Pulsar Helion 2 XQ50F

SKU: PUL-77397


The Gold Standard in Thermal Imaging…

With its 384×288, 17µm <40mK thermal sensor, long detection range, high magnification, frost-resistant HD AMOLED display, and all the latest digital functionalities, there’s a reason the Helion 2 XQ50F is the UK’s favourite thermal imaging monocular.

Highly Sensitive Thermal Sensor

The Helion 2 XQ50F features a highly sensitive 384×288, 17µm <40mK thermal imaging sensor which works to present unparalleled detail recognition even in harsh weather conditions such as heavy rain, fog, or snow when thermal contrast is low. This sensor ensures the smallest temperature difference is clearly visible in difficult conditions for a thermal imaging device.

Large Aperture Lens

The Helion 2 XQ50F features a F50/1.0 fast lens to achieve ultimate detection efficiency. Combining this lens with the highly sensitive thermal imaging sensor presents the user with high-quality, detailed, and high contrast imagery, even in harsh conditions.

Long Detection Range

Combining the large aperture lens with the thermal imaging sensor allows the Helion 2 XQ50F to achieve an exceptional detection range of up to 1800m (of a standard 1.8m tall object or animal) in total darkness.

Eight Colour Palettes

The Helion 2 XQ50F features a choice of 8 colour palettes, allowing the user to observe their field of view more effectively and optimise the unit for specific tasks, as well as react to changing observation conditions. White Hot, Black Hot and Red Hot are optimal for object detection, Rainbow and Ultramarine help increase chances for recognition & identification. Red Monochrome, Sepia and Violet are most suitable for long observation in the night.

With Pulsar’s proprietary Image boost technology, the Helion 2 XQ50F uses intuitive software algorithms to increase overall image clarity and detail, resulting in a considerably sharper, more detailed field of view and enhanced object identification capabilities.

The Helion 2 XQ50F features a new 1024×768 full colour HD AMOLED display. Offering improved colour rendering, high contrast imagery, a clear and smooth picture, as well as quick-response and power saving features, this display will always offer a flawlessly high-definition image and a crisp, vividly detailed field of view.

Up to 10 Hours Battery Life

The Helion 2 XQ50F’s quick-detach, rechargeable IPS7, 6.4 A-h battery pack to provide up to 10 hours of operation on maximum mode after only a single charge (depending on temperature). Higher-powered IPS14 battery packs and AA battery cases are also available for this device, providing exceptional off-the-grid power.

External Power Supplies

Charging from an external source such as a power bank is made quick and easy thanks to the Helion 2 XQ50F’s micro-USB jack, enhancing the units power performance during extremely cold weather, whilst still protecting the source from rapid discharge.

Magnesium Alloy Housing

The Helion 2 XQ50F incorporates a magnesium alloy housing to offer high structural integrity and resistance to external mechanical and climactic loads. This housing simultaneously works as a heatsink, removing and dissipating the heat generated by its internal electronics, maintaining the operational stability of the device and ensuring a high-quality image during prolonged periods of observation.

Stadiametric Rangefinder

The Helion 2 XQ50F features a stadiametric rangefinder presented in the shape of a rangefinding reticle, enabling the user to precisely measure the distance of observed objects with known heights, such as deer (1.7m), boar (0.7m), and hare (0.3m).

Built-In Video Recorder

Never miss a moment with the on-board still image and video recorder. Simple to use, just one simple press of the REC button and the Helion 2 XQ50F will capture an or record a video with audio, meaning any once-in-a-lifetime moments can be re-watched and even shared with friends. Images and videos are stored on the integrated 16GB of internal memory.

The built-in Wi-Fi module in the Helion 2 XQ50F allows the user to connect this thermal imaging monocular to their Android or iOS smartphone or tablet using the Stream Vision 2 app. It is good to note, also, that this device is still compatible with the original Stream Vision app.
