i haven't started a thread in this forum since last Easter, so i'll share a bit about ranging in the dark.
i posted a video to youtube that shows what the Silencerco Radius looks like through a PVS-27 in continuous ranging mode. apologies for the quality, as video was taken via iphone with me just kinda holding it in front of the scope. focus and gain aren't the best i've ever done either. but you can still get the idea.
The LRF is pointed at a plate rack and the plates are 12" 10" 8" 6" (I shot the 4" one off again) and the distance is ballpark 350 yards.
So when the specs say the beam divergence is 0.5 x 1.5 (or 1.85) mil... now, i'm no math major but that ought to be about half again to twice the width of the 12" plate on the left in the video. that's not really what it looks like to me, but may just be bloom or something.
here's the video:

here's the setup i used:
and a couple exciting pics of targets... i shot the rack twice and then missed the 6" plate (pretty sure I was over it) then backed up to 545 or so and shot them again. Then shot the ipsc (visible in video, 2 oclock from plate rack) then the square (10:30 from plate rack) from 615 yards. wind was unusually strong, but at my back, which is good because it didn't push me more than a couple of inches to either side past 600 and it kept the cows bedded down. since you have no peripheral vision when using NV, it's pretty easy for those buggers to surprise you walking into your FOV.
because it's QD and you can use the laser to aim the Radius at night instead of zeroing it with the reticle, you can also easily move it from the gun to a spotting scope assuming it has NV and a pic rail without worrying about it being zeroed on the spotting scope. this is a really effective setup if you've got a buddy.
btw, i ranged all those targets repeatedly in the middle of the afternoon with the Radius and the PLRF10c and every time the Radius read one yard different. I thought that was odd until i realized i was ranging with the PLRF from behind the gun, and the Radius is about 2 feet forward on the front of the scope.
