I use them quite a bit during this time of year. Typically, once I get settled in, I will do 1-2 soft, short grunts and then repeat them about every 30-45 minutes if I am not seeing anything. I have had pretty good luck over the years with this method compared to how the guys on TV do it. I have had a few come running in, but those are rare occasions. Usually, I catch them slipping in, looking and listening for where the sound came from. That is where I learned the hard way, a long time ago, about calling too much or too often. It doesn’t take much for a buck to pinpoint you and getting busted.
