| 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.
