Jump'In Waterford bitComposition: German Silver (65% copper, 23% zinc, 12% nickel) is a relaxing and solid alloy. Effect: the large flat rings offer a better direction and a light lever action. The Waterford cannons split the contact points. Tips: for horses that are used to taking too much contact, this bit makes them lighter on the hand. Maintenance advice: rinse the bit after each use to prevent any residue deposit and to prevent your horse from feeling any discomfort.
