RE: deer calls
i use the primos grunt call but it will freeze easy in cold weather. I use the true talker when the primos freezes up. The true talker doesnt seem to freeze as easy plus it is rubber coated so if you knock it against your gun it doesnt make much noise. I use the primos when it isnt froze because i like the sound it produces better. But if i was gonna get just one grunt call it would be the True Talker.
