DNT Hydra HS635 640 Thermal Scope – Multi-Function 35mm (Scope / Clip-On / Handheld)
The DNT Optics Hydra HS635 is a compact, multi-function thermal riflescope built for hunters who want versatility, reliability, and strong 640-resolution performance in a lightweight package. Designed to operate as a dedicated thermal scope, clip-on thermal, or handheld monocular, the HS635 adapts easily to different hunting styles and weapon platforms.
At the core is a 640 × 512, 12µm, ≤18mK VOx thermal sensor paired with a 35mm F/1.0 Germanium objective lens, delivering a 1.5x base magnification with excellent detail and contrast. A 1024 × 768 micro-OLED display produces a crisp, high-contrast image, while DNT’s advanced image processing maintains clarity across the entire magnification range.
Power is supplied by non-proprietary 18650 flat-top rechargeable batteries, offering up to 4 hours of runtime per battery, with the option to extend operation using the USB-C external power port. Built for hard field use, the HS635 features an IP67 waterproof and dustproof housing and is rated to withstand recoil up to .50 BMG. Weighing under one pound, it remains compact and well-balanced on virtually any setup.
Additional features include digital zoom up to 8x, onboard photo and video recording with audio, WiFi connectivity through the DNT app, Picture-in-Picture mode, multiple color palettes and reticle options, and 32 GB of internal storage.
All DNT thermal optics are backed by a three-year transferable factory warranty, giving you confidence in long-term performance.
