bullcan,welcome to the board.I have the t-rex call and its a pretty coarse sounding call.I picked it up from all predator calls.I have not called in a bear or cougar with it.But like they say,right time and right place.I have called a bear in with all predator calls j-13 javalina call.Real good sounding call.I also used lance hommans predatr call to call in a cougar.He sells his calls right here on the board.Along with a lot of other great call makers.If you do your scouting right and put yourself in a good area with lots of sign,I dont see why you won't be able to call one in.Just have someone to watch your backside.Its a little different using a hand call than a e-caller.Good luck and let us know how you do.take care,daveyboy /ubbthreads/images/graemlins/smile.gif
