sonar technician

A sonar technician is a specialist who uses sound waves to detect, identify, and track objects underwater, such as ships, submarines, or underwater terrain. They operate sonar equipment—similar to underwater radar—that emits sound pulses and listens for echoes to create images or maps of what’s beneath the surface. Their work is crucial for navigation, submarine detection, and underwater research. Sonar technicians require a good understanding of acoustics, electronics, and maritime operations to interpret data accurately and ensure underwater safety and security.
