Even the best turkey callers will find that their yelps and clucks just won't bring that Tom in. Some will even hear the gobbling moving away from their set-up.

Those hunters may want to try a different tactic - pursuing the turkey. Hard-to-get gobblers will gobble in response to calls but may not want to come to the call. That turkey may be enticed, but he is already with a flock of hens.

In this situation a hunter can circle around the turkey, attempting to get in front of him. If there is a field or area where you think that gobbler is going, "Head him off at the pass." Hunters will have to use a ridge or other terrain features to hide movement and quickly get set up in the new spot.
This is a case where pre-season scouting is so important. Hunters have to know the land they are hunting on and where the "hot spots" for turkeys are.

If you are hunting with a partner, you may want to trick the turkey. The shooter moves towards the turkey's position while the caller moves in the opposite direction. When the gobbler hears the volume of the hen calls becoming lighter he will think the hen has lost interest and is walking away. He may move closer, while still keeping a distance, and walk right into the shooter's sight.
