi-coated optics. Ensuring maximum light gathering, clear visual range and sharp images that traditional glass lenses can not attain in the field.

Fluorite has an outstanding feature of very low dispersion that cannot be found in optical glass. This characteristic enables Kowa scopes to almost completely eliminate color blur. The richness and clarity of these new scopes set a whole new standard for the very top end optics.


Kowa's Optical Coatings are of a new proprietary design and provide light transmission of 99% or higher across the entire visible spectrum. Not only does this provide bright and sharp images, but accurate color reproduction is also achieved.

The magnesium alloy body makes the scopes very rugged and light weight. Their compact size makes them easy to carry and handle. The waterproof housing meets the rigorous standards of JIS Protection Class 7 and they are charged with dry nitrogen gas to prevent fogging. These qualities makes them an ideal companion in the great outdoors.

Kowa's Utilizes a new innovative inner focus system to decrease image movement when focusing on objects-even single handed.

Kowa offers a total solution for Digiscoping that allows enthusiasts to combine the high optical performance of Kowa’s scopes with the quality of various digital, SLR and video cameras in a revolutionary way. Their complete system of adapters offers users the opportunity to observe, photograph and film nature with integrated functionality that was previously unimaginable.
