Product Overview

Kowa Prominar 77mm w/25-60x

The TSN-773 approaches the compactness of a 66mm scope but the optical performance of an 80mm scope using Kowa's XD lenses (eXtra-low dispersion glass) reduces a high percentage of chromatic aberration for an excellent viewing experience. The magnesium alloy body is waterproof and dry nitrogen filled to prevent internal fogging. Kowa’s dual focus system is both smooth and fast, shifting from infinity to 16 feet in two turns of the knob. Paired with Kowa’s TE-11WZ it offers a wide-angle 25-60x zoom range. Though not the equal of the TSN-883 at the highest magnification, this is a fine scope worthy of your consideration.
