DNT ThermNight 4K 219R Tested: Day, Night, and Thermal in One Scope
Multispectral optics that blend daylight, digital night vision, and thermal into one housing usually come with a price tag to match. In a video from sootch00, the host runs through the DNT Optics ThermNight 4K 219R, a new entry-level model in DNT's Thermion line, and walks through its controls and imaging modes before taking it outside to see how each one actually performs.
Snapshot
Sootch00 treats the 219R as three optics in one: a 4K daylight scope, a PVS-14-style digital night vision mode with IR illumination, and a dedicated thermal channel. He says DNT has built a reputation for strong thermal gear at reasonable prices, and argues this model extends that value into a combined day/night/thermal package without a noticeable drop in image quality.
Key points
- Imaging specs: The daylight side uses a 3840x2160 4K sensor running 3x-24x, while thermal runs a 2056x192 sensor at 2x-8x, with four color palettes including white hot and black hot.
- Night vision mode: A removable IR illuminator powers the digital night setting only, switchable from daylight with a button press, similar to an analog PVS-14 setup.
- Rangefinder and zeroing: A built-in laser rangefinder reads out to 2,100 yards, and the scope supports one-shot zeroing after firing a single round.
- Battery and durability: It runs on a 21700 lithium-ion cell rated for about 5 hours 45 minutes, includes a spare battery, 64GB storage, Wi-Fi, and is IPX7 waterproof rated.
- Range demo: Outdoors, sootch00 shows clear focus and target identification at roughly 40 and 85 yards across daylight, night, and thermal modes, including picture-in-picture switching between them.
Quick take
Sootch00's main point is that the ThermNight 4K 219R packs legitimate three-mode capability into a budget-friendly package, with enough range, battery life, and image clarity to matter for hunters or anyone wanting one optic that covers day, night, and heat signature detection.
