The Kowa TSN-663M (angled) 66mm Prominar XD Spotting Scope features high-quality optics built into a body that is designed for reliable use under a variety of viewing conditions. Measuring 30.1 cm long and constructed from magnesium alloy, this durable scope can provide a wide-angle or a versatile viewing range.
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 Spotting Scope's Prominar XD (extra-low dispersion) lens and a concave dispersion lens work together to minimise chromatic aberrations. Additionally, multicoated optical surfaces help to consistently maximise light transmission, sharpness, and colour fidelity.
A nitrogen fill prevents fog accumulation and an O-ring sealed waterproof construction further adds to the rugged design of the 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.
