Overview Specs In the Box Reviews Accessories Q&A The gray, angled viewing TSN-663 66mm Spotting Scope from Kowa features high-quality optics built into a body that is designed for reliable use under a variety of viewing conditions. Measuring 12.2" long and constructed from magnesium alloy, this durable scope can provide a wide angle or a versatile viewing range depending on which separately available eyepiece is installed on it. Compatible Kowa eyepieces include the TE-14WD 30x Wide Angle Eyepiece, the TE-17HD 25x Long Eye Relief Eyepiece, and the TE-9Z 20-60x Zoom Eyepiece. While in use, the TSN-663 66mm Spotting Scope's PROMINAR XD (eXtra-low dispersion) Lens and a concave dispersion lens work together to minimize chromatic aberrations. Additionally, multicoated optical surfaces help to consistently maximize light transmission, sharpness, and color fidelity. A nitrogen fill prevents fog accumulation and an O-ring sealed waterproof construction further add to the rugged design of the TSN-663 66mm Spotting Scope. Conforming to JIS (Japanese Industrial Standard) Protection Class 7 waterproofing, this scope can withstand momentary immersion, assuming the eyepiece mount is not open and exposed.
