Fortuna General 25M3 Thermal Imaging Monocular

• 384x288 thermal sensor: The microbolometer sensor with 17.00 μm pixel pitch gives this monocular enough detail for reliable short- to medium-range observation while keeping the device compact and easy to carry.
• 800x600 AMOLED display: The AMOLED screen presents a clear, high-contrast image that remains comfortable to view for extended periods and helps with target recognition in darkness, fog, and mixed backgrounds.
• Silent calibration: Fortuna’s electronic silent calibration maintains image consistency without the distracting click of a shutter, which is useful when observing game or scanning quietly at night.
• Compact 25 mm F1 objective: The 25.00 mm lens and wide 14.60 ° field of view make the device well suited to scanning larger areas quickly and detecting heat sources at closer and medium distances.
• Field-ready housing: The rubberized body, IPX-6 waterproofing, fogproof construction, and operation from -30 / + 50 °C support dependable use in harsh weather and demanding outdoor conditions.

About the Fortuna General Series

Fortuna General is a family of compact thermal devices intended for short- and medium-range use, covering both handheld observation and weapon-oriented configurations within the same broader platform. In Fortuna’s lineup, the series sits as a practical, field-focused option for users who need thermal capability in a manageable format rather than a large specialist system. Across the range, General models are built around either 384x288 or 640x480 sensors with 17 μm pixel pitch, giving buyers a choice between lighter, simpler setups and higher-detail variants.

A defining feature of the series is its combination of silent electronic calibration and an 800x600 AMOLED display, which supports stable image presentation and comfortable viewing in low-light and no-light conditions. Fortuna also positions the General family around a durable mechanical design, with a rubberized aluminum housing and waterproof construction for regular outdoor use. Lens options in the series include 25 mm, 40 mm, and 50 mm variants, allowing the platform to be adapted to wider-field scanning or longer-distance observation depending on the model.

About the Fortuna General 25M3 Thermal Imaging Monocular

The Fortuna General 25M3 Thermal Imaging Monocular is the compact wide-field member of the General family, built for handheld thermal observation where fast area coverage matters more than high base magnification. Its 2.00 x starting magnification, digital increase up to 8.50 x, and 14.60 ° field of view make it well suited to scanning woodland edges, open fields, tracks, and other environments where a broader image helps locate movement quickly. The 25.00 mm F1 objective supports good thermal intake for a device of this size, while the stated 685.00 m detection range gives it useful reach for spotting heat signatures before moving closer for identification.

The imaging core uses a 384x288 microbolometer with 17.00 μm pixel pitch, 60.00 mK NETD, and a 50.00 Hz refresh rate. In practice, that means a fluid image when panning and enough thermal separation to distinguish animals, people, and vehicles in difficult visibility. The 800x600 AMOLED display helps preserve contrast and viewing comfort, while the -5/+5 diopter adjustment allows the image to be tailored to the user’s eyesight. Because this model does not rely on photo or video recording functions, the design stays focused on direct observation. A 480.00 g weight, compact 165.00 mm body, CR123A power supply, and 5.00 h battery life make it practical for mobile use, and the fogproof, waterproof, rubberized housing is designed for regular field carry in poor weather.
