DNT Optics ThermNight 4K Thermal & Night Vision Scope

Arken Zulus ThermNight Multispectral Scope with Laser Rangefinder and Ballistic Calculator

As the latest addition to DNT's best-selling ThermNight series, the TNC4K219R brings enhanced 4K digital day & night vision and advanced thermal imaging together in one multispectral optic. Equipped with a built in laser rangefinder, the DNT Ballistic Engine, and IR illumination, it delivers an all in one solution for fast detection and accurate identification across diverse hunting and shooting scenarios.

Featuring a high sensitivity 12 μm sensor with ≤18 mK NETD, the TNC4K219R captures subtle heat signatures even in complete darkness. Its 2x base magnification and wide 9.2° × 6.9° thermal FOV enhance situational awareness, making close to mid range scanning faster and easier.

The 3840 × 2160 CMOS sensor delivers lifelike imaging with fine detail for more accurate target identification, reducing the risk of misidentification. An integrated IR illuminator ensures visibility in low light conditions for up to 450 yards. Powered by a 8.8° × 4.9° digital FOV, 3–24x magnification, and 3–6x lossless digital zoom, it keeps your perspective wide while delivering sharp, uncompromised clarity at any distance.

Zero once on the digital channel, and the thermal view automatically follows. This intuitive feature eliminates the need for separate adjustments, making setup faster and easier.

With Thermal Zoom Lock, the thermal image stays at base magnification to preserve a wider field of view, while the digital view zooms in for detailed target identification.

With One Tap Connect, the DNT App links the optic and mobile device instantly. Sync custom ballistic profiles, stream live view, manage recordings, and share hunt highlights all at your fingertips.

From dense woodland hunts to dynamic range sessions, the TNC4K219R delivers the clarity, awareness, and versatility needed across changing conditions, day or night.
