Hey BT, it also requires and electronic caller too, right? Or are regular crow calls sufficient?
Personally, I use an electronic caller but I've seen some guys who were pretty good with a mouth blown call. If you go that way, get a good training tape and practice a bit before you go out. Crows are among the smartest critters you will ever hunt.
If you're married, practice in your garage or while driving your car rather than at home to avoid serious injury
