Product Overview

Kowa Prominar 55mm w/15-45x

Kowa's flagship TSN-883 has been respected among top shelf spotting scopes for years. Now Kowa brings the same level of optical quality to the compact travel scope market. The TSN-553 is, quite simply, the finest spotting scope under 60 mm on the market today. It’s the only scope other than the TSN-883 to utilize Kowa's PROMINAR Fluorite Crystal objective lens to minimize chromatic aberration. A 15 to 45x eyepiece matched with dual fast and fine focus knobs provides both speed and accuracy. The poly-carbonate housing is fog proof and waterproof, yet the whole kit weighs only 28.5 ounces – about the same as many 8x42 binoculars!
