New for 2021:

Sytong are proud to release the new Sytong HT-77 LRF Night Vision Rear Add On. Sytong have revolutionized the night vision game by adding a 1000-meter range finding function to the device. 

The new Sytong HT-77 LRF is the first digital Night Vision add on that includes an integrated range finder. This new device sets the standard as the most adaptable digital night vision device on the market. You can use the HT-77 LRF as a handheld unit for farming applications or with a simple quarter turn click, attach it to your daytime optic converting it into a night sight ready for hunting.

The large internal screen of the Sytong HT-77 LRF Digital Night Vision Rear Add On with Range Finder produces a high resolution and clear image of your surroundings in full colour during daytime or switch to night mode.

The supplied collar attaches to the eyepiece of your scope and allows you to quickly attach and detach the unit as the shooting conditions change, without any shift in point of impact.

The Sytong HT-77 LRF is supplied in a presentation box complete with a carry bag and all its accessories ready to use.

The standard battery provided with the unit will get the Optic working and useable for a certain amount of time. It is recommended that a separate, higher quality battery is purchased to achieve optimal run time and performance from your unit.
