Description
The Holosun DRS-TH (Digital Reflex Sight — Thermal) combines a high-performance LED red dot with an integrated 256×192 thermal sensor, overlaying real-time heat signatures directly within a familiar red dot sight picture. The result is dramatically faster target detection and engagement in total darkness, smoke, fog, or daylight — a genuine all-conditions fusion optic for professional and field use.
White Hot, Black Hot, Outline, and Highlight thermal modes adapt to changing environments, while selectable 1x–5x digital zoom and onboard video recording add field flexibility. The Multi-Reticle System offers a 2 MOA dot, 65 MOA circle, or circle-dot, and if thermal isn't needed, simply flip down the front lens cap and run the DRS-TH as a standard red dot. Two rechargeable 18350 batteries with magnetic USB charging power the system inside an IP67-rated 7075-T6 aluminum housing.
