The SYTONG HT-66 NV 850 GE , a dual-use attachment for free hand observation or for attachment to the rifle scope. Thanks to the supplied 45 mm adapter and the bayonet lock used, the device can be mounted on the rifle scope and is ready for use in a very short time. There is no change to the assembly here and the rifle does not have to be zeroed in again.

resolution and image quality
The HT-66 GE has a built-in Sony CMOS sensor and therefore has many advantages. Thanks to the high-quality sensor, the image is reproduced clearly and with little pixelation. The device's 16 mm lens creates a sharp image at various distances. Attaching the device to the eyepiece has the advantage that there is no loss of transmission through the coated lenses compared to the attachment to the objective. The blinding of the eye is prevented by the sensor because the brightness is regulated more quickly automatically. This makes it well suited for use in the forest. Pulling along with moving game is possible here without any problems and there are no image delays. The focusable IR radiator creates a larger detection range and a response of up to 150 m is possible.

display and operation
Another advantage of the device is the OLED display, which can be dimmed down to 10% at the touch of a button. The integrated gyrometer with rotation and inclination angle display is also a functional feature of the device. Another important feature of the device is its silent operation. All keyboard buttons and operating units are rubberized and work quietly. The device has been tested to be bulletproof up to 6000 joules with caliber 9.3 mm and 300 Win Mag. Replacing the SD card is easy and recorded photos and videos can be shared and sent via the in-house app. Thanks to the device's diopter compensation, it can also be used by people who wear glasses without visual aids.

The device weighs just 250 g and therefore has little influence on the overall weight of the rifle.
