The Turtle Tactio with Flex is specifically engineered to accommodate the larger or sensitive tongue. This combination of Baucher cheek and Turtle Tactio mouthpiece usually helps the rider to achieve and maintain a rounder and more correct outline. If your horse is constantly resisting, strung out or coming above the bit the usual response to the Turtle Tactio Baucher is a head lowering action and softer feel through the rein. This design often proves beneficial for the over sensitive mouth. Highly recommended where help is needed for straightness and bend.
