Kowa TSN-500 Spotting Scopes
The Kowa TSN-500 spotting scope series is comprised of two models (TSN-501 angled, and TSN-502 straight) made of lightweight polycarbonate tubes and standard glass. The bodies are waterproof and nitrogen purged with non-interchangeable 20-40x zoom eyepieces. Dual focus knobs make it easy to focus finely, or speed from infinity to the 8.2' close focus.
