Reduce Risk of Collision with Lowrance
Using Automatic Identification System (AIS), Lowrance's transponders automatically broadcasts a vessel's identification, position, course and speed and receives surrounding vessels' info to prevent collisions in congested shipping lanes and ports. Both the compact NAIS-500 and NAIS-400 draw minimal power and network with HDS Series fishfinders and chartplotter combo units as well as Lowrance VHF radios.
