Do I need to use a paddle wheel speed transducer with my SmartCraft speed gauge?
You do not need to use a paddle wheel speed transducer with the SmartCraft system. Boat speed is also available from the on-engine Pitot (pressure) speed sensor, and is available if a GPS is connected to the system. However, the troll control function of the SmartCraft speed instrument requires the input of the paddle wheel transducer for very low speed accuracy.
