Just this past season I experienced a hunt where I had to grunt in a 7 year old buck. At 80 yards, he stands over a scrape directly downwind. I knew the direction this buck would most likely take after he freshened the scrape and it wasn’t towards me. So, testing the Ozonic unit was my only option. I let out several short grunts and got his attention, as he started walking off I hit him again and it peaked his interest. He turned, checked wind and came in on a string… DIRECTLY DOWNWIND!! This shouldn’t happen!
