Tong view (located in the boom) is beneficial to operators when grabbing a bunch or drag, maximizing grapple usage and operator efficiency. Cameras can be viewed on both the PDU and the secondary display unit (SDU). Each display can toggle between the blade view camera and the tong view camera to accommodate operator preferences.
