Nov 7th 2018 I love this IR Illuminator for my ATN X-Sight 4K Pro! The IR light that comes with the ATN X-Sight is usable, but I was looking for some more detail in longer shots and less wash out with close in shots without having to go into the scope's menu to mess with the light sensitivity setting. I tried a few different IR lights that had low and high settings - but they still weren't what I was looking for. I think Tony Roman from AIrguns: Air Rifles and Pistols has got a great solution with this new Lite-IR-Up 850nm Illuminator. Check it out: https://www.airgunsarp.com/lite-ir-up...
