Combining Standalone Scope, Clip-On, Handheld Monocular, Laser Rangefinder, and the DNT Ballistic Engine, the HS225R is the most accessible HYDRA-LRF model. Standard with a QDM150 quick-detach mount, it allows effortless switching between handheld scanning and rifle-mounted use. Compact yet capable, it offers unmatched versatility and essential features for those starting their thermal optics journey.
The HS225R integrates a high-precision laser rangefinder capable of measuring distances from 5 to 1,300 yards. Coupled with the DNT Ballistic Engine, it provides instant, accurate drop compensation tailored to the measured range. Ballistic profiles can be adjusted directly on the device or fine-tuned via the DNT App, providing control and adaptability across diverse scenarios.
The HS225R features a 12 µm, ≤25 mK uncooled infrared sensor (256×192) and a 1024×768 Micro-OLED display at 50 Hz, delivering smooth, detailed thermal imaging. DNT’s Image Super Resolution (ISR) boosts the sensor to 384-equivalent, enhancing clarity and preserving fine details. With 3× base magnification and up to 12× digital zoom, it captures precise details even in demanding conditions.
Compact yet tough, the HS225R endures nature’s harshest conditions. IP67-rated and built with a rugged, shock-resistant housing, it handles recoil up to .50 BMG, ensuring reliable performance in rain, snow, or sand.
By connecting your HS225R to your smartphone via the DNT App, you can view the scope’s live feed, manage, edit, and share your thrilling hunts and shooting adventures with friends.
