Here in North Central WI the only call I use during the late season is a bleat can. To be more specific, only during the second rut. When I use it I only turn it over 2 maybe 3 times max, about 8-10 seconds apart.Any more than this seems to spook the deer. Also, I will only use it when I see a buck that is quite a ways away or calling blindly.
Good luck!
