The MB 04 is similar to the MB 02 in that it will rotate on the tongue and apply tongue pressure, however, it has a small (¼") port that introduces some tongue relief to the horse. The port allows the horse to swallow and move his tongue when he is moving forward and relaxed, which acts as a release or reward. The mouthpiece is curved, and it wraps around the bars and lips instead of pinching.
Notes: The MB 04 provides an excellent transition from Level One to Level Two. It is suitable for a wide range of horses including green horses, experienced horses entering the Myler System, horses that have been ridden exclusively in a single-jointed mouthpiece, or horses that have not been ridden for a while needing re-schooling.
The dee without hooks is a traditional "D" shaped cheek with fixed attachment of the mouthpiece. This style keeps the mouthpiece from draping on the tongue, providing a more direct signal than the loose ring. The straight side of the dee will not pull through the mouth and does not pinch.
Size: 3 ¾" dee ring on 5" and 5 1/2" mouthpiece, 3" dee ring on pony sizes 4 1/4", 4 1/2", 4 3/4"
Discipline: Mainly English
