DNT Optics ThermNight 4K Thermal & Night Vision Multispectral Scope

The DNT ThermNight 4K combines 256×192 thermal imaging, 4K digital day and night vision, a built-in 2,100-yard laser rangefinder, IR illumination, and the DNT Ballistic Engine into one compact multispectral rifle scope.

Officially designated the DNT Optics TNC4K219R, the ThermNight 4K is the newest evolution of DNT’s popular ThermNight platform. It gives hog and coyote hunters the ability to detect with thermal, identify with 4K digital night vision, range the target, and calculate a ballistic solution without changing optics.

The new ThermNight 4K also features a lower base magnification than the original ThermNight TNC225R, with 2X thermal magnification and 3X digital day/night magnification. That wider field of view makes it especially useful for hog hunting, calling coyotes, scanning fields, and hunting in tighter terrain.

256×192 Thermal Imaging with <18mK Sensitivity

The thermal channel of the DNT ThermNight 4K uses a 256×192, 12μm thermal sensor paired with a 19mm objective lens.

With 2X base magnification, the 19mm thermal channel provides a wider field of view for quickly finding heat signatures, following moving animals, and scanning larger areas.

A thermal sensitivity rating of <18mK NETD allows the sensor to recognize small temperature differences, helping maintain thermal detail in humidity, low thermal contrast, and changing weather conditions.

The thermal channel runs at 40 FPS and offers digital magnification from 2X to 8X.

4K Digital Day & Night Vision

One of the biggest upgrades to the DNT ThermNight 4K is its 3840×2160 4K digital imaging sensor.

During the day, the digital channel provides a detailed full-color image. After dark, the digital night vision channel works with the integrated IR illuminator to provide additional detail for nighttime identification.

The digital channel starts at 3X base magnification and offers selectable magnification levels of 3X, 4.5X, 6X, 9X, 12X, 18X, and 24X.

For hunters, the advantage is simple:

Thermal for detection. 4K digital for identification.

You can quickly locate an animal using thermal and then move to the 4K digital channel when you want additional detail before taking the shot.

Thermal + 4K Night Vision in One Scope

The biggest advantage of the DNT ThermNight 4K multispectral scope is having both thermal imaging and digital day/night vision built into one rifle-mounted optic.

Thermal makes it easy to locate hogs, coyotes, and other animals in darkness, shadows, brush, or difficult lighting conditions.

Once the animal is located, the 4K digital channel gives you a more traditional image that can help with positive identification and shot placement.

The ThermNight platform also supports Picture-in-Picture viewing, allowing thermal and digital imaging to work together without requiring two separate rifle-mounted optics.

Built-In 2,100-Yard Laser Rangefinder

The DNT ThermNight 4K features an integrated laser rangefinder rated from approximately 5 to 2,100 yards.

Judging distance at night can be extremely difficult, especially across large fields. The built-in LRF lets you range the target directly through the scope without reaching for a separate rangefinder.

For coyote and hog hunters dealing with animals at constantly changing distances, having the rangefinder built directly into the optic makes the entire process faster and easier.

DNT Ballistic Engine

The integrated DNT Ballistic Engine takes the range information from the laser rangefinder and works with your ballistic profile to provide a shooting solution directly through the optic.

Ballistic profiles can be configured through the DNT Optics App, allowing you to set up the scope for different rifles, calibers, ammunition, and hunting setups.

Range the target, get your ballistic solution, make the correction, and take the shot without needing a separate rangefinder or ballistic calculator.

1920×1080 Micro-OLED Display

Both the thermal and digital imaging channels are viewed through a 1920×1080 Micro-OLED display operating at 60 FPS.

The high-resolution display helps take advantage of the 4K digital sensor while also providing a clean viewing experience when using the thermal channel.

The ThermNight 4K also provides 65mm of eye relief, making it suitable for a wide range of AR-platform and bolt-action hunting rifles.

64GB Internal Recording & DNT Optics App

The DNT Optics ThermNight 4K includes 64GB of internal storage, giving hunters plenty of room to record hunts and save footage directly to the optic.

Built-in Wi-Fi provides connectivity with the DNT Optics App for compatible wireless features, recorded content, and ballistic profile management.

There is no external memory card required before heading to the field.

Replaceable 21700 Battery

The ThermNight 4K is powered by a replaceable 21700 flat-top rechargeable battery with an advertised runtime of approximately 5.5 hours.

The replaceable battery system is a major advantage for long nights of hog and predator hunting. Carry additional charged batteries and swap them as needed instead of relying entirely on a sealed internal battery.

The scope also supports an external 5V USB-C power supply for additional runtime.

Compact 26-Ounce Multispectral Design

Despite combining thermal imaging, 4K digital day/night vision, an IR illuminator, laser rangefinder, ballistic calculator, recording, Wi-Fi, and onboard storage, the DNT ThermNight 4K weighs only 26 ounces.

The optic measures approximately 7.7″ × 3.2″ × 3.1″, keeping the overall package compact enough for both AR-platform rifles and bolt-action hunting setups.

An IP67 rating, 800G shock resistance, and operating temperature range of -4°F to 122°F help make it ready for real-world hunting conditions.
