RE: those primos flip cans
just like any other call out there, there's a right time and place when to use them. I've used them a little, as with grunt tubes, and rattle sticks. Sometimes they work, sometimes they don't. If your hunting an open field, I think their less effective, because the deer are looking for a visual. In thick timber, they may work a little better due to they can't see as well, but, thats just my opionion. Experts on here probably will have a completely differant view.
