It depends on the time of year, I've used the Can right before and at the beggining of the rut and had lots of sucess. It also depends on the deer, Ive messed around w/ calls while deer are rightaround me during all seasons, and they've never reacted. Sometimes the deer just dont want anything to do w/ you. Never had much luck rattling, so i cant help w/ that. I always carry a Can and a grunt call into the woods w/ me. I also tend to "over call" so i set time limits on myself so i dont call every 20 min. i try to space it out at least an hour or so. Thats just my calling strategy. Honestly I count more on putting myself where the deer move than using calls.
