You can't shoot what you can't see. D760 is kinda big and heavy. It can see well only in clear areas with quality light.
Get into animal high weeds, and depending on the animal (deer), you can't see it at all, (pig) you may see black glimpses, (coyote), depending on color, in between deer and pig.
Add an illuminator into the foliage and you have the equivalent of bright headlights in heavy fog, you are (bloomed) washed out blind, can't see through the foliage. And 6x doesn't have a lot of field of view up close. Had a couple of people get rid of 760's for the fov issues.
The ir hunter, unless a solid wall of foliage, they can't hide. 200 and under, absolutely no problem id on the silhouette on any animal. It's light and small enough that you will never want to be without it. There is no field of view issue at 10 yards either.
There is no depth perception with thermal. There is with nv. Only after experience with thermal on known size animals can you begin to judge distance.
On people, when positive identification is required, like policing, or family members in the yard, thermal sucks.
What tnvc said about nv facial id goes,, and I'll add, the lesser nv, the less you identify. The higher quality nv, the better chance you get on id.
I've got a top of the line pvs14, a military issue 3x extender, and a couple of illuminators, depends on the strength needed depends on which illuminator. I've had no problems with required id on animals and learned the limits of the equipment on humans in the 20 odd years I looked at them......
This is the best answer I can give based on your question and limited information you provided.
I've used several much better nv units than the 760, like TaNS, pvs 22, pvs27, aduns, and better thermal units than the ir hunter, like L3 lwts, flir t70 and 75, and would give the same answer above if you substituted the better units on place of 760/ir hunter in your question. They all have the same flaws in use, no matter the quality. It's the distances that the flaw shows up that better units shine.
Best of luck.
