By pulsing the light from your Telrad Reflex Sight, it makes it easier to find faint stars. The Telrad Pulser is user-installed modification for your Telrad Reflex Sight. It converts the variable brightness red reticle to a variable brightness with variable pulse rate reticle. Once installed, the Pulser control allows you to vary the rate that the reticle blinks on and off. The existing Telrad brightness control still works as before, and now that the unit pulses on and off, the very long battery life of the Telrad is further improved.
Installation requires the use of a drill and some rewiring. No soldering is required.
