Curious as to what you all are using for grunt tubes. I am interested in something for the woods of PA, I don't want a tube that grunts so deep it scares the smaller guys out of town! I am looking for a tube that is adjustable to be able to call younger bucks in for my kids but still have the option to go deeper when I am in the woods. Any thoughts would be appreciated. The last tube I had was so old all the markings as to who made it wore off.
