I agree with Ron too, it isn't just a dominant buck sound, its a frustrated buck sound.
IMO, for any calling to work well enough to get a deer into bow range, the deer has to be able to hear it, but not see where it's coming from, or, there has to be real deer around or a decoy present to confirm what he heard. I rarely use a decoy due to my lazy nature. However I've had great success calling in critters (deer, turkey, elk and more than a few coyotes), by setting up where the animal will be in range before it can see the location I'm calling from. They hear the sounds, think there is a buddy of their own kind there and come in. If they can see the area and don't see their buddy, they aren't coming most of the time.
