Figures as published by Pulsar (source). A spec that is not listed is one the maker does not state, not a zero. Detection range is for a 1.8 m object under the maker's conditions; recognition is typically a third of it.
Type: Thermal binoculars Brand: Pulsar
The Merger LRF XL50 uses a 1024×768, 12 µm detector, which has nearly two and a half times the pixels of a 640×480 unit. Sensor NETD is 40 mK (under 20 mK system). The 50 mm F1.0 lens gives 2.5x base magnification, a 14° field of view, digital zoom to 20x and a stated detection range of 2,300 m. A laser rangefinder reads to 1,000 m.
Each eye has a 1024×768 AMOLED display, matching the sensor one to one. It records to 64 GB of internal memory and streams over Wi-Fi. The dual battery system (built-in 4,000 mAh plus a removable APS 3) is rated at 7 hours. The body is IPX7 and weighs 950 g.
It suits users who want the most detail available at long range from a handheld — large estates, open hill, coastal watch — and are prepared to pay for it. In woodland the extra resolution over the XP50 is rarely visible.
