I have hunted turkeys out of my stands several times and have always been succesfull. Dont expect to go into a stand the first year and turkey hunt out of it and expect to bag a bird. Doesnt work that way. It took me a few years to study their behavior and knowing exactly thr right time to draw on a turkey from above. My advice to you as well as make sure someone else is with you. Put them on the ground and have them do the calling. When was the last time you saw turkeys mate in a tree? Also if you plan on hunting turkeys from a stand USE YOUR DECOYS! this will draw attention away from you and more on the fakes.

Remember that 270degree vision they have? That works for up as well, and turkeys do have predators from above,eagles owls etc. from when they were poults. They'll bust you in a tree drawing a bow for sure! You're better off in a ground blind!
