JSA NIGHT-LUX HOGSEEKER 635 LRF Thermal Imaging Handheld Device

JSA Night-Lux HOGSEEKER 635 LRF – Thermal Imaging Handheld Device with Laser Rangefinder for Maximum Precision

The JSA Night-Lux HOGSEEKER 635 LRF has been specifically designed for hunters who require excellent image quality, a large field of view, and precise distance measurement at short and medium ranges. With its high-resolution 640 × 512 pixel VOx sensor, the fast 35-mm-F0.8 lens, and the integrated laser rangefinder, this thermal imaging handheld device combines state-of-the-art technology with intuitive operation and robust construction.

Whether in the forest, at the bait site, on the stalk, or in the hunting area – the HOGSEEKER 635 LRF delivers high-contrast thermal images even under difficult weather conditions and reliably supports you in safe wildlife observation and identification.
Brilliant thermal imaging quality in any weather

The heart of the HOGSEEKER 635 LRF is the modern 640 × 512 pixel VOx sensor with a pixel size of 12 µm and a thermal sensitivity of ≤15 mK NETD. Even the smallest temperature differences are visibly represented, allowing wildlife to be clearly detected even in rain, fog, high humidity, or dense vegetation.

The high 60 Hz refresh rate ensures smooth and stutter-free representation of moving objects. This is supported by the innovative shutterless system, which nearly completely avoids disruptive image interruptions.

For brilliant image representation, the high-quality 0.49 inch Full-HD OLED display with a resolution of 1,920 × 1,080 pixels provides contrast-rich images with high detail fidelity and allows for longer observations without eye fatigue.
35 mm F0.8 lens for maximum detail recognition

The particularly bright 35-mm-F0.8-lens allows significantly more thermal radiation to reach the sensor than conventional F1.0 lenses. This noticeably improves image quality, especially in difficult weather conditions.

With the 1.5x optical magnification and an effective magnification range of 1.5× to 12×, the device is excellent for observation at short and medium distances. The generous field of view of 21 × 17.5 meters at 100 meters enables quick target acquisition while providing sufficient overview.
Laser Rangefinder up to 1,000 meters

The integrated Laser Rangefinder (LRF) measures distances accurately up to a distance of 1,000 meters. Especially in difficult lighting conditions or in the absence of reference points, this facilitates the safe assessment of distances and supports ethical hunting.
Shutterless-System – Quiet Observation Without Interruptions

The HOGSEEKER 635 LRF operates with a modern shutterless calibration system. While classic thermal imaging devices regularly calibrate audibly and briefly freeze the image, the calibration here occurs almost silently and is hardly noticeable.

Within the first minute, there are only three very short calibrations. Afterwards, the device calibrates automatically about every ten minutes, without noticeably interrupting the observation flow. This way, the game remains in view at all times.
Thoughtful Operation for Hunting Use

All controls have been specifically designed for practical use. The large scroll wheel, the separate confirmation button, and the dedicated photo and video trigger can be operated safely even while wearing gloves. The generous spacing of the buttons allows for error-free operation even in complete darkness.

The large eye relief eyepiece with an eye relief of 1 to 8 cm also provides a complete field of view – even for glasses wearers.
Photo and Video Recording with Wi-Fi

With the integrated 64 GB storage, photos and videos can be saved directly on the device. The built-in Wi-Fi function allows for easy transfer of recordings to a smartphone or tablet. At the same time, software updates can be easily installed via the app.
Robust, weatherproof and built for daily field use

With its robust housing and protection class IP67, the HOGSEEKER 635 LRF is reliably protected against dust and water. Despite its powerful technology, the device weighs only approx. 554 grams and feels comfortable in the hand.

The replaceable 18650 battery allows for a runtime of up to five hours and can be exchanged within seconds if needed.
