Binos and my range finder are used on each and every stand.
When I sit down, before I make a sound, I glass the area. Many times I have spotted a coyote way out there, looking right at me. I figure he watched me walk in and sit down. I won't call to that coyote because I do not want him to put 2+2 together.
Instead, I will watch that coyote until he walks out of sight, wait several minutes, and then start calling.
Edited to add: I only hunt public land, and perhaps my coyotes are a little more spooky?
Before I stand up at the end of a stand, I will glass again. Many times I have spotted coyotes on the way in, or just see their head, looking at me over a Sage or Yucca bush 300yds out.
Here in the wide open West, the rangefinder has helped me connect on numerous coyotes that hang up at 300-400+ yards. Knowing the range precisely allows me to make long range hits.
So for me, yes to using binos and a rangefinder. Religiously.
Edited to add: I only hunt public land now, and these coyotes are quite a bit spookier than the private land hunts I used to do.
