Meet the all new Stealth Series

Based on the proven performance and popularity of our XD series we thought it was time to take things to a whole new level with the launch of our new XD-II Stealth Series. New models feature improved image quality thanks to the 12μm pixel sensors, greater base magnifications for up to 40% increases in detection ranges, combined with 50% better battery life these units are big improvement.

The units still include built in photo and video recording and now have more memory with 16GB, 1280×960 HD screens, and Wi-Fi on all models as standard (except XD-Mini). The Stealth Series brings some new models with the option of higher resolution 640×512 sensors and the proven and superior image quality of our propriety XST sensors.

The Night Tech Stealth Series XD-II thermal monoculars have been developed for a variety of applications including the outdoors, hunting, marine, security, law enforcement and surveillance.

*Comparable Focal length is based on competitors’ typical focal lengths of F1.2-1.5 and the given lens diameter. The Night Tech Stealth Series uses lower F numbers of between F1.0-F1.2 to reduce the focal length, compared with our competitor’s products that use a higher F number with the same size lens to give a larger focal length number. We have lower F Numbers in order to provide the maximum amount of IR light to the thermal sensor, thus improving the image quality.
