Aiming module safety: never allow the aiming module beam or its mirror reflection to enter the eyes. Handle the red aiming module module responsibly and follow the manual.
In short: the Zenitco Klesch-1 + LTsU (Red) combines a white-light LED illuminator and an integrated red aiming module in one compact D16T aluminum body. The light gives at least 300 lux in constant mode and 500 lux in boost mode at 5 m. It runs on two CR123 cells and ships with interchangeable end caps for long-arm and compact platform setups.
Overview
The Klesch-1+LTsU V1.1 puts a light and a red aiming module in one body, so a single unit and a single mount cover both jobs. It is built for sidearms and carbines alike, with rear caps that adapt it to either.
Output at 5 m is at least 300 lx in constant mode and 500 lx in boost, from two CR123A cells running no less than 1.2 hours. With the sidearm rear part fitted it measures 102 x 38 x 37 mm and weighs 157 g without cells. This version uses Zenitco's own new connector.
Compatibility Note: mounts on a Picatinny (1913) rail. the aiming module beam must never be directed at anyone's eyes, directly or by mirror reflection. For a Yarygin-pattern sidearm frame the B-8 adapter is required, sold separately.
