gobbler calls

Do any of you use the ones that you shake and it makes a gobble. If you do how do you like them and when is your favorite time to use them.

Had a call maker on the radio this past Mon talking calls. They use this call as a last resort to make a gobbler think a jake is breeding the hen, but they don't like it that well because of the danger aspect. In highschool I had a friend shot in the face and lost his eye turkey hunting. He was the type who's face gets reddish outside and the guy he was hunting with saw this through his facemask and shot him. 2 seasons ago a guy down the street from my brothers house was mistaken by his buddy and shot. It would take one idiot to hear your gobble and he's jumping fences hunting you. The woods are crawling with morons and over excitable hunters, so watch your back at all times especially using a gobbler call.
