I really believe the Deer Flute and True Talker are peers with out company from my testing.
Like Rob was, I've been a faithful True Talker carrier for years, and it's worked extremely well for me. Then earlier this year, Rob sent me a Deer Flute to try. I made mention of it in another post recently, but I've got a strip of woods separating the 17th green and my back yard, and evidently there was a momma doe bleating to her newborn in it a few days ago; she wasn't too far away, but the woods are too greened up to see her. I ran in and grabbed my Deer Flute and matched her bleating
perfectly.
The Deer Flute will definitely be accompanying me to the woods this fall.
---Poor lanyard set up. Just some rope ran througha very thin rubber sleeve.
This was my big complaint, too. I've got two of them (my three-year-old confiscated my first one

) and on both of them the lanyard tore through that thin strip of rubber. There needs to be a better way to secure it.
