The Loose Ring allows for immediate release and relief from tongue and bar pressure. The bit is immediately reset to a neutral position in the horse's mouth.
The Ported Barrel was created to relieve pressure on the tongue via the the medium port, which creates space for the tongue. The Barrel joint relieves pressure on the bars by spreading it over a larger area and limiting the nut cracker action of a conventional snaffle.
HBE suggest, best suited for: Horse that travels behind the vertical and may also demonstrate signs of tongue pressure (see below image for examples). Great for turning as has independent side movement
