There are much cheaper alternatives to the name brand " Walkers Game Ear" that work almost as well or better than the Walker' s. Take a look in the Cabela' s Fall master catalog. There is another one in there, i forget the name, but it works just as well. My father-in-law has both the el-cheapo and the Walkers. He swears by the el-cheapo! I' ve also used both and can tell no difference.

Just keep your options open.
