Pulsar Merger LRF Thermal Binocular
The Pulsar Merger is a true two-eyed thermal binocular with a built-in laser rangefinder, made for hunters and observers who glass for hours and want relaxed, stable viewing instead of squinting through a monocular. The XP35 and XQ35 keep it compact; the XP50 and XT50 add bigger sensors and lenses for longer range and finer detail.
Pros
- True two-eyed viewing reduces eye strain on long glassing sessions
- Built-in laser rangefinder on every LRF variant
- XT50 HD 1280x1024 / 12µm sensor with stated 2,500-yard detection
- Image stabilization and lossless image transfer on higher models
- On-board recording with 64GB storage on the XT50 and Stream Vision 2 Wi-Fi
Cons
- Heavier and more expensive than a single monocular of the same class
- Bulkier to carry and stow than a pocket device
- Observation only; not a recoil-rated riflescope
- Top XT50 sensor pushes the price toward flagship territory
What the Merger is and why a binocular
Unlike a monocular you hold to one eye, the Merger uses two displays and two eyepieces, so you observe with both eyes open. That reduces eye strain on long watches and gives a more natural, immersive view of the scene, which is the main reason to choose it over a comparable monocular. It sits at the top of Pulsar's handheld observation line alongside the Telos monocular, trading some pocketability for comfort.
Every Merger LRF variant carries an integrated rangefinder, and the higher models add image stabilization. On the XT50, lossless pixel-to-pixel image transfer and stabilization keep the picture steady and crisp even at higher zoom, which matters when you are reading detail at the edge of detection range.
Sensor and variant options
Mergers are named by sensor and objective. The practical lineup runs:
- Merger LRF XQ35 / XP35 - the compact pair. XQ35 uses a 384x288 core; XP35 steps up toward 640x480 on a 35mm lens for a lighter long-watch binocular.
- Merger LRF XP50 - a 640x480 sensor on a 50mm lens with 2.5-20x magnification, the long-range all-rounder.
- Merger LRF XT50 - a 1280x1024 / 12µm HD core on 50mm, the sharpest and longest-reaching option.
The XT50's HD sensor detects hot objects out to a stated 2,500 yards and ranges to 1,640 yards, while even the 640x480 cores capture minimal temperature differences in rain, fog, or low contrast. Higher resolution and a finer 12µm pitch are what separate the detail of the XT50 from the lower variants, which is reflected in our Pulsar price guide.

Rangefinder, recording, and connectivity
The built-in laser rangefinder is the headline feature for hunters: on the XT50 it ranges to 1,640 yards, so you confirm distance to an animal without a second device. On-board recording captures photo and video, and the XT50 adds 64GB of internal memory to store footage from long sessions.
Built-in Wi-Fi links the Merger to Android and iOS phones through the Stream Vision 2 app, which streams the live view, transfers files, updates firmware, and lets you control the device remotely. This is the same ecosystem used across Pulsar's thermal line, so the workflow carries over if you also run a Pulsar scope.
Honest limits and who should consider a sibling
A binocular is larger, heavier, and pricier than a single-eye device of the same sensor class, so the Merger is not the pick if budget or packability lead your list. A buyer who wants long-range observation in a smaller, lighter package should look at the Telos monocular; a buyer who wants a pocket scanner should drop to the Axion 2. The Merger is also an observation device, not a riflescope, so it is not meant to be mounted on a rifle.
Within the binocular family, the older Accolade line covers a similar role at a different point, so it is worth comparing. For a ranked view across two-eyed options, see our best thermal binoculars shortlist and the broader thermal binoculars overview.

Frequently Asked Questions
What is the difference between the Merger XP50 and XT50?
The XP50 uses a 640x480 sensor, while the XT50 steps up to a 1280x1024 / 12µm HD sensor for sharper detail, a stated 2,500-yard detection range, and 64GB of built-in recording memory. The XT50 is the sharpest and longest-reaching Merger; the XP50 is the lighter-cost long-range option.
How far can the Merger range and detect?
On the XT50, the built-in laser rangefinder reaches up to 1,640 yards and the sensor detects hot objects out to about 2,500 yards. Lower variants detect and range shorter distances in line with their smaller sensors and lenses.
Is the Merger better than the Telos?
Neither is strictly better; they answer different needs. The Merger is a two-eyed binocular that is easier on the eyes for long observation, while the Telos is a lighter, more packable monocular. Choose the Merger for comfort on extended watches and the Telos for portability.
Does the Merger connect to a phone?
Yes. Built-in Wi-Fi links it to Android and iOS devices through the Stream Vision 2 app for live streaming, file transfer, remote control, and firmware updates.
Can I mount the Merger on a rifle?
No. The Merger is a handheld observation binocular and is not recoil-rated for mounting. For an aiming device, look at Pulsar's thermal riflescope line instead.
