Pulsar Krypton 2 FXG50


Introducing the Next Chapter for the Krypton Series

The new Krypton 2 FXG50 ushers in the next stage in the Krypton thermal imaging front attachment’s evolution, with an extremely sensitive 640×480, 12µm, <40mK NETD thermal sensor that guarantees crisp and incredibly detailed thermal imagery at an astonishing range of up to 2300m.


High Definition Thermal Imaging

The next generation Krypton 2 FXG50 thermal imaging front attachment features a highly sensitive 640×480, 12µm, <40 mK NETD thermal sensor, which, when working with the extremely powerful 50mm f1.0 fast aperture germanium objective lens, will provide stunning thermal imagery and an astonishing detection range of up to 2300m in complete darkness.

These powerful optics will enable a user to easily identify an animal and their anatomical features, along with the most minute of details (such as branches, leaves, grass, and terrain) in any weather conditions — working effectively in heavy rain, dense fog, snow, and in environments with high levels of humidity.

Full-HD AMOLED Display

Thermal imagery is presented in crystal-clear detail onto the Krypton 2 FXG50’s new full-HD AMOLED display, offering a high-contrast picture along with a wide dynamic range and energy saving characteristics. This display’s fast response time ensures an image that remains smooth and objects remain well-defined even when in motion or when the device is used in freezing conditions.

Sensitivity Amplification Levels

The Krypton 2 FXG50 offers three sensitivity amplification levels, which, when combined with their new filtration algorithms with fine brightness and contrast adjustments, offer greater identification capabilities in adverse weather conditions and in challenging environments. These sensitivity amplification settings help to better define an animal’s trophy features whilst presenting better rendering of objects and background in the visible field of view.

Compact & Well-Balanced

Taking into account the effect every single extra gram can have whilst hunting, the Krypton 2 FXG50 thermal imaging front attachment has been redesigned to offer a more lightweight bodyshell with a compact footprint that ensures it has minimal impact, when rifle mounted, on the balance of the day optics it is attached to. The new button configuration has been designed to make control of all digital functions as easy to reach as possible.

Bluetooth Remote Control

The ergonomically designed Pulsar BT wireless Bluetooth remote control duplicates the buttons found on the side of this thermal imaging front attachment, allowing users to activate all of the most used functions with ease, and a rotating and pressable encoder enables fast device adjustments and menu navigation. This remote control can be used with both gloved and bare hands, and can be placed in any convenient position on the fore-end or rifle butt, making operation of the device especially convenient for left-handed users.

Magnesium Alloy Housing

A rugged magnesium alloy bodyshell protects the Krypton 2 FXG50 from scrapes, drops, bumps, shocks, and heavy vibration loads whilst working as a heatsink, increasing the operational stability of the device by effectively dissipating any heat caused by the internal electronics.

Adding to its robust characteristics and enhancing its ability to perform well in a myriad of weather and environmental conditions, this thermal imaging front attachment is also IPX7 rated — protecting the device from any water ingress and ensuring it remains operational after a dunk in 1m of water for up to 30 minutes.

This thermal imaging device will remain fully operational in extreme temperatures, providing a reliable performance and excellent thermal informativity in both freezing temperatures reaching down to -25°C and in environments exceeding +50°C.

.375 H&H Ready

High shock resistance allows the Krypton 2 FXG50 to be used with larger calibre hunting rifles such as 9.3х64, .30-06, .300, .375. etc. This device is also perfect for use with smooth-bore air rifles.

Point of Impact Stability

Focus on quick target acquisition and shot placement in low-light conditions with the Krypton 2 FXG50’s point of impact stability; allowing for fast refocusing at various distances through the utilisation of a sequential layout of optical and electronic components designed to provide precise sight alignment and incredibly easy adjustability.

Extended Battery Life

With a rechargeable IPS7 Li-ion battery, the Krypton 2 FXG50 boasts an operation time of up to 11 hours (depending on temperature) — keeping the device running for extended periods of observation and easily remaining operational the whole night through on just a single charge.

Fast & Secure Transformation

The Krypton 2 FXG50 thermal imaging front attachment can be quickly and easily mounted in front of day optics using quick-release PSP-B bayonet adaptors. The device can be removed from one adaptor and installed on another with no need for special tools, allowing the user to turn various daytime optics into a fully-fledged thermal imaging device. A precise screen positioning system also ensures the device is always perfectly aligned with the day optic for guaranteed comfort and fatigue-free prolonged observation.

The Krypton FXG50 can be transformed from a thermal imaging front attachment to a fully-fledged handheld thermal imaging device with the use of the Pulsar 3x20B compact monocular — allowing users to switch between rifle-mounted optics and an ergonomically designed thermal imaging monocular in seconds. This is also available as the Krypton 2 XG50, which includes the monocular as standard.

8 Colour Palettes

Discover a choice of eight colour palettes designed to optimise the observation experience by allowing the device to adapt to specific tasks and achieve the best possible image in ever-changing environments.

For object detection, White Hot, Black Hot, and Red Hot are most effective; Rainbow and Ultramarine is best for object recognition and identification; and Red Monochrome, Sepia, and Violet are most suitable for long observation periods in darkness.

Built-In Still Image & Video Recording

Capture every single memorable moment at just the touch of a button with the Krypton 2 XG50’s built-in still image capture and video recording capabilities. The generous 16GB of on-board storage will allow for hours of video and tens of thousands of still images to be save directly onto the device. An additional 16GB of FREE Cloud storage is offered to all users upon registering to the Pulsar Stream Vision 2 app.

Dual-Band Wi-Fi

The Krypton 2 FXG50’s dual-band Wi-Fi compliments the standard 2.4 GHz smartphone connection frequency range with an effective 5 GHz range, greatly improving the bandwidth — offering faster data transfer, better noise immunity, and improved connection stability. This results in a more productive, easier to use operation when connected to a smartphone.

Stream Vision 2

Connecting this thermal imaging front attachment to the free Stream Vision 2 mobile app provides the user with a variety of intuitive features and functionalities, including the ability to use a mobile phone or tablet as a second screen, remote control of digital functions, viewing and sharing videos and still images, remotely installing all the latest firmware updates, and much more. What’s more, users will receive a generous 16GB of free cloud storage on which to keep their video recordings and still images. Among other intuitive functions, the Stream Vision 2 offers:

  • The ability to use a connected smart device as a wireless remote, so users can control and adjust the device settings. Users can then see all the changes made on the smartphone or tablet screen in real-time. Users are also able to record footage or take still images using the connected device.
  • The ability to browse through all photos and videos recorded on the Krypton 2 FXG50. Users can download and even share these files with friends.
  • The option to remotely update the Krypton 2 FXG50’s firmware, ensuring it is kept up to date and offering all of the latest features and functionalities.
