Pulsar Merger LRF XL50 2.5-20x50 Black Digital Night Vision Binoculars with Laser Rangefinder

The Pulsar Merger LRF XL50 2.5-20x50 digital night vision binoculars with laser rangefinder combine thermal imaging and precision ranging into a single rugged optic—built for hunters, land managers, and tactical professionals who need to identify game and assess distance in low light or darkness. This is a serious tool for extended-range glassing and target confirmation when daylight won't cut it.

At the core is a 1024×768 HD uncooled thermal sensor with sub-40 mK NETD, delivering sharp, stable images across a 2.5–20× magnification range. The 50mm objective lens and wide field of view (14–10.5 degrees at 2.5× zoom, expanding to 24.6–18.5 meters at 100 yards) let you scan large areas quickly without losing detail when you zoom in on a distant animal. The integrated laser rangefinder reaches out to 1,000 meters with ±1-meter accuracy, so you get both the visual confirmation and the distance call in one device—no need to toggle between binoculars and a handheld range finder.

Build and endurance matter in the field. The Merger LRF XL50 houses its electronics in magnesium alloy and meets IP67 waterproof rating, so rain, dust, and cold down to –25°C won't compromise performance. Battery life stretches to 8 hours on a charge, and you get both an external 3,200 mAh swappable pack and an internal 4,000 mAh battery—redundancy means you're never stranded. The 64 GB recorder captures 1024×768 MP4 video and JPG stills; Wi-Fi (2.4/5 GHz) and USB-C fast charging (5V/9V Power Delivery) integrate modern convenience without the complexity.

Eye relief sits at 15 mm with 62–74 mm interpupillary distance adjustment, accommodating most shooters and hunters. The Stream Vision 2 app extends control and playback to your phone. This is a glass-and-electronics investment for serious nocturnal hunting, survey work, or security applications where thermal detection range and rangefinding speed give you a measurable edge.

Frequently Asked Questions

What's the detection range, and how far does the laser rangefinder reach?

The thermal sensor detects subjects over 2,300 meters away under favorable conditions. The integrated laser rangefinder has a maximum measuring range of 1,000 meters with ±1 meter accuracy, so you can locate and measure most hunting or tactical targets within practical use distances.

How long does the battery last, and can I swap batteries in the field?

The Merger LRF XL50 runs for up to 8 hours on a full charge at 22°C. It uses a dual battery system: a 3,200 mAh external battery that you can swap out, plus a 4,000 mAh internal battery. This redundancy means you can change the external pack in the field and keep glassing without powering down entirely. Fast charging is available via USB-C Power Delivery (5V/9V).

Is this binocular waterproof, and will it handle cold weather?

Yes. The Merger LRF XL50 is IP67 waterproof and rated for operating temperatures from –25°C to +50°C. Its magnesium alloy construction and sealed design make it suitable for wet conditions, rain, and harsh environments typical of hunting and professional fieldwork.

Can I record video and share it wirelessly?

The unit includes a built-in 64 GB recorder that captures 1024×768 MP4 video and JPG still images. It supports Wi-Fi (IEEE 802.11 b/g/n/ac on 2.4/5 GHz) and works with the Stream Vision 2 smartphone app, allowing you to control the device, stream, and retrieve footage remotely.
