I just bought a dvd from peter Fiduccia called how to talk to deer and he explains several calls iincluding the can call, on his video he says that Do not do a full lenght slow tip of the can becuase it's a distress call, EX. lets say from start to finish you can count to 4when you do the full tip, it signifies a distress call, instead only only tip it to the count of 1 to 2 that is a hey here I am here or heyI am comming to feed with the rest of the heard. I am not tryna promote the dvd but it is deffinatly worth buying this is my secong year Bow hunting and not having anyone to teach me anyhting I have been buying every instructiuonal video I can find and this was one of the most usefull ones yet. I used the can all last year and saw nothing doing the full tip but after watching his dvd I went out last saturday and used it and called in a total of 8 deer and had a nice 6 point come in to range how ever I apparently bumped my bow somewhere going in that morning because I missed at 12 yards and after going home and shooting again I was off a foot!!!! so I resighted and am going back tommorow but that surly worked this year where as again using a full tip last year I never saw anything. also only tip 1-2X in a 20-30min period any more will alert the deer. good luck
