Used it every night, it is as advertised. The battery life is good, lasted 3 hours on a single battery(you get two)on high. Used a C clamp to attach to shooting house(taped the light to C clamp) and left it on once it was dark. I had a great view thru scope for over 250 yards, the green light did not bother pigs.

I'm sure it will work on Coyotes here also.
