Purpose and field role

Krypton 2 FXQ35 is a front-mounted thermal attachment that installs on the objective of your daytime riflescope, allowing you to keep your familiar reticle, ballistic setup, and cheek weld while gaining full thermal imaging capability for night and low-visibility shooting. It is ideal for driven hunts, high-seat shooting, stalking in mixed terrain, and tactical training where fast transition from day to night capability is critical.

The device is built for users who operate in real conditions: cold, humidity, fog, light rain, and mixed backgrounds like forests, fields, and hilly terrain, where reliable detection and identification of game or targets is essential.

Thermal sensor and image performance

Krypton 2 FXQ35 is equipped with an uncooled 384×288 thermal sensor with 17 µm pixel pitch and a sensor NETD below 25 mK, while the total system NETD is under 20 mK. This means the device can resolve small temperature differences and show fine image details even in high humidity, fog, drizzle, or after warm days when the background radiates heat.

In practice, this level of sensitivity helps you:

• clearly distinguish animal shape, head, legs, and body orientation;
• identify game species more safely;
• detect partially obscured targets behind branches, grass, or terrain features.

With a 50 Hz frame rate, tracking moving targets remains smooth and comfortable, even during fast shot opportunities in driven hunts or dynamic tactical drills.

Optics, field of view and detection range

The FXQ35 features a fast F35 / 1.0 objective lens, optimized to collect as much thermal radiation as possible with minimal loss, directly improving contrast and image clarity. The attachment itself operates at 1× magnification and works through the optical magnification of your daytime scope, so your perceived magnification is defined by your riflescope’s zoom.

The field of view is 10.7° × 8° (approximately 18.7 × 14 m at 100 m), which strikes a good balance between situational awareness and target discrimination. This makes the FXQ35 particularly suitable for hunting in forests, clearings, and mixed terrain, but still effective for field edges and long rides.

The stated detection range is up to 1350 m for a 1.8 m tall target, providing ample reserve compared to typical shooting distances of 50–300 m. You can see game or human-sized targets entering the field long before they come into your effective shooting range, giving you more time to observe, identify, and decide.

Display and viewing comfort

Inside, the Krypton 2 FXQ35 uses a high-definition AMOLED display with a resolution of 1920×1080. The HD panel delivers a crisp, high-contrast image with wide dynamic range and fast response, which is particularly important in cold conditions where standard displays may slow down or smear.

A sharp, detailed image reduces eye fatigue during long sessions on a high seat or extended observation in tactical or search scenarios. The interface and on-screen information are designed to be compact and non-intrusive, so they don’t block your reticle or interfere with precise aiming through your daytime scope.

A new feature in the Krypton 2 series is graphical user interface adaptation: the user can adjust the position and scale of the device menu and status bar to keep them clearly visible when changing the magnification of the daytime riflescope, ensuring comfortable access to all key status indicators across the full recommended zoom range.

Dual-role device: clip-on + 3× thermal monocular

One of the key advantages of the Krypton 2 FXQ35 is its ability to transform from a clip-on into a standalone thermal monocular in just a few seconds. By attaching the compact Pulsar 3x20B monocular to the bayonet interface, the FXQ35 becomes a handheld thermal device with 3× magnification.

This dual-role capability brings several practical benefits:

• One thermal core, two functions: front attachment for shooting and 3× handheld monocular for observation, tracking, and follow-up.
• During night hunts, you can scan and search with the monocular, then quickly mount the unit back on the scope when you need to shoot.
• For airsoft and tactical users, you can remove the device from the rifle and use it as a handheld observation tool for reconnaissance, route checking, perimeter security, or training.

This modular concept saves money, space, and weight in your gear: instead of carrying a separate thermal scope and thermal monocular, you use one device that covers both roles.

Video recording and connectivity

The Krypron 2 FXQ35 includes an integrated video recorder with photo/video resolution of 912×688, recording in .mp4 and .jpg formats to the built-in 16 GB memory. That is enough for multiple hunting sessions, training runs, or scenario recordings.

Wireless connectivity is handled by:

• Wi-Fi (2.4 / 5 GHz, IEEE 802.11 b/g/n/ac with WPA);
• Bluetooth BLE 4.2.

This allows easy pairing with Pulsar’s Stream Vision 2 app on your smartphone or tablet for:

• live streaming the image;
• managing recordings;
• firmware updates;
• sharing footage with friends, hunting partners, or team members.

For training and tactical sport, recorded footage is especially useful for debriefing, analyzing positions, movement, and shot timing.

Housing, protection and reliability

The body of the Krypton 2 FXQ35 is made from magnesium alloy, combining low weight with high structural rigidity. This ensures stability on high-recoil calibers and increases overall mechanical durability in rugged use.

The device is rated IPX7, meaning it is fully waterproof for immersion up to 1 m depth for a limited time and easily withstands heavy rain, wet snow, and high humidity. The operating temperature range is –25 °C to +50 °C, so it can be used in winter hunts, cold nights near the coast, mountain conditions, and hot summer nights without loss of function.

Compact dimensions (116 × 73 × 83 mm) and a weight of 0.4 kg without battery (0.54 kg with IPS7) help maintain weapon balance, especially when mounted on longer rifles with large objective lenses.

Power system and runtime

Krypton 2 FXQ35 is powered by the IPS7 Li-Ion battery pack with 6400 mAh capacity, providing up to 11 hours of operation at approximately +22 °C. That is enough for a long night hunt, training session, or patrol without changing batteries.

The battery is mounted on top of the unit, improving balance and making it easy to swap even in gloves or darkness. For extended missions, the device supports external power via USB Type-C (5 V or 9 V Power Delivery), allowing you to connect a power bank and keep the unit running for as long as needed.

Mounting, compatibility and zeroing

The thermal attachment is mounted on the objective of your riflescope using dedicated adapters with a four-point bayonet interface. This system provides:

• secure and repeatable positioning;
• alignment of the thermal image with the reticle;
• fast, tool-free installation and removal.

When properly installed on a compatible adapter, the Krypton 2 FXQ35 does not require separate zeroing as a standalone sight. You zero your daytime scope as usual, and the thermal attachment adds thermal imaging to the same optical axis. Once the display is aligned and setup completed once, removing and re-installing the device on the same adapter should not shift your point of impact.

Included remote control (Pulsar BT) can be mounted on the forend or stock, letting you control main functions without moving your support hand or changing your shooting position. Combined with Stream Vision 2, this allows full control over the device both from the weapon and from your phone.

Practical use cases

For hunters:

• Reliable detection and identification of wild boar, deer, fox, and predators in forests, fields, and mixed terrain at night or in fog.
• Use one trusted daytime scope for both day and night, simply adding the thermal attachment when needed.
• Dual-mode use: scan with the 3× monocular configuration, then clip it back onto the scope to take the shot with your familiar reticle.

For airsoft and tactical sport:

• Fast detection of opponents in low light, smoke, or complex terrain.
• Handheld mode for scouting, patrol, and scenario preparation.
• Recording night games or training for later analysis.

For professional and semi-professional use:

• Search and rescue in low visibility;
• Perimeter and infrastructure monitoring;
• Wildlife observation and game management.

Ease of maintenance and operation

Krypton 2 FXQ35 is designed for straightforward operation:

• Controls are arranged for intuitive use in the dark or while wearing gloves.
• The IPS7 battery is quick to remove and replace.
• The lens should be kept clean using a soft cloth; avoid touching it with dirty or abrasive materials.
• Firmware updates are performed via the Stream Vision 2 app, keeping your device up to date with the latest improvements.

As long as installation is done correctly and adapters are properly chosen for your scope’s objective diameter, the device remains stable and predictable, requiring minimal additional adjustments once configured.
