-Our hydrophones are a powerful tool for figuring out where we are in the water. ​Look at the subpages for the maths involved.+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]].

 +==== Testing Procedure ==== 
 +==Materials:​== 
 + * 1 tub of water 
 + * 1 pinger 
 + * Hydrophone Test Rig 
 + 
 +==Test Rig:== 
 + * Pinger at one end of tub 
 + * Hydrophones at other end of tub 
 + * If lots of noise in readings observed, can place towels around tub
