I think it works well in pre season when the fawns are still young.But as the season rolls in they dont come to it as well and a lot of times they will turn tail and run off.So it is a marginal at best call to use only at the beginning of the season.If you have a lot of does bread the year before suring the secondary rut then you might have a chance.I also agree it sometimes isnt the best call to use while hunting.They do come in fast and on high alert.Hard to get a good shot off then.
