Yep, I took mine a couple times and agree with those on another thread that it's way too easy for the sound to become "ducky"... I had my trusty True Talker with me tonight, and I think I can make the call pretty well just by closing my hand over the end, opening it up, and then cupping it closed again.

The regular grunt on the Growl call is good, but when trying to add much volume, it's too easy to have a mallard come in for a landing.
