Calling Elk can be either easy as can be or frustrating enough to make you want to choke whoever is within reach. Using a diaphragm call for SOME people is hard to learn. Elk vocalizations are fairly simple to emulate but getting that diaphragm just right in your mouth and getting the vocals just right without the "squeeks" takes a good bit of practice. That DVD would probably help you a good bit. Good sound on your TV so you can "match up" will help. Knowing when to "shut up" is one of the most important things I have found in both Elk and Turkey calling. Too many people out there tend to go bat crap crazy over calling and "educating" Bulls and Toms enough to make them 100% shut down.
