Pulsar Avilume XT50 Pro Multispectral Wildlife Binoculars

Pulsar Avilume XT50 Pro Multispectral Wildlife Binoculars

Pulsar Avilume XT50 Pro is a premium multispectral binocular system combining a 1280 × 1024 thermal sensor, 4K digital day and night imaging, an 850 nm infrared illuminator and an integrated laser rangefinder. It allows the user to locate a bird or animal by its heat signature, switch to the digital channel for visual identification, measure the distance and record photos or videos with sound.

Designed for birdwatching, wildlife observation, nature photography, conservation work and field research, the XT50 Pro is particularly effective in forests and mixed terrain. Its wide 17.5° thermal field of view covers 30.7 m at 100 m, helping the observer scan large areas quickly and track moving wildlife without constant repositioning.

1280 × 1024 Thermal Imaging

The European uncooled microbolometer has a resolution of 1280 × 1024 pixels, a 12 µm pixel pitch and a 50 Hz refresh rate. This high-resolution thermal channel preserves fine temperature detail, while the 50 Hz image provides smooth observation when panning or following animals in motion.

Sensor sensitivity is rated at NETD <35 mK, with system sensitivity of sNETD <20 mK. These values support useful image separation in rain, fog, high humidity and low-contrast conditions where an animal and its surroundings may have similar temperatures. Nine thermal colour palettes are available for adapting the image to the terrain, weather and viewing task.

The fast F50/1.0 germanium objective provides thermal magnification from 2× to 24×. The low 2× base magnification and wide field of view are ideal for initial detection, while higher digital magnification helps inspect a located subject more closely. The specified thermal detection range is up to 2300 m; actual recognition distance depends on target size, weather, vegetation and the observer’s experience.

4K Digital Channel

The digital channel uses a 3840 × 2160 CMOS sensor with an F50/1.8 objective and a magnification range of 6.5× to 26×. Its field of view is 5.8°, equivalent to 10.2 m at 100 m. It delivers full-colour observation in daylight, retains useful colour information at twilight and supports detailed monochrome observation at night.

In complete darkness, the digital channel is assisted by a focusable 850 nm infrared illuminator with three adjustable power levels. Selecting the lowest effective level reduces reflections from nearby branches, prevents unnecessary image washout and conserves battery power.

Dual-Channel PiP View

Picture-in-Picture mode displays the thermal and digital channels simultaneously. The primary channel fills the main viewing area while the second appears in a smaller window. This makes it possible to use thermal imaging for detection and the 4K digital channel for identification without losing sight of the animal.

Integrated electronic image stabilisation reduces the effect of natural hand movement, especially at high magnification and during video recording. For extended stationary observation, the binoculars include a 1/4-inch tripod socket and an adapter supporting the ARCA-SWISS system.

1500 m Laser Rangefinder

The integrated laser rangefinder measures distances up to 1500 m with stated accuracy of ±1 m. It operates at 905 nm and complies with laser safety Class 1 under IEC 60825-1:2014. True Horizontal Distance indication compensates for the viewing angle, making the measurement more useful on slopes and uneven terrain.

Accurate ranging helps wildlife observers estimate subject size, record field observations and select a suitable photography position without approaching unnecessarily. The rangefinder is also useful during habitat surveys, population counts and structured conservation work.

Technical Specifications

These values correspond to the officially published specifications for the Pulsar Avilume XT50 Pro.

Recording and Connectivity

The Avilume XT50 Pro records photographs and videos with sound through its thermal, full-colour digital and night-vision channels. Recorded resolution is 1440 × 1080 pixels, with JPG used for images and MP4 for video. The built-in 64 GB memory provides substantial storage without requiring a separate memory card.

Audio recording is particularly valuable for bird observation because footage can preserve both visual and vocal identification details. USB-C video output supports external viewing or sharing, while the Wild Vision mobile application enables file transfer, live image streaming and remote control of device settings.

Housing and Power

The magnesium-alloy housing provides structural rigidity for active field use. An IP67 protection rating safeguards the electronics against dust, rain, snow and temporary water immersion. The stated operating range of −25 to +50 °C supports year-round wildlife observation in demanding climates.

Power is supplied by two quick-change APS 5 batteries with a specified capacity of 4900 mAh. Combined operating time is rated at up to 8 hours at 22 °C. Actual runtime depends on ambient temperature and the use of Wi-Fi, the IR illuminator, rangefinder, image stabilisation and recording. A compatible 5 V or 9 V external power source can be connected through USB Type-C.

Field Applications

Birdwatching: The thermal channel helps locate birds among leaves, branches and tall grass where conventional binoculars show a visually complex background. Once detected, the 4K digital channel assists identification by colour, shape and size.

Day and night wildlife observation: Thermal imaging works without visible light and reveals animals in total darkness. When more information about markings or surroundings is required, the digital night channel and adjustable IR illuminator provide additional detail.

Conservation and research: The laser rangefinder, audio recording, 64 GB memory and tripod support are useful for wildlife counts, behavioural documentation and repeatable field observations.

Nature photography: A wide thermal overview helps locate wildlife before it becomes visible to the naked eye. The rangefinder provides a reliable distance reference for selecting a shooting position while minimising disturbance.

Coastal observation: The wide thermal field of view is suitable for scanning shorelines and open landscapes. After exposure to salt spray, the housing should be wiped with a soft, slightly damp cloth.

Setup and Operation

Fully charge both APS 5 batteries before the first field session. Install a battery, adjust the interpupillary distance and set the dioptre adjustment for each eye using the on-screen interface symbols. Focus the selected objective on the observed subject only after completing the eyepiece adjustment.

For rapid scanning, begin with the thermal channel at its base magnification. Once a subject is detected, switch to the digital channel or activate PiP, then use magnification, stabilisation and the rangefinder as required. At night, select the lowest effective IR power to reduce reflections and extend battery life.

A tripod is recommended for prolonged observation and recording. The device has a 1/4-inch socket, and the supplied adapter supports ARCA-SWISS mounting. Connect the binoculars to Wild Vision before regular use to configure wireless functions and check for available firmware updates.

Maintenance

After use, remove moisture and dirt from the housing with a soft cloth. Blow loose dust and sand away from the optical surfaces or remove it with a clean lens brush before using an optical cleaning cloth. Do not use household detergents, abrasive materials or solvents.

For long-term storage, remove the battery, close the objective covers and keep the binoculars in their carrying case in a dry, ventilated location. Before each trip, inspect the lenses, USB-C port, battery contacts and laser rangefinder window.
