The Gentle Guide is a great starter bit or transition bit. The unique cheeks offer similar advantages to a Full Cheek snaffle. Yet, this bit is even more gentle! The wider cheeks disperse pressure across the horses face to encourage turns and flexion instead of at a single concentrated point like the Full Cheek. The slight gag action makes this bit slower than a traditional Full Cheek because it takes the mouthpiece longer to engage. The smooth snaffle is a nice average 3/8 diameter and the copper causes the horse to salivate making for a softer more supple mouth. The Gentle Guide is easily adaptable to a German Martingale for stepping training up a notch. This is sure to be one of your new favorite bits. Copper is a soft metal, check for signs of wear before each use.
