Review the specifications, features and package information before choosing.
The DNT HYDRA HS635 is a versatile 3-in-1 thermal optic that can be used as a standalone thermal scope, clip-on or handheld monocular.
Built around a high-resolution 640×512, 12μm thermal sensor and 35mm objective lens, the HS635 combines excellent image detail with a wide field of view for scanning, hunting and pest-control applications.
3-in-1 Versatility
The HYDRA can quickly transition between handheld scanning and rifle-mounted use with the included QDM150 quick-detach mount. It can also be used as a thermal clip-on with compatible LPVOs and low-magnification prism optics.
Thermal Performance
DNT’s Image Super Resolution (ISR) technology works with the ≤18mK thermal sensor to maintain image detail when digitally magnifying. A 50Hz refresh rate provides smooth viewing when scanning or tracking moving animals.
Built for Field Use
Machined from 6061 aircraft-grade aluminium, the HYDRA is IP67 rated and recoil resistant up to .50 BMG / 800Gs. Built-in WiFi connects with the DNT App for live viewing, recording management and media sharing.
