Balancing performance and price, it is the natural upgrade to elevate your hunt.
Enable seamless transition from rifle-mounted (clip-on or standalone scope) to handheld use. No re-zero required.
Precision Ranging with DNT Ballistic Engine
The HS335R 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.
Sharper Thermal Imaging for Precise Targeting
The HS335R is powered by a 12 µm, ≤18 mK uncooled infrared sensor (384×288), producing crisp, real-time thermal images. Its 35 mm objective lens extends detection distance while maintaining clear target recognition. DNT’s Image Super Resolution (ISR) boosts the sensor to near 640-equivalent, enhancing clarity and preserving fine details. With 3× base magnification and up to 12× digital zoom, it captures every detail even in demanding environments.
Compact, Rugged, Ready for Any Challenge
Compact yet tough, the HS335R 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.
