Level: Two, Three
Design: Curved mouthpiece with two hinges and upward-curved piece in the center. Port measures 1 1/2"
Function:Downward pressure on tongue and bars. Collapses on outside of bars.
Usage: Rewards the horse with a "comfort zone" when relaxed at the poll. Good bit for collection and stopping. Works well for spoiled horses and horses who run through the bit. A good choice for horses with low palates.
Design: A Dee ring with a short straight purchase at the top of the Dee. The headstall is affixed to the purchase and the rein is then attached to the Dee. The rein has a fixed attachment to one or two hooks.
Function: Functions as both a direct action and leverage bit using a curb strap or chain. If the rien is attached to the top hook, it works as a direct action bit, exerting the same amount of pressure on the mouth as on the reins. If the rein is attached to the bottom hook, it works like a leverage bit, tilting the mouthpiece forward and applying pressure to the parts of the mouth curb and poll.
Usage: Used in English disciplines.
