I prefer the knightn hale small can young doe in estrous call,I live in minneapolis and in the metro area there are several spots that hold alot of deer that cause car accidents so they have what is known as a sniper liscense.if you can pass the snipers test with a bow and have a good record you can shoot unlimited does but still only tag one buck(stupid rule) I watch does at a feeder in someones yard and turn my can over and they immediately perk up and walk to me.It is supposed to be for bucks durring the rut but works for both.I would recomend the small can to lure every size and sex of deer
