The NS Tranz Hunter-D is excellent for directional control and exceptionally good for tight turns during faster work as the mouthpiece should not slide across the mouth. It is also safer for young horses as it should not pull through the mouth in a panic situation. The NS Tranz Hunter-D is beneficial for children or novice riders who may not be sufficiently experienced in supporting their inside rein. Good for dressage as it gives the rider greater shoulder control on a circle and helps set up the bend when changing the rein or with lateral work. The stability the NS Tranz Hunter-D offers is often useful for horses that are overactive in the mouth in a loose ring design.
