I started using an extinguisher about 3-4 yrs ago, haven’t found anything else that I like.
I used the buck grown when it came out with success ( not the growl, just used for grunting) and then switched around but now am using the extinguisher and its called some bucks up this weekend...I've had success with all of them, but I use them only during the rut and call every 15/20 min...I use the dominant buck grunt and don't care about running off small bucks though I have called up my share of em!
