Who has used them and what is you're opinion on them?
|The Irish martingale is not a true martingale in the sense of a device that affects the rider's control over the horse. Thus, it is sometimes known as a semi-martingale. It is a simple short strap with a ring on either end. The reins are each run through a ring on either side before being buckled. The Irish martingale's purpose is not to control the head, but to prevent the reins from coming over the horse's head, risking entanglement, should a rider fall. It is used mostly in European horse racing.|
