I very seldom use the can or a call.I do however rattle and have had great success with them.I took a real nice 144 lb.9pt. opening morning this year. a six pt durning B/P season. all total this year I have rattled in a total of 7 bucks for me and my wife.last year I rattled in 5 bucks that we took (4 more we didn't take)for the two of us.

rattleing works real well for me in Central Fla.this year they came to the horns all the way through the season.up until two weeks ago.
