The Sytong HT-77 is the latest dual-use night vision device from "Sytong". In addition to the familiar features, the HT-77 has an integrated laser rangefinder, which provides precise measurement results up to a range of 600m. Compared to its older brothers, the Sytong HT-77 is also equipped with a larger OLED display with a resolution of 1280 x 960 pixels. The focusing of the unit, like the Picatinny mount for the infrared illuminator, has now been placed on the side.
The HT-77 can be used as a hand-held observation device or, with a few simple adjustments, as a night vision attachment in conjunction with a telescopic sight. The HT-77 is connected to the eyepiece by means of the supplied adapter with bayonet catch (45mm inner diameter). This allows the device to be mounted ready for shooting in seconds. The advantage of the night attachment is that the point of impact does not change after mounting. It is therefore no longer necessary to re-fire the rifle. The effective extension to the rear is only about 9 cm.
The Sytong HT-77 is powered by a replaceable 18650 Li-ion battery, which allows an operating time of about 6 hours. It also comes with other useful features. In addition to the photo and video recording function (micro SD card required), a WLAN function is also available. In conjunction with the corresponding app (iOS & Android), you can transfer, display and save live images on your mobile device.
For use as a hunting attachment, the respective hunting regulations of the federal states apply.
