When I bow hunt or rifle hunt, I use a true-talker grunt tube...works awesome! I have had several deer come running across open fields to within shooting range. I accidentily spooked a deer one time and the deer took off running into this open wheat field for about 150 yards. I gave a soft grunt and the deer stopped...looked back my direction...and I gave one more really soft grunt...and the same deer came back to within 30 yards of me.

Make sure you are calling very softly. The deer will be able to hear it. If you are grunting "blindly" (you don't know if a deer is around or not), then make sure you don't grunt too much. I only grunt once every thirty minutes or so. Also try different pitches. I have found that medium range tones work best for me and where I hunt. I don't have a lot of "record" bucks where I hunt. If you use a really deep grunt, then you may cause a smaller buck to become intimidated, leaving the area because a more mature "buck" is in the area. The HS True Talker grunt tube is great because you can make all sorts of different tone pitched grunts.

As far as the can goes...I haven't got much experince with it. I have one, but I seem to stick with my grunt tube because that is what has worked great in the past. Why change what has been working.
