Sytong Night Vision Device HT-77 LRF

Measuring distance, addressing safely, using flexibly – the HT-77 with LRF

The Sytong HT-77 LRF night vision device – Maximtac German Edition is a modern dual-use night vision device that can be used both handheld for observation and as a night vision attachment on a riflescope. A special feature of this model is the integrated laser rangefinder with a measuring distance of up to 600 meters – a real help in safely assessing distances in the field.

Inside, a Sony CMOS sensor works to deliver a stable, detailed image with significantly reduced pixel structure. The large OLED display with 1280 × 960 pixels ensures clear representation, even during prolonged use. Additionally, a green night vision mode is available, which many users find to be easier on the eyes.

Compared to earlier models, central controls have been revised. The side focusing and the side-mounted Picatinny rail for an external IR illuminator significantly ease handling. Despite the integrated LRF technology, the device remains pleasantly lightweight at only 330 g.

As an attachment device, the HT-77 is mounted on the eyepiece of the riflescope using the included 45-mm adapter with bayonet lock. The installation is quick and recoil-proof. According to the manufacturer, the device is rated for up to 6,000 joules. Re-zeroing is not necessary after mounting. The additional length is only about 9 cm.

Power is supplied by a replaceable 18650 Li-Ion battery with a runtime of up to 7 hours. Photos and videos can be stored on a micro SD card. The integrated Wi-Fi function allows live images to be transmitted and saved via an app on a smartphone or tablet.
