Questions? Ask our experts:

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.

    Comments about Kowa TSN-663 66mm Spotting Scope (Angled Viewing, Gray):

    I needed a lightweight, compact scope for birding to take along on my bike or for hiking. Optically, this scope has excellent resolution. Coupled with a 30x fixed eyepiece you get a generously wide FOV. At this price point you can't do better.

    Long Range Spotting Excellence

        Best Uses

          Comments about Kowa TSN-663 66mm Spotting Scope (Angled Viewing, Gray):

          I bought this spotting scope to use for scoring in long range shooting. This requires a spotting scope to be able to clearly resolve bullet hole makers placed on a target face at ranges out to 1000 yards.The spotting scope needed to be light and portable and the 66 mm Kowa TSN-663 was around the right dimension and weight. I decided the Flourite glass was needed for the best light transmission and image resolution.So much for the theory of selecting the Kowa scope, how did it shape up under use in the field? I am pleased to say the image quality thru both the 20-60 zoom and the 30X wide eyepieces that I purchased with it is simply outstanding! On cooler days, (I live in Australia) that are mirage free the image is like standing directly in front of the target as the scope compresses the distance so well.I also take the scope slightly out of focus to view the mirage on hot days to get an indication of the winds activity. This spotting scope does everything I want and provides a very bright and well resolved image. Its that good I have just ordered a camera adapter for it to use with my Canon G12.One drawback with this scope is that you must purchase a protective cover/carry case for it. I think for the price maybe Kowa should have included one in the box with it.The purchase of this spotting scope has been a very positive experience [...].The outcome of my experience is that I would definitely recommend the Kowa TSN-663 to anyone looking to use it for long range target shooting.
