The Holsoun DRS-TH (Digital Reflex Sight - Thermal) redefines the boundaries of red dot optic technology. Using a 256x192 thermal sensor, the DRS-TH fuses together your traditional red dot optic with a thermal overlay to give you the best of both worlds. Up to 10 hours of battery runtime for the thermal sensor and over 50,000 hours of runtime for your red dot gives users an optic that can keep up with the most demanding tasks. White hot, black hot, outline, and highlight modes give you flexibility depending on the settings. Capture the action through the thermal with the built in internal video recording that is as easy as a single button press. If thermal isn't needed for the task, simply flip down the front lens cap and use the DRS-TH just as you would any of Holosun's traditional red dot optics, giving you the best of both worlds.
