The RIX Stride ST3 Lite Thermal Monocular is purpose-built for helmet-mounted thermal setups where weight, balance, and mobility matter most.
Designed around a 384×288 resolution, 12µm sensor with <20mK sensitivity, the ST3 Lite delivers clean thermal separation and strong contrast through its 1024×768 OLED display. With a true 1× base magnification, wide 92 ft field of view at 100 yards, and up to 6× digital zoom, it provides real-time situational awareness without tunnel vision.
At just 6.7 ounces, this is one of the lightest helmet mounted thermal monoculars in its class. Detection range is rated at 852 yards (6ft object), giving you the ability to identify heat signatures well before engagement distance.
If your priority is a lightweight, hands-free thermal monocular for night hunting, the ST3 Lite was built specifically for that role.
