I can tell you in the west Texas desert that if you are tying to scan 360 degrees with a scope, your going to get dizzy and miss a whole lot of eyes. It was just too much tunnel vision when I tried it. The light made things easier to pick up and while the reflections are brighter with the NV from the eyes, it wasn't any harder to pick out the reflections with the lightforce even with a really low beam strength.
Not knowing where you are headed to hunt, take as much as you can and try it. I went 6 times on my night hunt trips for 3 days each which by no means makes me a pro. But it was easy to see what worked and what didn't. We could cover all 360 degrees with that light in 2-3 seconds and spot animals. Trying that with a scope would be insanely hard to do.
If you really want to find the animals, get a thermal eye or flir for detection. Use the NV then to identify. That will get the ones that won't look at you after you halo them.
I wouldn't scan with a scope at daytime, and certainly wouldn't do it at night in unfamiliar territory.
This is a single kill using nothing but NV. Video recorded grainy on the digisight, but you can see what I mean about looking through the scope for scanning. (The brighter light was the lightforce with IR filter.) Coyote was 75 yards away. Only killed 6 coyotes on that trip, and part of that was getting all the NV figured out and bad weather.
