PULSAR PL77458 SYMBION LRF DXR50

The Pulsar Symbion LRF DXR50 is a multispectral thermal binocular that combines thermal imaging, full-color digital night vision, and a built-in laser rangefinder into one compact, field-ready platform. Built for hunters and tactical users who need to see and identify targets in complete darkness, fog, rain, or bright daylight without switching tools, the Symbion LRF DXR50 stacks three imaging modes into a single optic: a 640×480 uncooled thermal sensor optimized for sensitivity, a 4K digital color camera for daylight and low-light work, and real-time rangefinding out to 1,600+ yards. The Picture-in-Picture overlay modes let you see thermal and digital views simultaneously, giving you the context (thermal detection) and detail (color image) needed to make fast, confident shots or tactical decisions in the field.

What sets the DXR50 apart is its thermal-first design: the 640×480 sensor and sub-35mK thermal sensitivity are tuned for hunting-range detection and long-distance target identification, while the 4K digital channel handles everything from daylight scouting to close-range verification. The 4-32× magnification range and 50mm objective work together to pull distant heat signatures into sharp view, and the built-in focusable infrared illuminator extends your effective range in total darkness. A 10-hour battery life, IP67 waterproofing, and magnesium-alloy construction mean this binocular survives the abuse of backcountry hunts and rough field work without flinching.

On-board recording with sound, 64GB internal storage, and Stream Vision 2 mobile app support round out the feature set—you can review footage on the go and stream live video to a smartphone for remote spotting. The redesigned user interface and one-handed operation make the Symbion intuitive to use in gloved or high-stress situations, and the 1440×1080 AMOLED display is bright enough to read in daylight yet easy on battery life. If you hunt predators, hogs, or varmints at night, scout in poor visibility, or need a rangefinding optic that works around the clock, the Symbion LRF DXR50 consolidates the roles of thermal scope, night vision binocular, digital camera, and rangefinder into one tool you can actually carry.

Frequently Asked Questions

Can I use the Symbion LRF DXR50 for both daytime and nighttime hunting?

Yes. The Symbion combines three imaging modes in one: thermal detection for darkness and obscured conditions, 4K digital color imaging for daylight and low-light detail work, and Picture-in-Picture overlay modes that show both simultaneously. This means you can glass in daylight with full color context, switch to thermal for night hunts, and use both views together to confirm targets in challenging light. It works around the clock without tool swapping.

How far can the rangefinder measure?

The built-in laser rangefinder has an effective measurement range of 1,600+ yards, which covers most hunting and field applications. The thermal detection range extends to 2,500+ yards depending on target size and thermal signature, so you can spot distant heat sources well beyond rangefinding distance.

What kind of battery life should I expect in the field?

The Symbion LRF DXR50 delivers 10 hours of runtime on a single APS5 battery charge. You can extend operating time or top up in the field using the 5V USB-C external power option if needed.

Is the Symbion waterproof for use in rain or wet conditions?

Yes. The Symbion LRF DXR50 carries an IP67 waterproof rating and is built with a magnesium-alloy body, making it rugged enough for rain, snow, river crossings, and the general abuse of backcountry hunting.
