Everything I plan on hanging, I add some sort of soft lanyard if it doesn't already have one. I make it long enough that I can put the lanyard thru the desired loop and girth hitch the item to the loop.
I do this for my range finder, rattle antlers, grunt call, can call, etc. That way, you don't have to have a bunch of different calls hanging off of you, but if you need them, they are right there in front of you with no metal to clank.
