Sprenger Max Control (Danger) Bit Double Jointed
Sprenger's Max Control ("Danger") Bit is popular because of the way it encourages the horse to soften.
When the horse is soft in the rein, the bit works like other double-jointed loose ring snaffle bits. But if the horse resists against the hand, the mouthpiece locks to act like a stronger straight bar bit until the horse relaxes and works properly again.
