I am interested in getting the Walker's game ear or one of the other brands of power muffs. They would be great for dove, ringneck, grouse or whatever else. I have a six year old getting ready to hunt soon, and don't want him to end up with the same ringing ears as me. My question is - Has anyone tried these to listen for gobbles? Wondering if you can get a good sense of direction with them on. Thanks.
