Pixfra Mile 2 M425
Thermal Monocular 384×288 · 25 mm · 1,300 m
High-resolution thermal monocular with 384×288 sensor, 12 μm pixel pitch, NETD ≤25 mK and 1,300 m detection range – Forest mode, hot spot tracking, IP67, 8 h runtime.
384×288 thermal monocular with 1,300 m detection range
The Pixfra Mile 2 M425 is the highest-specification model in the Mile 2 compact series: a 384×288 VOx thermal sensor (12 μm pixel pitch, NETD ≤25 mK) paired with a 25 mm F1.0 lens delivers a detection range of up to 1,300 m – nearly twice that of the smaller M215M. The 1×–8× digital zoom yields a total magnification range of 2.70× to 21.6×. Weighing under 320 g, the M425 fits in any jacket pocket.

384×288 sensor with NETD ≤25 mK – more pixels, better sensitivity, twice the range
The 384×288 VOx thermal sensor with 12 μm pixel pitch and a spectral range of 8–14 μm achieves a thermal sensitivity of ≤25 mK thanks to the fast 25 mm F1.0 lens. This means the M425 resolves temperature differences that lower-resolution sensors would miss entirely. A field of view of 10.9°×8.2° (19.2 m×14.4 m at 100 m) and a detection range of 1,300 m make it the ideal choice for demanding hunting, wildlife observation and tactical use.
Forest mode, hot spot tracking and digital compass
Beyond standard thermal imaging, the M425 offers two particularly practical modes: Forest mode strongly highlights high-temperature targets (e.g. heat-emitting animals) against a vegetation-rich background, making target identification in dense cover significantly easier. Hot spot tracking marks the warmest point in the image in real time – ideal for rapidly spotting game in grass or undergrowth. An integrated digital compass provides orientation in the field, and the burning protection feature automatically activates the shutter if the lens is exposed to excessive heat radiation.
IP67, 8 h runtime and 3-year warranty
The Pixfra Mile 2 M425 is IP67 certified: completely dust-tight and submersible in up to 1 m of water for 30 minutes. The operating temperature range of −30 °C to +55 °C covers all conceivable outdoor conditions. The built-in Li-Ion battery (3,200 mAh) delivers at least 8 hours of operation at 25 °C; charging is via USB-C (5 V/2 A). Pixfra provides a 3-year manufacturer’s warranty.

Frequently asked questions – Pixfra Mile 2 M425
How does the M425 differ from the smaller M215M?
Both models belong to the same Mile 2 series but differ in two key areas: first, the M425 offers a significantly higher sensor resolution of 384×288 pixels compared to 256×192 on the M215M. Second, the M425 uses a longer 25 mm lens (vs. 15 mm on the M215M), which nearly doubles the detection range to 1,300 m. Thermal sensitivity is also improved, with NETD ≤25 mK vs. NETD ≤35 mK on the M215M. Housing, battery (3,200 mAh), storage (16 GB) and display (OLED 800×600) are identical between both models.
What is Forest mode?
Forest mode is a dedicated image processing mode that strongly highlights heat sources (e.g. animals) against a vegetation-rich, thermally homogeneous background. High-temperature targets are emphasised while the surrounding environment is rendered cooler. This makes target identification and tracking significantly easier in dense cover or woodland, where standard palettes produce little contrast between an animal and its surroundings.
What does hot spot tracking do?
Hot spot tracking automatically marks the highest-temperature point in the current image with a real-time indicator – no manual searching required. This is particularly useful for quickly reacquiring fleeing game within the field of view, or for monitoring heat distribution in a building, vehicle or piece of machinery.
Can I record video with the M425?
Yes. The Pixfra Mile 2 M425 records video in H.264 format and still images directly to its 16 GB internal storage. Files can be transferred to a computer via USB-C (mass storage mode) or shared wirelessly via the Pixfra Outdoor app (iOS & Android) over Wi-Fi.
How do I connect the M425 to my smartphone?
Press the Wi-Fi button to activate the built-in hotspot (2.4 GHz). The hotspot supports up to 4 devices simultaneously within a 40 m radius. Launch the free “Pixfra Outdoor” app (iOS & Android) and connect to the device’s network. The app provides live streaming, remote shutter, file transfer and device settings.
How long does the battery last and can it be replaced?
The built-in Li-Ion battery (3,200 mAh) provides approximately 8 hours of operation at 25 °C. The battery is integrated and not user-replaceable; it is charged via the USB-C port (5 V/2 A). For extended field use, an external USB-C power bank is recommended for recharging on the go.
How waterproof is the Pixfra Mile 2 M425?
The Mile 2 M425 is IP67 certified: completely dust-tight and submersible in up to 1 m of water for 30 minutes without damage. It is therefore well suited for rain, snow and wet outdoor conditions. Operating temperature ranges from −30 °C to +55 °C.
What does a NETD of ≤25 mK mean?
NETD (Noise Equivalent Temperature Difference) is the measure of a thermal sensor’s sensitivity: the lower the value, the smaller the temperature differences the device can resolve. A NETD of ≤25 mK means the M425 can detect temperature differences as small as 0.025 °C – representing very high sensitivity. For comparison, a sensor with NETD ≤35 mK (like the M215M) only resolves larger differences.
