enhances the performance of your device, while remaining almost totally invisible to the
naked eye. In dark environment, power up the scope. Now, find a scene and examine it
without the IR on then with IR powered up. Note the difference in illumination. It is impor-
tant to remember that the IR illuminator is simply an infra red light source, and like any light
source it may loose its effectiveness over a great distance.
For installation of the IR illuminator onto the bi-ocular use the picatinny rail.
