RE: the can
I use the "Original Primos Bleat Can"
I usually wait til I see deer before I use it, but I occasionally will call 2 to 3 times with short pauses inbetween, then I'll rattle a hard sequence and repeat after the next 30 minutes. This works best before the peak of the rut here in Ohio, otherwise the bucks will hear it, but then stay with the doe they have and not even think twice of the sound he just heard.
