The DNT Optics Hydra 35mm thermal weapon sight with a 640×512 sensor (DNT part no. HS635) does three jobs in one housing: it runs as a standalone scope, clips on in front of a daytime optic, or comes off the rifle and works as a handheld monocular. DNT Optics pairs a 12 micron sensor rated 18 mK or better with its Image Super Resolution processing, which keeps the picture detailed after you zoom digitally. The housing is CNC machined from a single block of 6061 aircraft-grade aluminum and carries an IP67 rating. A quick-detach mount is included, so moving the sight between rifle and hand does not mean re-zeroing. For hog, predator and night hunters, that flexibility is the reason to look at this model.

Key Specifications

• The thermal sensor is 640×512 at 12 microns, 18 mK or better, which sets the detail you get at range.
• The lens is 35mm, the focal length that defines how much of the scene the sight shows.
• The display is a 1024×768 micro-OLED behind a rapid-adjust eyepiece for a sharp view of the thermal image.
• Eye relief is 2.5 inches (65mm), a forgiving eye box that feels like using a rifle scope.
• The sight weighs 13.7 ounces (389g), light enough to carry handheld or ride on a hunting rifle.
• The housing is CNC machined from a single block of 6061 aircraft-grade aluminum and rated IP67 waterproof.
• Power comes from interchangeable flat-top 18650 batteries, and two are in the box with a charger.
