Supporting More Humane Deer Management: Pulsar Symbion LRF DXT50 & DXR50
Effective deer management depends on making informed, responsible decisions in the field. Locating deer is only part of the process. Understanding what you are looking at, assessing the animal and the wider group, establishing an accurate distance and considering the surrounding environment are all important before deciding whether a shot is appropriate.
The Pulsar Symbion LRF series has been developed around this need for information, bringing thermal imaging, 4K digital day optics, digital night vision and laser rangefinding together in a single multispectral binocular.
Available in two models – the Pulsar Symbion LRF DXR50 and flagship Pulsar Symbion LRF DXT50 – the Symbion gives professional deer managers and stalkers the ability to detect, observe and assess deer across changing light and weather conditions without continually swapping between separate devices.
Detect First. Assess Before Acting.
Thermal imaging has transformed the way deer can be located and monitored, particularly across woodland margins, forestry, open hill and other environments where conventional optics can struggle.
Both Pulsar Symbion models feature a 50mm F1.0 thermal objective lens and provide a quoted thermal detection range of up to 2300 metres. This gives the deer manager the opportunity to locate heat signatures across large areas and begin observing animals from a considerable distance.
Thermal can also help reveal animals that might otherwise be difficult to locate against complicated backgrounds or in poor visibility.
Crucially, however, detecting an animal and positively assessing it are two different things.
This is where the multispectral design of the Pulsar Symbion becomes particularly valuable.
Rather than relying solely on a thermal image, the user can move between the thermal and high-resolution digital channels, using the strengths of each technology as conditions and the observation requirement change.

Pulsar Symbion LRF DXT50 – HD Thermal Detail
At the top of the range sits the Pulsar Symbion LRF DXT50, built around a premium 1280 × 1024, 12µm thermal sensor paired with a 50mm F1.0 objective lens.
The move to 1280-resolution HD thermal provides considerably more image information than conventional 640-class thermal sensors. For deer management, that additional resolution can be especially useful when observing animals in more complicated environments or when greater thermal detail is required.
The DXT50 offers a thermal detection range of up to 2300 metres, allowing large areas to be scanned efficiently before the user moves closer for more detailed observation.
Once deer have been located thermally, the Symbion's 4K digital channel provides detailed full-colour daytime observation. As available light disappears, its digital night-vision capability and integrated focusable infrared illuminator allow observation to continue into darkness.
The result is effectively three observation technologies within one binocular: HD thermal imaging, 4K digital day observation and digital night vision.
Pulsar Symbion LRF DXR50 – 640 Thermal Performance
The Pulsar Symbion LRF DXR50 provides the same multispectral concept but uses a 640 × 480, 12µm thermal sensor.
Combined with its 50mm F1.0 objective lens, the DXR50 delivers a quoted thermal detection range of up to 2300 metres, with 4–32× thermal magnification and a horizontal thermal field of view of approximately 8.8°, equivalent to 15.4 metres at 100 metres.
Like the DXT50, the DXR50 combines this thermal channel with 4K full-colour digital imaging, allowing the user to move from rapid thermal detection to a more natural digital image for closer observation and assessment.
Image stabilisation further assists observation, particularly when using increased magnification or viewing an animal for an extended period.
For deer managers who want the advantages of the Symbion multispectral platform but do not require the 1280×1024 HD thermal resolution of the DXT50, the DXR50 provides a highly capable 640-resolution alternative.
DXT50 vs DXR50 – What's the Difference?
The biggest difference between the two Pulsar Symbion models is the resolution of their thermal channels.
Pulsar Symbion LRF DXT50
- 1280 × 1024, 12µm HD thermal sensor
- 50mm F1.0 thermal objective
- Up to 2300m thermal detection range
- 4K digital day and night observation
- Integrated laser rangefinder
- 1920 × 1080 AMOLED display
- 64GB internal memory
Pulsar Symbion LRF DXR50
- 640 × 480, 12µm thermal sensor
- <35mK sensor NETD / <18mK System NETD
- 50mm F1.0 thermal objective
- Up to 2300m thermal detection range
- 4–32× thermal magnification
- 4K digital day and night observation
- Integrated laser rangefinder
- 1920 × 1080 AMOLED display
- 64GB internal memory
Both therefore offer serious long-range detection capability. The principal performance step with the DXT50 is its 1280 × 1024 thermal resolution, providing four times the thermal pixel count of a 640 × 480 detector.
For users who spend considerable time observing through thermal, particularly where identifying finer detail at distance is important, that increase in resolution represents a significant advantage.

Accurate Range – Without Changing Equipment
Both Symbion models also incorporate a laser rangefinder, removing the need to put down the binocular and reach for a separate rangefinding device.
The DXT50's integrated LRF provides measurements out to 1500 metres with quoted ±1m accuracy, giving the user immediate information about the distance to an animal, feature or point within the landscape.
For professional deer management, knowing distance accurately contributes to a much more complete understanding of the situation being observed.
Instead of estimating range from an image alone, the user can detect with thermal, assess through the digital channel and establish distance from the same observation platform.
Supporting More Selective Deer Management
Technology cannot make deer-management decisions for the person behind the binoculars, but it can provide considerably more information on which to base those decisions.
Thermal imaging can help locate animals that conventional optics may miss. Digital optics can provide additional visual information for assessment. Night vision extends observation beyond daylight, while an integrated laser rangefinder provides an accurate measurement of distance.
Used together, these technologies can support a more considered approach to deer management – giving the user more opportunity to observe the individual animal, consider the wider group and assess the surrounding environment before deciding whether taking a shot is appropriate.
There are also situations where the additional information reveals that the correct decision is not to shoot.
That ability to observe first and act second is where multispectral technology has the potential to make a meaningful contribution to responsible deer management.
One Binocular From Daylight to Darkness
The other significant advantage of the Pulsar Symbion concept is simplicity.
A deer manager may traditionally carry conventional binoculars, a thermal monocular, a night-vision device and a separate laser rangefinder. Symbion brings these observation capabilities together within a single field-ready platform.
Both models also incorporate a 1920 × 1080 AMOLED display, 64GB internal memory, photo and video recording, Wi-Fi connectivity and Bluetooth, while their digital functionality allows observations to be recorded for later review.
For professional deer managers, estates and stalkers spending long periods in the field, having detection, observation and rangefinding available through one familiar device can significantly simplify the observation process.
Which Pulsar Symbion Is Right for You?
The Pulsar Symbion LRF DXR50 brings the Symbion concept to a high-performance 640×480 thermal platform, combining long-range thermal detection with 4K digital observation and integrated laser rangefinding.
The Pulsar Symbion LRF DXT50 takes the concept further with its 1280×1024 HD thermal sensor, providing substantially greater thermal image resolution for users wanting the highest level of detail available from the Symbion range.
Whichever model suits the application, the principle remains the same: detect with thermal, observe and assess with multispectral imaging, accurately establish distance and gather as much information as possible before taking action.
For modern deer management, that combination can support safer, more selective and ultimately more humane decision-making in the field.
