As a birder, hunter, or nature observer, you know that it takes time to find that rare, crystal-clear image of your subject. Getting that perfect shot as if you were right next to it takes plenty of patience, a bit of luck, and absolutely the right optical.
When binoculars simply won’t do for that long-distance view, you’ll be amazed at what a spotting scope can offer you.
Spotting scopes have incredible magnification built within a light construction. Much smaller and more portable than a telescope, spotting scopes ensures that your target is never out of reach.
Whether you use it to identify every tiny detail of a prized buck at long range, observe osprey in the winter, or chase a waterfall, a spotting scope is sure to deliver.
Over the years, spotting scope technology has vastly improved. Top binocular manufacturers consistently offer the best optical instruments on the market and generally sell their own line of spotting scopes.
The most famous brands that offer the best products on the market are Swarovski, Leica, Zeiss, Nikon, Kite, Vortex, Vanguard, and Kowa. Let’s take an in-depth look at the latter…
Established in 1894, Kowa has produced state-of-the-art optical equipment. It has grown into the fifth-largest trading company in Japan and has an active presence throughout Asia, Europe, and the Americas.
This multinational Japanese company participates in manufacturing and trading activities in such fields as optical, pharmaceutical, textiles, and various consumer products.
In 1952, the electronics and optics division of Kowa commenced the production of their line of high-quality spotting instruments. Originally designed for use in shooting events, they were the official spotting scope used at the Tokyo Olympic Games in 1962.
Soon after the scopes were discovered by birders and nature lovers and to this day, are one of the most popular optical instrument brands in the world.
Kowa Spotting Scope Series
Kowa offers a wide range of available scopes and six main sizes with 88mm, 82mm, 77mm, 66mm, 60mm, and 50mm objective lens diameters. In its entirety, Kowa offers 20 spotting scope models, but most are sold as body only.
For convenience, each size forms part of a series and you can choose either angled or straight body designs.
