Riflescope with night vision DNT Optics Zulus 4K 3-24x50 LRF

DNT ZULUS 4K 3–24×50 LRF is a digital riflescope with day and night vision function, an integrated laser rangefinder and the ballistic calculator DNT Ballistic Engine. It houses modern electronics in a classic tube body, which in terms of appearance, controls and mounting method resembles a standard optical riflescope. It is intended for hunting, pest control and sport shooting in daylight, at dusk and at night.

During the day it provides a natural colour image, while after dark it can be switched to a black-and-white night mode. This allows it to be used practically continuously without the need to change the scope according to current light conditions.

Functions and features

The core of the riflescope is a Sony STARVIS 2 CMOS sensor with a size of 1/1.8″ and a resolution of 3840×2160 px. In combination with a 50 mm objective lens with an aperture of f/1.8 and ED glass lenses, it provides a fine image with natural contrast. The resulting image is displayed on a fine 1920×1080px 0.49″ Micro-OLED display with a refresh rate of 60 Hz.

The riflescope offers two image modes. 4K mode at 30 frames per second focuses on the maximum amount of detail, offers magnification up to 24× and supports up to 6× lossless digital zoom. Full HD mode at 60 frames per second provides a smoother image, makes it easier to track moving targets and delivers better results in low-light conditions. The shooter can thus choose maximum resolution for observing distant targets, or smoother display when tracking movement.

The sensitive sensor and pixel binning technology make it possible to use the scope at dusk or by moonlight even without an infrared illuminator. IR illuminator is not included. For observation in complete darkness or night shooting at longer distances, the manufacturer recommends using a separate external IR illuminator.

This model is equipped with an integrated laser rangefinder with a range of 5–1300 yards, i.e. up to approximately 1200 metres. The target distance can thus be measured directly through the riflescope without the need to use another device or leave the shooting position. In addition to single measurement, it also supports timed and continuous distance measurement.

The rangefinder is linked to the ballistic calculator DNT Ballistic Engine, which calculates the required correction based on the measured distance and the stored ammunition profile. The result is then displayed directly in the field of view. Two methods are available: Holdover, where a separate correction point is displayed, and Dial-In, where the main aiming point is shifted according to the calculation. Ballistic data can be configured directly in the scope or via the DNT app.

The shooter has at his disposal 9 types of reticles in 5 different colours, so the display can be adapted to the weapon used, the target and the surrounding conditions. Zeroing is made easier by the One-Shot Zero function, which allows the reticle to be electronically shifted to the point of impact. For precise aiming you will also appreciate the Picture-in-Picture mode, which displays a magnified section of the target without the shooter losing awareness of the surrounding area.

The riflescope allows you to record video with sound in a resolution of 4K at 30 fps or Full HD at 60 fps. Recordings are stored in the built-in memory with a capacity of 64 GB, so there is no need to purchase a memory card. In addition to standard recording, there is also the RAV – Recoil Activated Video function, which automatically captures footage before and after the shot once recoil is detected.

Using the integrated Wi-Fi, the scope can be connected to the mobile application DNT. The wireless connection is used to transfer ballistic profiles, display live view, manage stored recordings and transfer them to a mobile phone.

The aircraft-grade aluminium construction is built around a classic 30 mm tube, so the riflescope can be mounted using the supplied or other compatible 30 mm mounting rings. The weight of the scope itself is approximately 690 g and the eye relief is 65 mm. IP67 protection shields the electronics against dust, rain and short-term immersion in water. The riflescope is also rated for recoil up to the level of .50 BMG.

Power is supplied by a replaceable Li-ion battery type 21700 with flat positive pole, which provides up to 6 hours of operation. If necessary, the battery can be quickly replaced directly in the field.
