RE: New Deer Call
I'm a little skeptical. Every year they all come out with something new just in time for deer season. You've got to know that aBIG part of it is just trying to find another way to get hunters to let loose of some of their money.
Having said that, however, I know that the sounds from some of these really do attract deer - bring them into shooting range, etc.
Long before anybody manufactured these things, people were using their mouths to imitate some of these noises with great results.
I guess if you can spare the money, it probably won't hurt to try.
