Rix Optics Stride ST3 Lite

• True 1x thermal viewing: The 1.00 x base magnification gives the Rix Optics Stride ST3 Lite a natural viewing perspective that is easier to use while scanning, moving, or observing at short to medium distances than a higher native magnification.
• 384x288 sensor with 12.00 μm pixels: This sensor format balances detail, detection capability, and compact size, helping the monocular show heat signatures clearly while keeping the unit light enough for extended handheld use.
• 20.00 mK NETD sensitivity: High thermal sensitivity improves separation between small temperature differences, which helps reveal animals, people, and terrain features more distinctly in humid weather or low-contrast conditions.
• Compact 190.00 g housing: With a weight of just 190.00 g and dimensions of 120.00 mm in length, the monocular is easy to carry in a pocket or pack and less tiring to hold during long observation sessions.
• WiFi, recording, and USB-C power: Built-in Wifi, photo and video capture, and a USB-C port make it easier to save observations, share the live view, and keep the device powered in the field.

About the Rix Optics Stride Series

The Rix Optics Stride series is a family of thermal-imaging monoculars built for users who want a compact handheld thermal device rather than a dedicated weapon sight. Within the RIX lineup, the series sits alongside the company’s thermal riflescopes and other thermal monocular families, giving hunters, landowners, and general outdoor users a lighter platform for scanning, detection, and observation. The series focuses on practical field use: compact dimensions, simple controls, onboard recording, wireless connectivity, and weather-resistant construction.

A defining trait of the Stride series is its emphasis on mobility. These monoculars are designed around a short, lightweight form factor that is easier to carry for long periods and quicker to deploy when checking tree lines, fields, trails, or property boundaries. Thermal imaging allows the user to detect heat signatures independently of visible light, which makes the series useful after dark, at dawn, and in visually cluttered environments where conventional optics can miss movement. Depending on model, the series combines different sensor resolutions with a straightforward viewing system, OLED display technology, and digital functions such as image capture, video recording, and app-based connectivity.

About the Rix Optics Stride ST3 Lite

The Rix Optics Stride ST3 Lite is the lighter-entry configuration in the series, built around a 384x288 thermal sensor with 12.00 μm pixel pitch and a highly sensitive 20.00 mK NETD. In practical use, that combination gives the monocular enough detail for confident detection while keeping cost, size, and weight under control. The stated 780.00 m detection range makes it suitable for spotting heat sources well beyond normal handheld observation distances, while the 50.00 Hz refresh rate helps motion appear smoother when scanning moving animals or sweeping across terrain.

Its viewing setup is especially important. The 1.00 x minimum magnification gives a more natural image scale than many compact thermal devices, which is useful when scanning nearby ground or maintaining spatial awareness. Digital magnification extends the range up to 6.00 x when more target detail is needed, while the 25.00 mm objective and F 1.0 aperture support efficient heat collection. The OLED display with 1024×768 resolution provides a crisp viewing surface for the thermal image, and the -5D to +5D diopter adjustment helps users tune the image to their eyesight.

Field handling is another strength of this model. At 190.00 g, the ST3 Lite is easy to carry for long periods, and its waterproof, fogproof, and shock-resistant construction is better suited to outdoor use than a delicate observation device. Built-in Wifi, photo capture, video recording, video output, and USB-C charging add practical flexibility for documenting observations, connecting to external devices, and keeping the monocular running with modern power accessories.

About Rix Optics

RIX Optics is based in Richardson, Texas, United States. The company focuses on thermal-imaging and night-vision optics and builds a catalog that includes thermal riflescopes, thermal monoculars, and digital day-and-night-vision scopes. Its product families are organized by use case, with the STRIDE series dedicated to thermal-imaging monoculars and other lines covering riflescopes and more specialized thermal devices.

Within that range, RIX has developed several distinct platforms. The LEAP series includes thermal riflescopes with continuous optical zoom and built-in laser rangefinders, while some STORM series models also integrate laser rangefinders. The company also offers the POCKET series of thermal monoculars with 256- and 384-resolution sensor options. This focus on dedicated thermal and night-vision products gives RIX Optics a clear specialization in observation and hunting optics rather than a broad general-optics catalog.
