 Our hydrophones are a powerful tool for figuring out where we are in the water. Using 4 hydrophones,​ we can calculated our bearing to the pinger. For details, see [[cs:​hydrophones:​pinger_bearing:​start|Pinger Bearing]]. Our hydrophones are a powerful tool for figuring out where we are in the water.
