Pulsar Merger Duo NXP50 PL77455 Thermal Imaging Binoculars

The Pulsar Merger Duo NXP50 is a dual-sensor thermal imaging binocular that combines uncooled microbolometric thermal detection with a full-HD digital camera in one rugged platform. Built for hunters, law enforcement, and serious night operators who need to see and record in complete darkness, this is the kind of versatile glass that performs when conditions get real. The thermal channel reaches out to 1800 meters for target detection, while the digital channel captures what you're seeing in high resolution, making it equally at home on a stand, behind a rifle, or glassed to a chest rig.

What sets the Merger Duo apart is the dual-lens design: a fast F1.0 thermal objective paired with an F1.4 digital lens, both 50mm. Thermal magnification ranges from 3x to 24x; the digital runs 1.5x to 12x. You're looking at an AMOLED HD display showing 1280x960 pixels, which means crisp, detailed sight pictures in low light. The 17-micrometer thermal sensor delivers better than 25mK sensitivity, so you'll distinguish animals and people from their surroundings with clarity. Eye relief sits at 12mm—comfortable for glasses wearers and quick target acquisition.

Battery life is rated at 7.5 hours on the dual Li-Ion system: a swappable 3200mAh external pack plus a 4000mAh internal battery, both charged via USB Type-C Power Delivery (5V or 9V). The magnesium-alloy body is sealed to IP7 (waterproof), rated to operate from –25°C to +50°C. Recording capability is native: video in MP4 and stills in JPG direct to onboard storage, with Wi-Fi (802.11ac) for wireless transfer to a phone or tablet. Weighing 1.2 kg with batteries, it's built for extended field use without wearing you down.

The 940nm IR illuminator (500mW output, invisible to the naked eye) enhances the digital channel in moonless conditions. Beam position is adjustable, letting you dial in IR coverage to match your zoom level. This is professional-grade gear for hunting, security work, and applications where thermal advantage and documentation matter.

Frequently Asked Questions

Can I use these thermal imaging binoculars for hunting?

Yes. The Merger Duo NXP50 is designed for hunting applications. The 1800-meter thermal detection range and fast optics allow you to locate game in darkness or low-light conditions. The dual magnification ranges give you flexibility to glass wide areas at lower power or zoom in on distant targets. The fast F1.0 thermal and F1.4 digital lenses gather light efficiently in low-light hunts.

What battery system does it use, and how long will it last in the field?

The Merger Duo uses a dual Li-Ion battery system: a removable 3200mAh external APS 3 battery and a 4000mAh internal battery. Together, they provide up to 7.5 hours of runtime at 22°C. You can swap out the external battery in the field to extend use, and both batteries charge via USB Type-C Power Delivery (5V or 9V input).

Will the IR illuminator be visible to others, and can I adjust it?

The IR illuminator operates at 940nm wavelength, which is invisible to the naked human eye. The 500mW output enhances the digital channel's performance in moonless conditions. Yes, the IR spot position is adjustable, allowing you to dial in coverage to match your current magnification level.

Can I record video and transfer it to my phone?

Yes. The Merger Duo records video in MP4 format and captures photos as JPG files at 1280×960 resolution, stored internally. Built-in Wi-Fi (802.11ac) allows you to wirelessly transfer your video and photo files to a smartphone or tablet for review, sharing, or evidence documentation.

What's the waterproof rating, and can I use it in harsh weather?

The binocular is sealed to IP7 rating, meaning it's waterproof. It's rated to operate across a wide temperature range: –25°C to +50°C. This makes it suitable for extended use in rain, snow, and extreme field conditions common to hunting and security operations.
