Night vision riflescope DNT Optics Zulus 4K 3-24x50 LRF

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

During the day it delivers a natural colour image, while after dark it can be switched to a black-and-white night mode. This allows it to be used virtually continuously, without the need to change the sight 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 the 50 mm objective with an f/1.8 aperture and ED glass lenses, it delivers 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 imaging modes. 4K mode at 30 frames per second focuses on maximum detail, offers magnification up to 24× and supports up to 6× lossless digital zoom. Full HD mode at 60 frames per second provides smoother image, makes it easier to track moving targets and delivers better results in low light. The shooter can therefore 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 sight at dusk or in moonlight even without infrared illuminator. IR illuminator is not included. For observation in complete darkness or for 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 complemented by the DNT Ballistic Engine ballistic calculator, 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. Available methods include 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 sight or via the DNT app.

The shooter has 9 reticle types in 5 different colours available, 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 moved to the point of impact. For precise aiming you will also appreciate the Picture-in-Picture mode, which displays a magnified crop of the target without the shooter losing awareness of the surrounding area.

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

Using the integrated Wi-Fi, the sight can be connected to the DNT mobile app. 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 sight alone is approximately 690 g and the eye relief is 65 mm. IP67 protection shields the electronics from dust, rain and short-term immersion in water. The riflescope is also rated for recoil up to .50 BMG calibre.

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.
