I'm just going to hunt with Constructeur and shoot what he calls in. I have a whistle, doublenasty and a Hayes that was a gift. Canada hammer and another duck call that I don't recall what it is. My more experienced friends make them sound like ducks. I make the, sound like bad New Years horns. Much to do to improve. I keep to letting them call and practicing or just a simple quack, whistle or feeding chuckle.
