I have found that my old MAD Calls "Thunderdome"aluminum slat call reallys drives these birds crazy. I have been very successful with the call even though I don't think it's the best sounding. My friends all bought the Illuminator by MAD prior to last season and everyone killed a mature gobbler on a WMA at that. We accounted for 9 of 18 birds taken with a possible 50 hunter hunting. While I may not think it sounds great, it sure has worked! What have you found to be your favorite Osceola call?
