Primos Mini Sonic Dome Diaphragm Elk Calls - You have to try a Mini Sonic Dome. This is not simply a call for youth or people who perceive they have a small mouth. People, who have been calling with regular size mouth calls for years, will be blown away by the elk sounds they can produce with the Mini Sonic Domes. Having a call that fits the roof of your mouth will make all the difference in your calling ability. The Mini Sonic Domes have been designed so the call is automatically positioned correctly in your mouth with a consistent distance between the reed and the roof of the dome. All this makes it incredibly easy to consistently produce true elk talk. Latex Reeds Mini Frame
