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.

Performance notes
Fixed 40x magnification through a 55mm objective is a common mid-size spotting scope spec, giving a consistent view without a zoom ring to adjust in the field.
