The DS60 gives required information for berthing and docking of vessels 50,000 GT and greater, such as container vessels and tankers. Information relayed includes speed relativwe to ground and water for fore-aft and port-starboard directions. Operation at dead slow speed enables precise docking and safe navigation of massive vessles in demanding circumstances such as narrow channels or straits. Operation at high speed enables more economical cruising. 
	The DS60 maintains the measurement acccuracy of the DS30 but is more compact and therefore requires less space and time to install. Three display modes are available on the 8.4-inch color LCD display: 30axis speed, berthing, and NAV data. Information is shown in alphanumerics and graphics. An optional remote control may be purchased to remotely switch modes. An IP56 waterboof box may be purchased for the display. 
	A DS661 gate valve and tank is standard with the DS60. The DS661 may be replaced with the DS660 tank without flange.
