Overview
DNT Optics builds the Hydra as a multi-function thermal imager that runs on its own as a rifle scope, clips in front of another optic or is carried as a handheld monocular.
Three ways to use one device, a quick detach mount and spare batteries make it flexible. The sensor is modest in resolution, and runtime and reach data are missing.
Who it's for
Hunters who scan by hand and then mount on a rifle will use the flexibility. Buyers who want fine detail at long distance, or documented runtime, should look elsewhere.
Pros and cons
- Standalone, clip-on and handheld
- Quick detach mount
- Two batteries included
- Flip up cover and eye cup
- Detection range not listed
- Refresh rate missing
- Battery life absent
Performance notes
The thermal sensor detects heat differences, so it works with no light. Low magnification suits scanning and clip-on use in front of a day optic more than distant detail. The quick detach mount lets the unit move between a rifle and hand carry.
