Overview

Fixed at 40x magnification through a 55mm objective lens, the Kowa TSN-55A spotting scope is built in polycarbonate with a green finish.

A 55mm objective at fixed 40x magnification puts this scope in mid-size spotting scope territory, aimed at buyers who want a set zoom rather than a variable range to dial in. The listing's dimensions and weight figures look inconsistent with a handheld spotting scope, likely reflecting packaging rather than the scope itself, so don't rely on them for carry weight.

Who it's for

Fits buyers who want a fixed 40x view rather than a zoom range, and who prioritize a polycarbonate build. Buyers wanting exact size and carry weight should confirm those figures with Kowa directly.
