diaphram call raspy old hen....best call i have ever had....99% success with this one (would be 100 but brother missed with his bow at 18 yards.....he will never hear the end of this one).....don't know why, but the turkeys i have hunted in this area like that call.....each state, or location will be different...i do think that if you find a place that really likes one particular call....use it!!!
