The MICRO 2 H25 is the next generation in the RH25 thermal optic line, keeping the same 4-in-1 versatility as a helmet-mounted, clip-on, handheld, and standalone weapon sight while upgrading nearly every system underneath. It features a second-generation 640 × 512 detector with 15 mK NETD and a 20% responsivity gain, producing a cleaner, more detailed thermal image than the RH25 V2's 640 × 480 sensor. Its in-house FastEngine architecture cuts latency by 21%, reducing lag and fatigue during long nights of movement. In clip-on mode, it now supports day scopes from 1 to 10× (up from 6×), thanks to a 2560 × 2560, 1.03-inch display. The body is also shorter and narrower, freeing up rail space and improving binocular alignment. Runtime extends to up to 9 hours on a single 18650 battery when using Auto Power Save, and three independent zero profiles let you swap rifles or day optics without re-zeroing. Standalone use adds Picture-in-Picture for a magnified aiming window without losing situational awareness. Across all modes, you get an overhauled UI, -40°F cold-weather batteries, and IP67 water and dust resistance.
