Since those gobblers are heading away from you something is attracting them, you need to find a way to be more attractive. If your one deke is a hen put her out in the open where she'll be seen and you'll have a clear shot, then call to the gobblers with sweet yelps, purrs, and clucks. If it's a male deke save up for a hen and place them together as Rocky described, gobblers hate another guy hogging their girl.
