KOWA TSN-660 Spotting Scopes
We are proud to carry the entire line of Kowa Spotting Scopes

Kowa TSN-660 Spotting Scopes
These high performance models have been created by taking the superior qualities of the TSN-820M Series and putting them into a smaller, more compact scope. These sophisticated scopes satisfy the needs of users in all fields, from beginning bird watchers to scientific researchers.
The 66mm diameter objective lens has more than 120% light gathering power of the 60mm objective lens. All optics are fully multi-coated fro brighter, clearer and sharper viewing. Prominar ED models are also available for even better optical performance with optimum color definition.
Main body length of about 30cm and weight of only 1 kg. Available in Angled or Straight viewing types with the Kowa easy-to-use functions.
An all weather scope completely sealed making it fully water-proof Nitrogen gas purged to prevent the lens from fogging. "Not intended for underwater use".
Kowa has a Lifetime Warranty for all Kowa TSN-660 Spotting Scopes.
