Like others, I got my first can once I started running thermals. After a year I recently got my paperwork in on a 2nd one, for my wife/son to use on the 2nd thermal gun. I swap it to my day gun and back as needed. My son recently shot his first coyote with my 243 day gun and the lack of recoil and muzzle report surprised him, and for now, I'll just be the pack mule carrying gear to stands and he can pull the trigger!
Only con is the wait time and end cost. But ultimately it's worth every hard earned penny, and I have a feeling I'll have a 3rd soon enough.
