Thermion DUO Series

The modern way of hunting

The Thermion Duo DXP50/55 is Pulsar’s first multispectral riflescope. It combines a high-performance European-made thermal imaging sensor with a true-color 4K digital daytime channel.

Rely on the thermal channel’s superb sensitivity for reliable detection, while the digital camera delivers a detailed, full-color image.

Both channels, thermal and digital, are equipped with internal ballistics calculators.

Built on our classic Thermion 2 design, the Thermion Duo DXP50/55 is intuitive, durable, and resistant to heavy wear and tear. It’s designed to serve you reliably for years to come.

Day & night use

For many hunters, the Pulsar Thermion Duo multispectral riflescope is set to become the only option for an optical riflescope at any time of the day and in any weather conditions. The device is based on the best solutions and components used in the development of Pulsar optics to ensure good handling of the challenges of night hunting. Full darkness, rain and fog will not prevent the Thermion Duo DXP from locating a beast and revealing its trophy qualities. The 4K resolution digital channel gives the full colors of day hunting.

4K full-color sensor for daytime hunting

The daytime digital channel clearly draws objects at distances of 10 meters and over. Using the Thermion Duo DXP as a daytime riflescope is always simple and convenient as the lens does not require focusing. The 4K-resolution CMOS sensor provides exemplary detail and identification of objects across the entire range of magnifications. Day hunting is not only comfortable, but also high-tech when using the Thermion Duo DXP. A full-color image peculiar to classic daytime optics is combined with extreme digital functionality. At any time, the hunter can record an image, change the reticle pattern and color, or connect the riflescope to a smartphone.

640x480 @ NETD <25 mK high-sensitivity thermal imaging sensor

A high-sensitivity European-made sensor with < 25 mK NETD captures minimal temperature differences when observing in low temperature contrast conditions, or in rain or fog. The 640 x 480-pixel resolution ensures reliable identification of the target, high-quality visualization of important anatomical features of the animal plus minute details of the surrounding landscape. The sensor’s large size gives the Thermion Duo DXP a wide field of view for comfortable and informative observation of both static and dynamic scenes.

High quality thermal lens

The potential of the high-sensitivity sensor is fully revealed in a thermal imaging channel by the high quality lens. The thermal imaging channel ensures maximum detection efficiency for the hunter in any weather conditions at any time of day.

Advanced image processing: enhanced detail, clarity and contrast

The Thermion Duo implements modern algorithms to reach a new level of image detailing, clarity and contrast. The thermal imaging channel, using a wide range of halftones, has the capability to render complex scenes with evenly emitting low-contrast objects, such as the sky, grass or water surfaces. The enhanced detail and software that sharpens objects at different distances, renders a highly informative thermal image. Manually increasing the sensitivity of the thermal imaging sensor allows you to improve the quality of detection of the animal if observation conditions deteriorate. A smoothing filter and brightness and contrast settings ensure comfort for prolonged observation times. The daytime channel gives ideal image perception in both sunny and cloudy conditions.

Combined multispectral viewing modes

The Thermion Duo supports four observation modes. The digital image mode is used for daytime hunting. The thermal imaging mode is designed for night conditions, and as an auxiliary mode in difficult daytime conditions – fog, dense clouds, rain, oncoming or side sunlight, tall grass, shrubbery and trees in sight may affect the ability to detect an animal. However, the thermal mode allows you to comfortably observe it and clearly determine its trophy characteristics. The “Picture-in-Picture” function in the Thermion Duo makes it possible to simultaneously display images from both optical channels, prioritising the thermal or digital image. This way, Thermion Duo becomes the best multispectral rilfescope for empowering the hunter 24/7.

Automatic transition to low-light mode

When level of light decreases, daylight sensor of Thermion Duo switches into black and white mode. Such transition allows to maintain low noise level, clarity and high definition of digital image in the evening up to sunset.

User mode

Use the brightness and contrast adjustments to maximise the detail and informative value of the image in specific observation conditions. The User Mode function saves selected brightness and contrast settings in the device’s memory providing optimal image quality for the next use of the thermal imager immediately, with no additional adjustments needed.

One-shot freeze zeroing of thermal and digital channels

One cartridge and the Freeze software function are enough to zero in both optical channels at a selected distance. After the ranging shot, the riflescope takes a photo of the target, and the thermal imaging and digital channel reticles are set at the point of impact of the bullet. The Thermion Duo DXP can be zeroed using the base magnification or the zoom, while the click value decreases in proportion to zoom – with maximum magnification the сlick value is less than 0.1 MOA. The aiming point is stable in the full magnification range.
