Fortuna General 50M3 Thermal Imaging Monocular

• 50 mm F/1.2 objective: the large fast lens gathers more thermal energy, helping the monocular show stronger contrast and clearer target outlines at longer distances and in poor weather.
• 384x288 microbolometer sensor: this sensor format gives the Fortuna General 50M3 a practical balance of detail, refresh speed, and manageable size for handheld thermal observation.
• 50 Hz refresh rate: fast image updates make panning smoother and help keep moving animals or vehicles easier to follow without a jerky view.
• 800x600 AMOLED display: the high-contrast display presents the thermal image with good apparent sharpness and comfortable viewing in darkness.
• Compact waterproof housing: the rubberized body, nitrogen filling, and weather-resistant construction support reliable field use in rain, cold, and changing temperatures.

About the Fortuna General Series

Fortuna General is a family of compact thermal devices built for short- and medium-range use. Within the range, Fortuna offers 25 mm, 40 mm, and 50 mm lens variants, giving users a choice between wider viewing and stronger reach depending on the task. The series combines a rubberized aluminum housing with waterproof construction, so the devices remain practical for field carry and regular outdoor use.

A defining trait of the General line is its flexible design. Fortuna positions these models as thermal devices that can serve for handheld observation and, in some configurations, as weapon-mounted sights. Across the series, the manufacturer lists 384 × 288 or 640 × 480 sensors with 17 μm pixel pitch, together with automatic silent calibration and an 800 × 600 AMOLED display. That combination is aimed at users who want a clear thermal image, straightforward operation, and a housing compact enough for mobile hunting or general night observation. The General family is also described as resistant to recoil from large-caliber firearms, reflecting a design approach focused on durability as well as portability.

About the Fortuna General 50M3 Thermal Imaging Monocular

Fortuna General 50M3 Thermal Imaging Monocular is the longer-reaching handheld model in this configuration, pairing a 4.20 x base magnification with a 50.00 mm objective. That setup suits users who need more target detail at distance than a wide-angle thermal monocular can provide. With a stated detection range of 1800.00 m, it is built for scanning open ground, checking tree lines, and identifying heat sources well beyond normal visual range.

Its 384x288 microbolometer sensor, 17.00 μm pixel pitch, and 50.00 mK sensitivity work together to produce a usable thermal image with enough separation between background and target for real field observation. The 50.00 Hz refresh rate helps when tracking movement, while the silent calibration mode avoids the distraction of audible shutter noise during observation. The 800x600 AMOLED display gives the image a crisp, high-contrast presentation, and the 7.40 ° field of view keeps enough scene coverage for scanning without giving up the reach expected from a 50 mm thermal lens.

In use, the monocular is shaped for practical outdoor handling. The 25.00 mm eye relief and -5 / +5 diopter range help adapt the view to different users, while the 710.00 g body remains portable for extended handheld observation. A CR123A power supply with 5.00 h battery life supports mobile use, and the waterproof, fogproof, nitrogen-filled construction is suited to cold mornings, damp ground, and changing weather. WiFi connectivity and video output add useful options for external viewing, even though the unit does not record internally.

About Fortuna

FORTUNA is a Russian manufacturer focused on thermal imaging devices for hunting, night shooting, and sport shooting. The company develops both thermal hardware and the software used in its products, which gives it a concentrated specialization in this segment rather than a broad general optics catalog. The FORTUNA trademark was registered in 2010, and the brand's thermal imagers are produced at LLC Modul in Moscow, Russia.

The product range includes thermal sights, monoculars, binoculars, and clip-on attachments, showing a clear emphasis on observation and aiming devices built around thermal technology. Within that lineup, the General family covers compact models for short- and medium-range work, while the broader catalog reflects Fortuna's experience in building field-ready thermal systems for sporting and hunting use.
