Three diaphragms in a little primos case. Been using phelps calls though. And a bugle tube. I have a really bad habit of putting them in my lap when i sit down then standing up and never seeing them again, or eating dirt.
3 matriarch cow calls by Rocky Mountain...one around my neck, one in my pocket, one in my pack. Early season they are deadly. I find that thru the first two weeks of the September archery season, the bulls here in Idaho rarely respond to a bugle. From about mid-September on, I add in the Primos terminator with the silicone snap-on reeds. That's all I ever need. The less calling I do, the better.
