The Pulsar Symbion LRF DXR50 is a high-performance multispectral binocular that combines full-colour digital viewing , a powerful 640x480 thermal imaging channel , and an integrated laser rangefinder
into one advanced observation system. Built for demanding field use, it
delivers detailed daytime clarity, strong low-light performance, and
reliable thermal detection when visibility drops, thanks to the sub 35mK NETD thermal sensor (sub 18mK System NETD).
Multispectral Viewing – Digital + Thermal Flexibility
The Symbion LRF DXR50 lets you move instantly between digital imaging and thermal imaging , depending on conditions. It also supports multispectral Picture-in-Picture modes ,
allowing you to keep thermal detection visible while still viewing a
detailed digital image for easier recognition and observation.
Long-Range Thermal Detection
Equipped with a high-spec thermal channel and a large 50mm objective lens ,
the DXR50 is designed for confident scanning across open ground,
woodland edges, and uneven terrain. The thermal view provides strong
contrast and clear heat detection, helping you locate wildlife quickly
even in complete darkness.
Built-In Laser Rangefinder for Accurate Distance Checks
An integrated laser rangefinder gives fast distance
readings at the press of a button, helping you judge range with
confidence. This is ideal for surveying land, monitoring wildlife
movement, and checking distances across fields or valleys without
reaching for additional equipment.
4K Full-Colour Digital Imaging for Day & Twilight
The digital channel features a 4K full-colour sensor ,
producing sharp, natural images for observation in daylight and
twilight. This makes the Symbion DXR50 a true all-in-one binocular for
users who want premium detail without switching devices.
Image Stabilisation for Steady Viewing
Built-in image stabilisation improves comfort and
clarity, helping reduce shake when observing at higher zoom levels or
when scanning for extended periods. It’s especially useful for
one-handed use and long sessions in the field.
Recording with Sound & Easy Playback
Capture your sightings with photo and video recording (with sound)
and store them directly to internal memory for easy review later.
Whether you’re documenting wildlife activity or keeping land management
records, recording is quick and effortless.
App Support & Modern User Interface
Pair the Symbion LRF DXR50 with the Stream Vision 2 app for convenient file transfer, viewing, and control. It also benefits from a new user-friendly graphic interface , making navigation fast and intuitive even when wearing gloves in colder conditions.
Built for Real-World Outdoor Use
Designed for field reliability, the Symbion LRF DXR50 is optimised for one-hand operation
and features a durable build intended for regular use in tough
environments. It’s a strong choice for wildlife observers and outdoor
professionals who want premium multispectral performance in one compact
unit.
