Introducing the Ultimate Multispectral Powerhouse.

The Symbion LRF DXR50 multispectral binoculars enable complete control over your observation area — no matter the time of day or the weather conditions — combining two advanced optical channels in one premium device:

Thermal Channel:

The Symbion DXR50’s premium 640×480, 12µm thermal sensor will achieve unparalleled levels of thermal contrast, revealing the smallest heat signature through dense foliage at distances reaching up to 2300 m. Its <18mK sNETD thermal sensitivity will effortlessly cut through dense fog, heavy rain, and high humidity — providing exceptional observation capabilities regardless of adverse weather conditions.

4K Digital Channel:

A powerful 4K digital channel provides striking full-colour daytime imaging, clear colour images in twilight and low-light conditions, and high-contrast black & white night vision aided by a built-in IR illuminator — perfect for those who need to start their observations in the day and keep them going long into the night. A built-in, focusable IR illuminator enhances night-time observation even further, extending your detection range and allowing you to pinpoint focus on an object of interest by sliding the convenient IR button at the front of the device.

The combination of these two channels achieves the perfect observation solution, providing a balanced performance across daylight, low-light, and night-time conditions and allowing you to switch between detection and observation at the press of a button.

Combined Observation:

Plus, with Pulsar’s intuitive Picture-in-Picture function, you can even view both channels simultaneously, with a secondary viewing box in the top 10% of the screen allowing for combined detection and observation.

Enhanced Observation: Premium Optics

Both channels are complimented by a powerful 50 mm f1.0 germanium objective lens, providing an impressive 8.8° FOV in the thermal channel and a 5.8° FOV in the digital channel, opening up the observation area and enabling easier detection and inspection with minimal searching and scanning. Closer inspection can be achieved through the Symbion LRF DXR50’s large magnification range (4-32x thermal / 6.5-26x digital), maintaining exceptional image quality throughout.

Confidence in the Field: Next-gen Laser Rangefinder

A built-in next generation laser rangefinder provides a measuring range of up to 1500 m with a accuracy of ±1m, with reliable data allowing you to make informed decisions in the field, establishing the distance between you and your observed object with a press of a button.

Steady & Focused: Electronic Image Stabilisation

Whether you’re tracking fast moving objects, walking rough terrain, or observing your subject from the passenger seat of a moving vehicle, Pulsar’s electronic image stabilisation will ensure a steady image. This feature uses intuitive algorithms to digitally correct the effects of camera shake, achieving a consistently steady image and allowing you to focus on your observations without any distractions.

Adapt to Your Environment: 9 Colour Palettes

Nine colour palettes enable effective observation of the field of view, each of which allow the user to optimise the device for specific scenarios and adapt to changing conditions.

White Hot, Black Hot, and Red Hot are perfect for object detection; Rainbow and Ultramarine will increase recognition and identification capabilities; Sepia, Red Monochrome, and Violet are best for long, night-time observation; and the latest colour palette, Green, mimics the feel of traditional night vision, which is proven to be less stressful on the eye over long periods of observation.

Optimised for One-handed Operation: Control Ring and Focus Knobs

With a striking design, the Symbion features a completely new control array that differs drastically to those found on other Pulsar binoculars. Maintaining the classic design aesthetics of a pair of traditional glass binoculars, the Symbion features a new, ergonomically designed control wheel and focusing knobs — optimising focusing and control over digital functions, navigation of menus, and smooth and convenient zooming for one handed operation.

Designed to Endure: Rugged & Robust Bodyshell

The Symbion’s rugged magnesium alloy bodyshell remains robust, protecting against the everyday bumps, knocks, and scrapes you could come to expect during long periods of observation. With its IP67 rating, these multispectral binos will remain unaffected by adverse weather conditions, including heavy rain, dense fog, snow, and high humidity — allowing you to venture into climates reaching between -25 to +50° without worry about performance.

Added protection to the Symbion’s eyepieces comes in the form of new rubber eyecup covers, guarding against dust when the device is not in use.

Plus, with a ¼” tripod mount included in the box, the Symbion can be placed on a tripod and left to record — perfect for ornithological/ecological surveys, where a hands-off approach is required.

Extended Observation: Up to 10 Hours Battery Life

The Symbion LRF DXR50 will keep you going through the day and into the night, with a removable and rechargeable APS5 battery providing up to 10 hours of battery life (depending on temperature) before a recharge is required.

Never Miss a Moment: Video Recording with Audio

The Symbion is designed to work 24/7, meaning even more opportunity to witness some unmissable moments. That’s why these multispectral binoculars feature built-in image capture and video recording (with audio) capabilities, allowing you to capture your observations and share them with friends or post them on socials.

Images and videos can be stored on the device’s 64GB internal memory, or to the cloud via the Pulsar Stream Vision 2 app for iOS and Android devices.

Enhanced Hands-free Control: Stream Vision 2

Use the Symbion’s dual-band 2.4/5 GHz built-in Wi-Fi to connect to Android & iOS smartphones or tablets using the Stream Vision 2 app. The app offers a wide range of connectivity features, including:

Remote Control: Use a mobile phone as a wireless remote to control and adjust the device’s settings. See all the changes made on your smartphone or tablet screen in real-time. Recording footage or capturing still images can also be achieved using a mobile phone.

Browse & Share: Browse through all photos and videos captured on the device. It is even possible to download and share these files with friends.

Firmware Updates: Download all the latest features and stay up to date by remotely updating the device using Stream Vision’s firmware update abilities, ensuring the device is always running on the most current firmware.
