The Drake "whistle" took quite a bit of practice! I would describe it like a "peep" whistle.. for me it took very tight lips almost closed off. With a pretty substantial burst of air pressure. At first I assumed it had a lot to do with the way I close it off at the end. It is important to have that right closure but more so the burst of air you give and the abrupt tight force of pressure. At least for me. A heavy exhale push or " punch" from the diaphragm
Need a part two ol son! I’ve seen it all work in the field. Ain’t no one I know but in the hours to learn it all but Escambian Outdoors did it for ya! We put it to the test in a few days. Good stuff
