I have had two different scopes from them and I was not impressed. Two different rifles and I could not get either scope to zero in. This was a fews years apart so maybe I just got a few bad apples. I saved up and bought some Burris optics( office in my home town) and have not looked back since.
When calling coyotes, more often than not they will circle on a target they are
coming into and approach from the downwind side. Presumably they do this in
order to align what they smell, with what they are hearing.
This means that you should always have your downwind side camouflaged and have
an open shooting lane. If the area is heavily covered the coyote could come in
take a look and be gone, with you none the wiser.
