The green, straight-viewing TSN-664M 66mm PROMINAR XD 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 12.3" 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-664M 66mm Spotting Scope's PROMINAR XD (extra-low dispersion) lens and a concave dispersion lens work together to minimize chromatic aberrations. Additionally, multi-coated 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 adds to the rugged design of the TSN-664M 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.
