Thanks for the advice R.J. Your right as I would'nt want to call by mouth for any length of time, espesialy on coyotes.As fox tend to in my experiance come running in right away.I checked out hofts foxpro on the swap & shop forum.Wow a lot of diferent calls ,sounds great. Since I have never gone out primarily for varmits I'm going to try the jack rabbit in distress call I just purchased.I see the occasional coyote but not like when I lived and hunted in Alberta.Thanks again.
