Zilco Neck Stretcher
A simple, yet effective training aid used to encourage horses to stretch into contact with the bit. It works by placing gentle pressure on the poll when the horse raises it's head, and gives when contact is achieved.
The single length of elastic is passed over the poll and through the bit rings. It is then either passed through the horse's legs and attached to the girth, OR on either side of the horse to the saddle or lunge roller (as pictured here).
