THE PHILOSOPHY
Hunting is a 24-hour discipline.
640 × 512 · LWIR · ≤25MK NETD
IP67 · 1000G SHOCK RATED
Darkness is not an obstacle. It is an advantage — for the hunter who is prepared. The moments before first light, the fog-shrouded valley at dusk, the driving rain that sends amateurs home: these are precisely the conditions when experienced hunters press their edge. That edge, today, is thermal.
"The animal moves when it feels safe. It feels safe in the dark. Your task is to remove that safety — silently, precisely, invisibly."
IREO's hunting series is built around one conviction: no single device serves all scenarios. A clip-on thermal that converts your day scope into a night instrument serves the precision shooter at fixed range. A monocular rangefinder serves the stalker scanning open ground. A head-mounted fusion system serves the driven hunt where hands must remain free and targets emerge at speed. Each is engineered for its role. Together, they cover the complete hunting environment — from pre-dawn glassing to the recovery trail at midnight.
Across the .. range, every unit shares the same detector family: a 640×512 uncooled LWIR sensor operating at 12µm pixel pitch with NETD below 25mK at sensor level — the honest measurement, not the post-processing figure competitors quote. What changes is the optic, the form factor, and the mission.

WEAPON-MOUNTED · CLIP-ON
The Precision
Strike.
| .. STRIKE |
It is 04:30. The boar population has been moving through the valley edge for six consecutive nights. You have been at your position since 03:45 — scope zeroed at 150 metres, the same zero that took you four sessions to perfect on your trusted day optic.
This is the fundamental problem with dedicated thermal riflescopes: they replace your zero, your magnification system, your point of impact reference. The .. Strike was designed around the opposite principle. It clips onto the front of your existing optic — in ten seconds, without tools — and converts it directly into a thermal instrument. Your reticle remains. Your zero remains. Your night begins.
Compatible with the Picatinny rail system and clamping solutions common across European sporting rifles, the Strike preserves exit pupil distance precisely. The 640×512 sensor delivers the thermal image through your existing eyepiece as if the world were mid-afternoon — hot signatures against a cooled landscape, details resolved to the limits of the detector.
Choose your engagement profile. Choose your lens. The 25mm variant opens the widest field for driven hunts and boar approaches in cover. The 35mm extends effective recognition range for red deer on woodland edges. The 50mm is the long-range tool — open ground, chamois country, the shot across the valley floor at first and last light.

HANDHELD OBSERVATION · LRF
Glass the Ground.
Track. Decide.
| .. TRACKER |
The stalk begins not at the shot, but two hours earlier — on the hillside with glass in hand. Identifying species, counting points, judging the stag that has been moving this corridor for three seasons. In thermal, this process is transformed.
The .. Tracker is a monocular thermal rangefinder designed for exactly this work. It does not go on the rifle. It goes in your hand — or your jacket pocket — and it tells you what is on the hillside, how far away it is, and whether it is worth the approach. The integrated laser rangefinder measures to 2,200 metres with ±1 metre accuracy, in single shot or continuous mode, while the thermal image renders warm bodies against a cold landscape with complete clarity regardless of ambient light.
The 35mm lens offers the ideal balance for open-country glassing: sufficient magnification to identify and assess at practical hunting ranges, wide enough to locate and track moving animals across the frame. For close-country work — dense woodland, driven boar — the 25mm widens the field and accelerates acquisition. Both share the identical sensor, identical build quality, identical 6-hour battery life.
At 400–450 grams, the Tracker is the tool that stays in your pack for the entire day. Built-in WiFi streams live imagery to your phone for team coordination. The data card holds everything you observe. Nothing about the approach is left to memory.

HEAD-MOUNTED · HANDS-FREE
Move Through
The Veil.
| .. VEIL · WHISPER |
The driven hunt moves fast. Dogs push through the undergrowth. Shooters on the line must track movement, identify species, confirm direction — in fractions of a second, often in conditions where a handheld monocular is simply not fast enough. The hands must be free for the rifle. The eyes must be in the thermal.
The .. Veil and .. Whisper solve this with two complementary head-mounted configurations. Both mount to standard helmet rails and J-arm accessories common in the European hunting community. Both leave both hands completely free. Both can be flipped away from the eye in an instant when transitioning to the optic.
THERMAL
Penetrates fog, rain, smoke, dust. No ambient light required. Animal heat signatures visible at maximum range.
LOW-LIGHT
Amplifies ambient starlight and moonlight to reveal texture, colour context, and fine spatial detail.
FUSION
Dual-band overlay combines thermal detection with visible-light detail. Recognition distance extended significantly.
The .. Veil carries IREO's dual-band fusion capability in a 270-gram head-mounted form. The thermal channel detects animal heat. The low-light channel adds visible texture and spatial context — the shape of the antlers, the colour of the coat, the precise angle of approach. Both channels overlay in real time. You see more than thermal alone can show you.
Where the Veil prioritises sensor capability, the .. Whisper prioritises weight. At approximately 96 grams, it is the lightest head-mounted thermal in the range — designed for alpine hunting where every gram is carried in vertical elevation, and for the long drives where fatigue is an opponent. Single-channel thermal. Maximum detection geometry. No excess.

ALL-CONDITIONS · MULTI-SPECTRUM
When the Weather
Closes In.
| FULL SYSTEM |
Rain at nightfall. Fog on the valley. The hunting season does not pause for poor visibility — and neither does the quarry. Where optical magnification and image intensification fail, thermal imaging continues to perform. The 8–14µm LWIR band passes through atmospheric water vapour with far greater fidelity than any visible-spectrum optic. The animals remain visible. The landscape remains navigable. The hunt continues.
"In twenty years of night hunting, I have never once wished I had less thermal capability. I have frequently wished for more."
The complete .. hunting system is designed as an integrated toolkit rather than a collection of individual devices. The Strike clip-on converts your precision rifle instrument. The Tracker informs your approach before the shot. The Veil or Whisper keeps your hands free for whatever the night demands. Each is purpose-matched to its moment in the hunt. Together, they eliminate the gaps in your capability that darkness used to represent.
All .. products share identical environmental standards: IP67 waterproofing verified against sustained immersion, operational temperature tolerance from −20°C to +55°C, and 1,000G shock resistance for mounting on centrefire rifles. They are instruments that work in the conditions that matter most.
