Its high-sensitivity 640×512 sensor with 12 μm pixels, ≤18 mK NETD, and a 35 mm objective lens captures detailed thermal images with exceptional clarity. DNT’s Image Super Resolution (ISR) enhances image quality to a near 960-equivalent level at 6x digital zoom. With 1.5x base magnification and up to 6x digital zoom, it balances broad-area scanning with detailed target observation.

    8 Thermal Color Palettes for Every Environment

    Choose from 8 thermal color palettes to match changing terrain, weather, and background conditions. Whether detecting subtle heat differences or maximizing target contrast, the right palette helps you spot and identify targets more effectively.

    Long-Lasting Power in a Compact, Rugged Package

    At just 15 oz (424 g), the HS635R is built for all-day carry. Two rechargeable batteries provide up to 8 hours of total runtime (4 h per battery), while its IP67-rated, shock-resistant housing withstands recoil up to .50 BMG. Built for demanding hunts from wooded terrain to open fields, it balances field of view and long-range capability for a wide variety of hunting environments.

    Everything picture wise is great about this thermal

    Everything picture wise is great about this thermal, love it. Easy to setup and dial in. Only thing that i think could be improved is the screw in battery cap. I have had trouble getting it started when out in the field .

    amazing!

    used to have the hs325r which was great but wanted to upgrade. haven’t even hunted with it yet just look through it and it is crystal clear and you can see a lot more since its base is 1.5x

    The best thermal on the market hands down

    the best thermal on the market hands down. Its very scary accurate if you dial in your ballistics calculator. I can hit the smallest steel target at 300 yards with my 223 no problem. It makes everyting else look way overpriced. Pulsar and AGM have some thinking to do to be bale to compete with these guys long term.

    The hydra HS 635R is an awesome 3 in 1 optic

    The hydra HS 635R is an awesome 3 in 1 optic. I love how small of a profile it is. Quality is excellent in fact I feel like it was on par with my buddies more expensive thermal. He is actually thinking of selling his and getting the hs635r simply because of the size and features.

    To start I ordered the wrong optic…

    To start I ordered the wrong optic. I received it quickly, checked it out and The 3x magnification was too much. I contacted them, returned the optic and mount, the refunded as soon as they had my full return. I ordered my 635 lrf, it came in promptly in great condition. The optic itself is excellent. At this price point my opinion this is a solid excellent thermal. I have zero complaints, love the company the product and the customer service with dnt.
