RIX Stride ST6 Lite Thermal Monocular – 640 Helmet Mounted Thermal with Extended Detection

The RIX Stride ST6 Lite Thermal Monocular is a high-resolution, helmet-mounted thermal built for hunters and night operators who demand maximum clarity without sacrificing mobility.

Equipped with a 640×512, 12µm sensor and <20mK NETD, the ST6 Lite delivers ultra-clear thermal imaging even in difficult environmental conditions. The crisp 1024×768 OLED display provides sharp contrast and excellent detail, allowing you to identify heat signatures with confidence.

With a true 1× base magnification, wide 17.5° × 13.1° field of view, and adjustable 1–6× magnification, the ST6 Lite maintains natural depth perception while giving you the resolution advantage of a 640 core.

Detection range is rated at 1,300 meters / 1,423 yards (6ft object), making it ideal for open pasture, crop fields, and extended observation.

Despite its performance, it remains lightweight at just 205g (0.45 lb) — fully capable as a helmet-mounted thermal monocular.
