The Pard NV007V is an updated version of the previous NV007A model. Reasonable price and good quality are combined in this device. The NV007S is an infrared device that can be attached to the eyepiece of a rifle scope with a quick-mount adapter. Add and remove a device from your scope; you don't have to align the sight, and you don't have to repeatedly work with external sleeves. The device can be used both during the day and at night. The device has a sharp, high-quality Sony Oled HD screen.
