Yes, NMEA 2000 networks can share sonar data between compatible devices. The NMEA 2000 standard includes a set of messages, called PGNs (Parameter Group Numbers), that are used for transmitting sonar data between devices. For example, a sonar transducer connected to an NMEA 2000 network can transmit depth, temperature, and other sonar data to other devices on the network, such as a chartplotter or multifunction display.
By sharing sonar data, NMEA 2000 networks can provide boaters with a more complete picture of their surroundings and help them navigate safely. For example, a chartplotter connected to an NMEA 2000 network can display depth and temperature information from the sonar transducer, which can be useful for finding fish, identifying hazards, and avoiding shallow water.
