The Pacifica wheel has proven to be an excellent choice. It has a large, solid work space & an easy-to-use splash pan. The Pacifica employs a system of 4 polyurethane belts and a large electronic capacitor which makes it extremely quiet. These wheels have been built to last with a 13" aluminum wheel head and the perfectly smooth foot pedal. The GT 400 develops 1/2 hp so it can handle 50 lbs. of clay. The GT 800 develops 1 hp so it can handle 100 lbs. of clay. Both wheels carry a 2-year warranty.
