RE: Brand New Hunter
Deer calls will work, but they are not the end-all, be-all of deer hunting.
For turkeys, an arsenal of calls is a must, but deer don't quite respond as well.
During the rut, a grunt call is sometimes effecting at getting a buck's attention. Does will sometimes respond to bleats. In sum, scent is probably a bigger key to success in deer hunting.
Deer live in a world of scent, and their olfactory (a sixth, chemical analyzing sense - similar to smell) and their sense of smell make them very very sensitive to different odors and chemicals.
Read and learn about which scents to use and why, learn how to cover your own scent, and you'll be on the fast track to success.
