The Bradoon and Loose Ring allow for immediate release and relief from tongue and bar pressure. The bit is immediately reset to a neutral position in the horse's mouth. A horse shaking its head when bit pressure is applied or trying to put its tongue over the bit are classic signs the horse has a sensitive tongue. With this in mind the McHardy was created, it has a medium port creating space for the tongue, relieving pressure. The Buster Roller in the middle increases bar pressure and as a result extends the head and brings the nose in giving more control.
