10 Ring Training Attachment
This is a really useful training aid. It is a cross between a German martingale and running martingale, but allows for more choices. The 10 ring attachment is worn like a typical breastplate or martingale, but allows for multiple places to run the reins through for differing amounts of leverage. I can be very useful to help "explain" what you are wanting from your horse. When used with care, it can be a kind guide to help the horse understand.
