Digital Monocular Night Vision Attachment Sytong HT-66 850 nm

Digital night vision attachment Sytong HT-66 850 nm with 4× optical magnification allows instant conversion of a daytime scope into a high-class night vision device.

Sytong HT-66 can be used as a scope attachment, standalone observation monocular, or digital night vision camera.

The attachment features a CMOS Sony sensor and a high-class OLED display with military specifications, ensuring high resolution of 1024 × 768 px and clear image quality even at low temperatures. A key advantage of the OLED display is the brightness adjustment function from 10% (from extra dark to extra bright). The device allows observation in full color (daytime) or in night mode supported by a IR illuminator with 850 nm wavelength with 3-level light intensity adjustment. The kit includes an adapter for mounting the attachment on an optical scope eyepiece. Sytong HT-66 does not require re-zeroing after reattachment, allowing convenient use without loss of settings. The device offers 1–3.5× magnification.

Advantages of Sytong HT-66 night vision

The adjustable IR emitter with 850 nm wavelength combined with the latest CMOS SONY sensor with increased light sensitivity (20% higher than similar competitor models) ensures comfortable observation at distances over 200 meters. The increased sensor sensitivity also allows observation without the IR illuminator, significantly reducing the risk of detection.

Operation of the Sytong HT-66 850 nm attachment is managed via 4 buttons located on top of the body, making it easy to operate even in complete darkness. The attachment is powered by a replaceable 18650 battery, which can be charged without removal through a USB-C port. The built-in port also allows extending operating time using an external power bank. Thanks to the stand-by mode, Sytong HT-66 not only has extended battery life but also offers instant start of the attachment in approximately 1 second.

The manufacturer also included a video recorder function, allowing hunting sessions to be recorded in video format with 1440 × 1080 resolution. The device features a Micro SD card slot supporting media up to 32 GB. Users can also transfer recorded data via WiFi (WLAN).

Despite its lightweight and compact design, Sytong HT-66 demonstrates impressive recoil resistance — up to 6000 J, allowing safe use on hunting firearms of calibers 9.3×62 and 375 H&H.
