I'm new to elk hunting and trying to figure out how to blow mouth (diaphram) calls. I bought the Primos sonic dome call pack. Its got the white, blue and red ones. They truely sound like crap when I blow them. I'm obviously not doing something right with my tongue, or its not positioned correctly in my mouth. I'd really like to get better at this but just not sure if I'm even on the right track. Any tips guys? Also maybe there are better/easier calls out there to get started with, so I'd love to hear what other brands everyone likes. Thanks
