I have only used the can a little and found out it stops deer in there tracks. I stopped 2 does last year. I spoke to Mike Beatty a few weeks ago ( he and I work for the same company) he shot that world record with useing a can. He said he would hit it though out the day every 20 or 30 min. Hard to say if that's the way to do it. It worked for him but so did a LOT of luck. During the peek chasing phase bucks are moveing in search of hot does all day, and they'll come in if they happen to be in a ear shot and hear it. Just watch the wind sometimes older bucks will circle around you looking for the source. Good luck
