I have a True Talker tube, and the fawn call does work well on does, it seems. Not just in the rut either.
During rut, I only grunt and rattle. I used to think rattling was a waste of time, till one day I was close enough to a fight, and could even make it out thru the brush. The larger of the 3 bucks (that I could see) was really giving another one of them a hard time. I thought that would have been a good time to to try and sneak in and get a shot, but I figured I'd make too much noise in the tree.
But the Sound-the sound of those antlers as two hit each other was astounding!
LOUD! and so this all plays out, I didn't get a single shot at any of them-but that was one of those "teach me to fish, and I eat for a lifetime" moments. You see, when I first heard it, shortly after, I had heard something going thru the brush, and not quietly or cautiously, but "all out". After seeing all this and pondering over what had happened later that night I realized-the two had started, and what I had heard was ole #3 had come in-cause he had heard the combat. I was about 50 yds away, but in the woods that sound carried forever, I can only imagine the concussion being generated there. so now when I grunt, I follow that a few minutes later with HARD rattling. Works pretty good.
