FD
FD series is the front-end day&night vision clip-on, which is aiming to help hunters to hunt in the night. What’s more, if you change the eyepiece of FD device, it can also be transform into a monocular and rifle scope. FD is a 3-in-1 device.
We only have FD1 and FD1-LRF at present, the difference between them is whether the device has LRF or not.
Normally, calibration is not required. But if the aiming point shifts after you mount the clip-on on the traditional scope, then you need to enter the retical adjustment in the menu to adjust.
