SENTINEL LRF (640) – Military-Grade Long-Range Thermal Binocular
The SENTINEL LRF (640) is a rugged, mission-ready thermal imaging binocular engineered for military operations, including reconnaissance, target acquisition, surveillance, and force protection.
Designed to perform in the most demanding environments, it offers:
– High-resolution uncooled thermal sensor for reliable detection of personnel, vehicles, and equipment through smoke, fog, dust, and camouflage—day or night.
– Integrated eye-safe laser rangefinder with a standard range o f 5,000 meters and an optional extended range of up to 10,000 meters for precise target distance measurement across vast
operational zones.
– Digital magnetic compass (DMC) for accurate azimuth and inclination data—essential for target location, fire correction, and coordinated mission execution.
– All-weather, 24/7 capability, enabling consistent performance in low-visibility or denied environments.
The SENTINEL LRF (640) enhances situational awareness and opera tional effectiveness, providing armed forces with a force-multiplying advantage in tactical and strategic scenarios.
