Sprayed it on the speaker? I don't put any of that stuff directly on me. I practice scent control with washing my camo with odor killers, dry with fresh earth dryer sheets and bag in a clean, clear, plastic bag until the hunt. I use cover scents spritzed around the decoy and caller, but not on it. A shot or two directly downwind, then I retreat to the crosswind side of the decoy/caller. I just wouldn't care for me or my gear to smell like rabbit innards. Not if I want to sleep INSIDE the house!
