A fixed 10x would not be my first choice, but it could work. I call coyotes a lot in very open country. Most of the time I have my variable scope set at 8-10x when I start a call. I can almost always see coyotes approaching from 100 plus yards and can “get on them” at a distance, and kill them as soon as they stop or slow down.
I’d not use a fixed 10x in tight cover.
