The Gen 1 image tube works well with moonlight and starlight, but Yukon's exclusive built-in PULSE Infrared (IR) Illuminator with a range of 100 m extends the NVRS' viewing range. The PULSE system utilizes quick infrared energy bursts that pierce the darkness further to increase distance, visibility and image quality. The PULSE IR System provides the highest level of infrared illumination without significant battery drainage. The same “pulsing” frequency that is invisible to human eyes infiltrates longer distances due to the Infrared Illuminator's quick energy bursts.
