Martin String MartingaleThere are many different types of martingales available with many different names. The basic purpose is to assist the rider in achieving a submissive horse and appropriate head and neck carriage. The martingale should only be used with a ring snaffle since it exerts a large amount of leverage in addition to the regular bit/rein combination. The martingale goes around the horse?s neck just in front of the shoulders and attaches between the front legs to the center cinch D-ring. The reins go through the martingale rings and when the reins are adjusted properly, the rings apply additional pressure when the horse resists a cue. The horse achieves a release of pressure when it gives to the cue and regains proper head carriage as long as the martingale is adjusted properly. To adjust the martingale, before placing the reins through the rings, take each side by the ring and it should be long enough to pull straight up and reach halfway up the horse?s neck. This length allows the horse to move freely when it is traveling properly. Since the majority of martingales have no fixed end point, the rider can easily overflex a horse. Be sure not to adjust each side too short. Also, be careful not to let the martingale rings slide too far forward on the reins and get caught on the bit ring.
