I used Dan's bugle for more than 10 years, and harvested over a dozen bulls with it's aid. the only issue that i saw with it, that didn't bother me, is the degree of dedication that it takes to master the call. Once you have mastered it, you will enjoy the results, if you can handle calling every hunter in on the mountain that is.On a bit of a side note, it takes a pile of wind to operate the call correctly.
