Sytong HT-660 1x-3.5x Digital Night Vision Rear Add On


In stock (can be backordered)


Like the HT-66, the Sytong HT-660 3.5x Digital Night Vision Rear Add On is a light weight rear mounted night vision add-on that allows you to quickly and easily convert your day scope into a state of the art night vision rifle scope. Whats different to the the HT-66, the HT-660 does not have an inbuilt IR torch. Instead it gives you the option to utilise a more powerful external light source. The HT-660 also features an upgraded 5 megapixel Sony Starvis CMOS sensor with a resolution of 2608×1944

The large internal screen of the Sytong HT-660 3.5x Digital Night Vision Rear Add On 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-660 is compatible with Pard NV007 mounts.

The Sytong HT-660 is supplied in a presentation box complete with a carry bag and all its accessories ready to use.

IR emitter is not permanently installed in the device and can be purchased from us in addition
Longer battery life, as the optionally available IR illuminator is operated with its own battery
The Sytong can still be used where you can no longer see anything with the Pard NV007 without an IR emitter
The screen can be dimmed down to 10% at the push of a button , from “extra dark” to “extra bright”. (With Pard NV007 this is only possible via the menu and only up to 50%)
Integrated gyrometer sensor with rotation and inclination angle display
The sensor can down-regulate the image much faster when the IR heater is switched on, so the eye is not faded
No more fading due to overly focusable IR light, this also makes the use in the forest much more pleasant
According to the manufacturer, the device is recoil proof up to 6000 joules , tested with caliber 9.3×62 mm (Pard NV007S only up to 3800 J)
Own app for live image transmission with direct access to previously saved photos and videos that can be downloaded directly to the smartphone
Better placed buttons simplify operation, especially in manual mode
SD card is much easier to change
