RIX Thermal Monocular - Stride ST3 Lite
RIX STRIDE ST3 Lite is built for hunters and landowners who actually get out and do the hard yards after dark. You’re looking at a true 1× helmet‑mountable thermal monocular with a 384×288 / 12 μm sensor, <20 mK sensitivity and a crisp 1024×768 OLED screen, so heat signatures pop cleanly even in warm, humid conditions. At 190 g and about 4.7 inches long, it’s genuinely lightweight, so you can run it on a lid all night without your neck blowing up. Detection out past roughly 850 yards on a man‑sized target means you’ll see pigs, foxes and two‑legged problems well before they’re in your space. In the paddock it’s simple and effective: base mag is a natural‑feeling 1× for walking and driving, with digital zoom up to 6× when you need to tighten up on a target. The 17.5°×13.1° field of view (about 92 ft at 100 yards) gives you plenty of situational awareness for scanning fence lines, creek beds and crop edges. Power comes from a single removable 18650 with around four hours’ runtime and USB‑C backup, so you’re not stuck when a battery dies. Onboard video, Wi‑Fi app support and 32 GB internal storage make it easy to record and share what you’re seeing, but the real story is in the performance: fast 50 Hz refresh, IP67 build, and controls you can run by feel with gloves on. If you want a no‑nonsense, helmet‑ready thermal that just works in Aussie conditions, the ST3 Lite is a very solid bit of kit.
Key Features
384×288, 12µm thermal sensor with <20mK NETD delivers crisp contrast and reliable target separation in fog, humidity, and low-visibility conditions.
True 1× base magnification with 1–6× zoom lets you move naturally on foot while still having enough magnification for detailed observation when you need it.
Wide 17.5° × 13.1° field of view (about 92 ft at 100 yards) keeps more of your surroundings in view, ideal for scanning paddocks, timber, or fence lines.
1024×768 OLED display provides a sharp, comfortable image that reduces eye strain during long nights behind the glass.
Ultra-light 190 g (6.7 oz) body and compact 120 × 71 × 47 mm housing balance well on a helmet or in the hand, minimising fatigue over long sessions.
Multiple colour palettes and onboard photo/video recording with 32 GB memory let you tailor the view to the terrain and capture footage for review or sharing.
Removable 18650 battery with up to 4 hours runtime plus USB-C external power support keeps the unit running through extended hunts or patrols.
IP67-rated, -20°C to +50°C operating range ensures dependable performance in rain, dust, and the temperature swings common in Australian conditions.
Helmet-mountable design with included adapters gives you true hands-free thermal awareness while driving, walking, or working around the property.
Detection range out to around 780–852 yards on a human-sized target provides early warning of game or intruders well before they reach you.
Features
High-sensitivity 384×288 thermal sensor with <20mK NETD
The STRIDE ST3 Lite uses a 384×288, 12µm thermal sensor with less than 20mK NETD to deliver clean, high-contrast images in challenging conditions. This sensitivity makes it easier to pick out animals, people, and heat trails through fog, light scrub, or humidity. For hunters and landowners, that means more reliable detection when your eyes and visible-light optics are struggling.
True 1× base magnification with wide field of view
With a true 1× base magnification and a 17.5° × 13.1° field of view (around 92 ft at 100 yards), the ST3 Lite preserves natural depth perception while you move. This is especially important for helmet-mounted use, where tunnel vision can cause disorientation or missteps. You still have 1–6× zoom on tap for closer inspection, giving you both situational awareness and the ability to study targets in more detail.
Ultra-lightweight, helmet-ready design
Weighing only about 190 g (6.7 oz) and measuring 120 × 71 × 47 mm, the ST3 Lite is built to disappear on your helmet or in your hand. The low weight reduces neck fatigue during long nights, and the compact length keeps the unit close to the pivot point for better balance. Included helmet-mount adapters make it easy to integrate into a hands-free setup for driving, walking, or scanning on the move.
Sharp 1024×768 OLED display with onboard recording
A 1024×768 OLED display gives you a crisp, comfortable image that’s easy on the eyes during extended observation. Built-in photo and video recording with 32 GB of internal memory lets you document hunts, security events, or wildlife activity without extra gear. Wi‑Fi connectivity and multiple colour palettes add flexibility for reviewing footage, sharing clips, and tailoring the image to your environment.
Rugged, all-weather power and protection
The ST3 Lite runs on a removable 18650 battery for up to 4 hours and supports USB‑C external power, so you can keep it running through long sessions with a spare cell or power bank. An IP67 rating and -20°C to +50°C operating range mean it’s ready for dust, rain, and the temperature swings common in Australian paddocks and bush. This combination of runtime and durability makes it a dependable tool for serious night work.
