Engineered for high definition, “white hot” and “black hot” target viewing at distances of more than 1,000 yards away, the HD38S is the premier choice for a wide variety of applications including: search and rescue missions, reconnaissance, hunting, and covert law enforcement/military operations. The HD38S features 3 new operating modes and calibration modes, allowing users to customize the monocular to their surrounding environment.

The Quantum HD38S can detect heat signatures beyond what night vision can see, successfully penetrating through fog and smoke in day and nighttime operations. The 3 new brightness modes (City, Forest and Identification) deliver enhanced contrast, significantly improving rendering of hot object details. Operators can choose from the automatic, manual or semi-automatic calibration modes, which calibrates the image in just 1 to 2 seconds.
