The gripper is formed of 4 shells to make the compression as uniform as possible. The groundbait or packbait balls will be all of the same diameter and the same weight for accurate launching and can be used in conjunction with the Fly Ball. The Ball Maker is made of materials designed to last a lifetime.
The shells that come by default with the new Ball Maker are 60mm round. The additional shells in size 45mm round and egg-shaped 60mm x 45mm (perfect to form around leads, etc.) can be purchased separately here.
