It is the smallest 1280 thermal optic on the market and the first 1280 helmet-mounted thermal monocular. Its 1280 × 960 sensor captures 4× the pixels of its predecessor, the RH25 V2’s 640 × 480 sensor. The MICRO 2 more than doubles the RH25 V2’s display, jumping from 1440 × 1080 to a razor-sharp 2560 × 2560 (nearly 4.7× the pixels), delivering a sharper, more detailed image that holds up at higher digital zoom and makes it easier to pick out fine thermal detail.  The 34.2° × 25.9° ultra-wide field of view is roughly double the 17.5° × 13.1° typical of helmet-mounted thermals and comes close to the roughly 40° of a PVS-14, which makes it a strong fit for thermal binocular and dual-band builds. FastEngine low-latency architecture keeps latency over 100% lower than conventional 1280 thermal systems, and a 60 Hz refresh rate keeps the image smooth during movement. In clip-on mode it supports day optics up to 10× (up from 6× on the RH25 V2), with a reworked zeroing process and UI. Dual-Link pairs two units into a single binocular system controlled from one master unit, while NV Highlight and NV Outline modes simplify the thermal image for cleaner fusion with night vision in dual-band setups. Standalone use adds Picture-in-Picture, which keeps the full field of view live while opening a magnified window around the target and reticle. Across all modes, you get a simplified UI, 1080p recording, 64GB of onboard storage, cold-weather batteries rated to -40°F, and IP67 water and dust resistance.

• Resolution: The industry-first 1280 × 960 thermal sensor captures 4× the pixels of the RH25 V2’s 640 × 480 sensor, and the 2560 × 2560 circular AMOLED display delivers the resolution to put that extra data to use.
• Field of view: The 34.2° × 25.9° ultra-wide FOV is roughly double the width and height of the 17.5° × 13.1° typical of helmet-mounted thermals and closes in on the roughly 40° of a PVS-14, covering more terrain per glance with less head movement.
• Enhanced clip-on support: Clip-on mode now supports day optics from 1 to 10× (up from 6×), thanks to the 1.03-inch AMOLED display.
• Clip-on zeroing: Three independent zeroing profiles with numerical zero values let you save distinct zeros across rifles or day-optic setups without re-zeroing.
• Clip-on UI: Zero, battery status, and mode indicators are positioned to stay visible without occluding the sight picture or crowding the target area.
• Dual-Link: Two ULTRAs pair into one thermal binocular system with menu, palette, image settings, and zoom controlled from a single master unit.
• Optimized for dual-band: Dedicated NV modes strip out low-temperature ambient clutter so thermal and night vision fuse more easily, and outline mode reduces heat sources to clean outlines that give location and shape while night vision carries the environmental picture.
• Shutter: A 0.1-second seamless shutter cuts motion artifacts and interruptions.
• Magnification: 1× base magnification with up to 8× digital zoom gives a wide native picture for search, then lets you close in on a heat signature, with smoothed zoom transitions for a more natural feel.
• Wireless remote: The included remote controls recording, brightness, and menus, with a scroll wheel for digital magnification and menu navigation without taking your hands off the gun or tripod.
• Power management: True Sleep drops the unit into an ultra-low-power state during downtime, flip-to-standby powers it down the moment it’s flipped out of position, and Power-Saving Mode stretches runtime to 6 hours on a single 18650 battery.
• Handheld scanning: Covers ground quickly while retaining the detail to confirm what you’ve found, suiting hunting, predator control, property scanning, and wildlife observation.
• Weapon sight controls: Customizable reticles, app-based zeroing, and adjustable reticle brightness provide the controls expected from a modern thermal riflescope.
• Recording output: Recorded video resolution increases from 768×576 on the RH25 V2 to 1280×960 on the H25, roughly 2.8× the pixels, for noticeably sharper footage.
