Independent, non-aligned origin, with no political exposure to any major-power ecosystem.
One accountable team from first briefing through delivery and in-region sustainment.
Shutterless, TEC-less core: no image freeze for calibration during an engagement.

Questions buyers ask
What is a thermal weapon sight?
It is a rifle-mounted sight that forms its image from heat rather than light, so a shooter sees a target in total darkness, smoke or haze. Ours uses an uncooled 640x480 vanadium-oxide detector behind a 54 mm F/1.0 objective, giving human recognition at 1,000 m and identification at 500 m, on a shutterless, TEC-less core that outputs a continuous image and never freezes to calibrate mid-engagement.

How far can a thermal weapon sight recognise a person?
This sight gives human recognition at 1,000 m and identification at 500 m. Note that competitors often quote a detection range, which is the longest and easiest of the detect-recognise-identify trio, so a rival's 1,800 m or 2,600 m detection figure is not the same claim as a 1,000 m recognition figure. Ask each vendor for detection, recognition and identification against the same target before you compare.
What does a shutterless thermal sight change?
It stops the image freezing. Most uncooled thermal cores use a mechanical shutter for flat-field correction, which blanks the picture for a fraction of a second while it recalibrates. On a weapon sight that can be a blank frame during an engagement. Our core is shutterless and TEC-less, so it outputs a continuous image with real-time noise reduction and never blanks to calibrate. That is a design choice worth confirming with any vendor.
Thermal weapon sight that runs on standard batteries in the field
It runs six hours or more on two commodity 18650 lithium cells, which a soldier can carry spares of and swap in the dark. Some rivals quote longer runtimes, but on internal or proprietary packs you cannot always source in the field. A standard cell you can replace anywhere often beats an extra hour on a pack you cannot resupply, so weigh runtime against how easily the battery is replaced.
Rugged thermal sight for hard use, -40 degrees and heavy recoil
It is rated to 800 G shock and an operating range of -40 to +55 degrees C, and weighs no more than 880 g on the rail. That shock rating and cold limit sit at the demanding end of the class; some rivals state a warmer lower limit or do not publish a shock figure. If your use includes hard recoil and extreme cold, hold each vendor to a stated shock G figure and temperature range rather than a general ruggedness claim.
Thermal sight with onboard recording and video transmission
It transmits imagery over Wi-Fi and records photo and video to 32 GB of internal memory, and it carries an electronic compass and pitch display for bearing and elevation. That lets a shooter capture an engagement and share the view without a separate device. Confirm the transmission range and the app or receiver you would use, because Wi-Fi range in the field depends on the environment.
How do we compare thermal sensitivity between sights?
Check what the number measures. Our sensitivity is stated as an MRTD of 550 mK, a minimum resolvable temperature difference measured through the whole optical chain. Rivals often quote a bare-sensor NETD in the sub-25 mK band, which is a finer but different test. Because MRTD and NETD are not the same measurement, the fair comparison is the live image on your own targets, not the datasheet unit.
Thermal sight with picture-in-picture and multiple palettes
It offers picture-in-picture and 1x, 2x and 4x digital zoom, with multiple palettes including white hot, black hot and red hot. Picture-in-picture keeps a wide view while a zoomed insert holds detail, and different palettes suit different backgrounds and targets. If a particular palette or the picture-in-picture layout matters to your shooters, confirm the exact options on the current build, because palette sets vary between sights.
A rival publishes finer sensitivity and longer range. Why would we still choose yours?
Read what those numbers measure first. Rivals publish a bare-sensor NETD in the sub-25 mK band and detection ranges from 1,800 m to 2,600 m. Our 550 mK is an MRTD through the whole optical chain, a coarser and different test, and we quote recognition at 1,000 m and identification at 500 m, which are shorter and harder than detection. So the paper gap is smaller than it looks. The reason to choose ours is the shutterless, TEC-less core that never freezes the image, the commodity 18650 power, the 800 G shock rating, and a non-aligned supply chain, all of which favour hard field and military use.
For a military sight, does it matter where the thermal core comes from?
It matters a great deal. One popular rival has corporate roots that run to Belarus, which carries sanctions exposure; another requires an export-policy acknowledgement at purchase; a third is a US-distributed sight built on a China-origin thermal core, which carries its own supply and export exposure. Our sight comes from an independent, non-aligned supplier, so the sight and its spares stay inside your jurisdiction rather than on a foreign export or sanctions calendar. The imaging physics is similar across the field; the supply relationship is what differs.
We cannot afford the image to blank during an engagement. Can you confirm this core does not?
Yes. The core is shutterless and TEC-less, so it does not use a mechanical shutter for flat-field correction and does not blank the image to recalibrate. It outputs a continuous picture with real-time noise reduction. Most uncooled cores do use a shutter, and none of the competitor pages we checked states a shutterless design, so this is the point to press with every vendor. For a sight used in an engagement, a freeze-free image is a design property, not a menu setting.
We run several weapon types. Can the sight zero and hold across calibres?
It supports manual gun calibration with multiple reticle patterns, plus an electronic compass and pitch display, so it can be zeroed for different weapons and reticles. The catalogue does not publish a per-calibre zeroing profile count, so if you run several weapon types, bring the list to the review and confirm the reticle and zeroing options against them. The recognition at 1,000 m and identification at 500 m are the delivered ranges to plan the zero around.

How should we run a fair trial between this sight and the commercial rivals?
Trial on your own targets, at night, in the conditions you fight in. Because sensitivity is stated as MRTD by us and NETD by rivals, and because rivals quote detection while we quote recognition and identification, the datasheets do not compare cleanly. So put each sight on the same rifle, at the same targets, and judge the live image, the time to recognise and identify, whether the image ever freezes, and how easily the battery swaps. Those field observations settle what the mixed units cannot.
What is the pixel pitch, and what should we confirm before buying?
The catalogue states the detector as an uncooled 640x480 VOx core with an MRTD of 550 mK, but it does not confirm a pixel pitch, so treat the pitch as unconfirmed and ask for it at the review. Confirm the pitch, the exact display resolution and the transmission range for the current build, alongside the shutterless core and the 18650 runtime. The recognition and identification ranges, the 54 mm F/1.0 objective, the 800 G shock rating and the sub-880 g weight are the delivered specification.
Is this a fielded weapon sight or a prototype?
Fielded. It is a 640x480 uncooled thermal weapon sight in service, rated to 800 G shock and -40 to +55 degrees C, weighing no more than 880 g, with human recognition at 1,000 m, the shutterless TEC-less core, Wi-Fi transmission and 32 GB recording quoted here as the delivered specification. The ranges are recognition and identification figures, not the longer detection figures rivals often quote.
