Kowa TSN 66A Prominar Angled Body Spotting Scope and 25-60x Wide Zoom Eyepiece

Crafted in Japan with the highest standards, the TSN-66A brings the signature PROMINAR precision to a more portable and streamlined body, making it the ideal choice for birdwatchers, naturalists, and wildlife photographers seeking professional-grade optics in the field. The use of pure fluorite crystal—a material known for its exceptional light transmission and minimal chromatic aberration—ensures that every detail is captured with absolute sharpness and vibrant, true-to-life colour.

Engineered for durability and field performance, the scope features a magnesium alloy body that is both robust and lightweight. Fully sealed and 100% waterproof with nitrogen filling, it offers reliable performance in any weather. With a minimum focusing distance of just 3.5 metres, the TSN-66A allows users to observe both distant landscapes and close-up details with stunning clarity.

The dual focus system provides effortless and precise control, combining a fast focus mechanism to bring subjects into view quickly, with an ultra-fine focus wheel for detailed refinement. Whether you’re tracking a fast-moving bird or studying intricate feather patterns, the TSN-66A ensures your focus is always sharp and accurate.

Included with the scope is the TE-11WZ II 25-60x wide zoom eyepiece, offering a bright, expansive field of view throughout the zoom range. Together, they deliver one of the most versatile and high-performing optical systems on the market, perfect for everything from long-distance observation to detailed digiscoping.

As part of the Kowa System, the TSN-66A is fully compatible with a wide range of accessories and interchangeable eyepieces, giving users the flexibility to adapt the scope to their specific needs. The 72mm filter thread adds even more versatility, allowing for the use of standard photographic filters in the field.

Weighing just 1895g with the eyepiece, and measuring only 365mm in length, the TSN-66A PROMINAR is the ultimate travel companion for serious nature enthusiasts. It arrives complete with an objective lens cap, cleaning cloth, and the confidence of a 10-year warranty, extendable by a further 5 years with online registration.
