4 northstar ns3100 multi the ns3100 multi measures and displays speed, water depth and water temperature. It can calculate and display average speed, maximum speed, trim speed, trip log (distance) and total log. An installed ns3100 multi usually has two parts: the display unit. Depth and speed / tem...
