For a few bucks I think it would be well worth it to pick up elknut's playbook and dvd package. Wouldn't hurt to pickup a call package as well.

Some of the information is pretty basic, and the production quality on the DVDs is lacking a little bit, but for a first time elk hunter it would be money well spent.

I use the lil chuckler bugle and cow call with a mouth reed and after a little practice you can do pretty well with it. A lot more versitility than a hand call and you can keep it in your mouth at the ready and your hands free.

Good luck, you'll be addicted.
