The FES Copper Correction Bit is an attractive, lightweight bit designed for intermediate to advanced level horses. It effectively provides a 'comfortable zone' to reward horses when the poll is flexed, promoting better behavior and performance. Each side of the bit can be worked separately, applying tongue pressure at the joint for precise control. The copper overlay mouthpiece promotes salivation, increasing your horse's responsiveness. This bit enhances sensitivity, enabling better communication between you and your horse. The bit has a mouthpiece of 5", cheeks of 6 3/4", a port of 2", and a bit diameter of 7/16". It is from the trusted brand, Schneiders® FES.
