Digital Monocular with Night Vision Attachment Sytong HT-77 LRF

Sytong HT-77 LRF is a digital night vision attachment allowing observation both during the day and at night, equipped with a precise laser rangefinder with a measurement range up to 1000 m.

HT-77 LRF Night Vision Attachment — Digital Night Vision for Day and Night Observation

The attachment features a HD CMOS Sony sensor and a high-quality 1280 × 960 px OLED display with military specifications. This technical specification provides high resolution and smooth image quality, ensuring stable operation even at low temperatures.

The device uses a high-quality SONY CMOS sensor with increased light sensitivity (20% higher than similar competitor models), ensuring comfortable observation at distances up to 300 meters (* with IR illuminator). The latest generation Sony Full HD sensor ensures that the image is much sharper and more detailed day and night. Increased sensor sensitivity allows observation even without IR illumination, significantly reducing the risk of detection.

An undeniable advantage of the OLED display is the brightness adjustment function up to 10% (from extra dark to extra bright). The device allows daytime observation in color and in night mode. User comfort is ensured by the enlarged focus wheel located on the side of the attachment. Optical magnification of 4× can be digitally increased up to 14× (digital magnification 3.5×).

The Sytong HT-77 attachment is not only a telescope or night vision monocular. Using a proper adapter, the night vision device can be mounted on an optical sight (with an eyepiece diameter up to 47 mm). The device has a built-in gyroscope that provides tilt angle information, making the attachment ideal for hunting in mountainous terrain.

Sytong Hunting Night Vision with Laser Rangefinder

The Sytong HT77 LRF night vision attachment has a built-in laser rangefinder, allowing distance measurement up to 1000 m before taking a shot. The rangefinder features high measurement accuracy of ~1 m. However, it should be noted that the rangefinder can only be used at night or in low light conditions. Thanks to this additional feature, the Sytong HT-77 LRF, weighing only 336 g, can be used not only as an observation telescope and night vision monocular, but also as a laser rangefinder for distance measurement.

The Sytong HT-77 is operated using 4 buttons located on the top of the body. Convenient placement combined with a simple interface allows operation even in complete darkness. The night vision device is powered by a replaceable 18650 battery, which can be charged without removal via USB-C. The built-in charging port allows extending operating time using an external power bank. Thanks to the stand-by mode, the Sytong HT-77 has not only extended operating time (up to 6 hours), but also instant device start (~1 second). The side Weaver rail is used to mount the IR emitter.

The manufacturer, of course, did not forget the video recorder function, allowing hunts to be recorded in 1920 × 1080 FHD 30 fps video or in photos with a resolution of 2608 × 1944 5 MP. The device uses a Micro SD/TF card slot supporting media up to 32 GB. Users can also transfer recorded data via WiFi (WLAN).

Despite its lightweight and compact design, the Sytong HT-77 features impressive recoil resistance — up to 6000 J, making it safe to use on hunting firearms of calibers 9.3 × 62 and 375 H&H. The body of the attachment is fully weatherproof according to IPX6 standard.

Included: night vision device, mains charger, USB-C cable, adapter for mounting on a telescope, insulation tape, spare seals, hex keys, protective pouch.

* IR illuminator available separately.
