Correction bits are training bits used by advanced riders and finished horses. The mouthpiece applies pressure to the horse's tongue at the flexible joints of the port and the bars of the horse's mouth. Correction mouthpieces are used on shank bits, gag bits or combination bits. There are multiple styles to choose from that includes copper, sweet iron, or stainless steel. Correction bit shank styles can be plain, have an antique brown finish, or silver overlay trim for a show bit. Use correction bits with care. They are often used in reining shows and other competitions that require a finished horse and soft handed rider.
