I have the same problem and have used the Bugling Bull external for the last 7 or 8 years, it is a great call and elk seem to really like it. I have hunted with other hunter and let them blow their Primos etc with no answer, and then get an answer with my call at least a dozen times. As stated you can't do everything but I get enough out of my call to bring them in.
