The DNT Optics HYDRA-Mini HS210M is a 4-in-1 multi-function thermal scope designed for standalone weapon mounting, clip-on integration, handheld detection, and helmet-mounted nocturnal navigation. Built around a 256 × 192 thermal core with a sub-18 mK NETD sensitivity and a 10 mm objective lens, it provides a 17.5° × 13.1° field of view (approximately 30.7 × 23 yards at 100 yards) running at a 50 Hz refresh rate. Weighing 11.3 oz (~320 g), the palm-sized optic is rated for recoil up to .50 BMG and features an IP67 waterproof housing submersible to 1 metre for 30 minutes. Power is supplied by a removable 18650 lithium-ion battery delivering approximately 7 hours of runtime, supported by a 5V USB-C interface for direct charging and data transfer.

Key Features

• 4-in-1 Optical Configuration: Operates as a standalone riflescope, front-mounted thermal clip-on, handheld monocular, or helmet-mounted scanner via standard dovetail bridges (Wilcox or KVC/RQE compatible).
• Thermal Core and AI Processing: Features a 256 × 192 sensor with ≤18 mK thermal sensitivity and AI-powered Image Super Resolution (ISR) processing across 4 colour palettes.
• Recoil-Rated Weapon Integration: Tested to withstand recoil up to .50 BMG and includes a QDF193 Dual Quick-Detach Flip-to-Side Picatinny mount, 65 mm eye relief, 8 reticle patterns, and 5 reticle colours.
• Integrated Media and Connectivity: Includes 32 GB of internal storage, Recoil Activated Video (RAV), onboard audio/video recording, Picture-in-Picture (2×), and Wi-Fi connectivity to the DNT mobile app.
• Power Supply: Operates on a single rechargeable 18650 battery providing up to 7 hours of runtime per cell (two batteries included for up to 14 hours total rotation time).

Who is the Dnt Hydra-Mini Hs210m Multi-Function Thermal Scope for?

• Close-quarters feral pest controllers — requires an ultra-compact weapon optic providing a wide 17.5° × 13.1° field of view and ≤18 mK sensitivity from a 10 mm objective lens for fast target acquisition on pigs and rabbits in dense brush.
• Nocturnal hunters requiring hands-free navigation — requires a lightweight 11.3 oz multi-function thermal scope with native 1× magnification that mounts directly to standard dovetail helmet bridges for unimpeded mobile scanning.
• Shooters utilizing day optics — requires a clip-on thermal unit that mounts forward of low-power daytime rifle sights while sustaining recoil forces up to .50 BMG.

Less suitable for: Long-range target identification beyond close-to-medium distances, or deployment as a clip-on in front of high-magnification day scopes; users requiring extended-range engagement or high optical magnification should choose a dedicated high-resolution thermal scope featuring a larger 384×288 or 640×512 sensor core and a 25 mm or 35 mm objective lens.
