HT-77 LRF, Sytong's digital day/night night vision device with an integrated laser rangefinder with a range of up to 1000m. It can also be used as a spotting scope, surveillance monocular or night vision video recorder, 1920×1080 HD video resolution, 2608×1944 5 mpx photo resolution. It uses a Sony HD CMOS sensor and a high-end 1280×960 px military specification OLED display.
Sensor
For years, some of the world's best sensors have been manufactured by SONY, so it should come as no surprise that the heart of the device is a high-tech HD CMOS sensor from this company. This sensor has a 20% increase in sensitivity (in comparison with similar models from competitors), providing excellent observation quality up to 300 meters (* with IR emitter). The image obtained from this sensor is much sharper and more detailed day and night. In addition, the higher sensitivity of the sensor also allows observation without the IR illuminator, so that the observer can remain almost undetected.
* The IR illuminator with mount is available as an option.
Display
The 1280×960 px military specification OLED display is a high performance display with adjustable brightness from extra dark to extra bright. It provides a color display for daytime observation, and a black and white display for nighttime observation. The 4× optical magnification can be digitally increased to 3.5×, resulting in a 14× digital magnification image.
Rangefinder
The device has an integrated laser rangefinder that allows us to measure the distance to the target within a range of 1000m. Note, however, that the laser rangefinder can only be used at night or in low light conditions.
The built-in rangefinder extends the capabilities of the device, turning it from an observation device into an accurate tool for measuring distances.
Video recorder
The device also has a built-in video recorder function that allows you to capture your observations or hunting trips in a digital version. Movies are recorded in Full HD 1920 × 1080 FHD 30 fps resolution, and photos in 2608 × 1944 5 mpx resolution. The device has a built-in Micro SD/TF memory card slot with a maximum capacity of 32 GB. It is also possible to send materials to the target device using WiFi (WLAN) protocol.
Construction
The body made of high-quality materials provides an impressive resistance to weapon recoil of up to 6000 J, so the sight can be safely used on hunting weapons with calibers 9.3 × 62 and 375 H&H. The large, comfortable focus knob is located on the right side of the unit and allows you to operate it even with thick winter gloves. In the upper part of the device there are 4 large buttons for operation, easy access and simple interface will allow us to operate the device even in total darkness. For mountain hunting lovers a built-in gyroscope will be a useful tool that provides information about the angle of inclination. By using an appropriate adapter (included in the set), we can mount our device on an optical sight (with an eyepiece of diameter up to 47 mm). The attachment is provided by Picatinny socket or thread to the tripod.
Of course, the whole thing is protected against harsh weather conditions and meets the requirements of IPX6 standard.
Power supply
The device is powered by a replaceable 18650 battery. The battery can be recharged without removing it from the night vision scope using the USB-C socket. In addition, this allows you to extend the operating time in the field by charging from a powerbank.
NOTE!!! Please note that you must use the additional IR RADIATOR LAMP on the device, etc. in the dark or at night.
