I can't remember who make them, but they are doe estraus scent waffers. They are rubber discs that you can hang just about anywhere. Last year, my first year bow hunting, I put a couple out. Earlier in the season, before buying them, I'd been seeing several bucks, but do to my inexperience, didn't get a shot at any. Tried the waffers one day and a doe jumps the fence right were it was hanging.....I didn't have my bow in hand, nor did I have good cover so that I could get to my bow, so I just sat there and wachted her waiting for her to pass by so I could get my bow down (important lesson learned that day). Well, she hadn't gotten past a point of cover when a monster jumped the fence right behind her. Boy was he nice....anyway, he was chasing her then all the sudden stopped, turned around and went back to the fence. He stuck his nose right up against the waffer then slowly turned back around and started following that hot doe again. All this time, my bow was still hanging behind me in my stand[:@]!!! I was just too scared that if I moved to get my bow, I'd spook them off forever. Needless to say, I learned a lot from that first year bow hunting. This year they worked again. Put a couple around my tree stand, I thought it was a bit too early in the season, but said what the heck and I got my first buck and first bow kill. He came in nose to the ground....looked like he was on a mission.

Sorry, kinda long winded I guess. I pull them out when I get home and find out who makes them and post again. I get them a Wal-Mart for less then 8 bucks and they are reusable, just put them back in the container and they get their scent back.
