In a WWII uboat ?

I suddenly feel stupid to have spent several hours learning how to use the passive sonar with the ruler in Dangerous waters...

well not "accurate" I suppose the hydrophone range is not far enough to allow for enough time between readings for sufficient accuracy. Especially if the contact is moving fast... or heaven forbid, changes course!

But it looks like you should be able to get somewhat close. if you sit still for a hour or more. Just hope that by the time you get your final reading the contact isn't already 16km away and moving away!!!!

"I got it Captain!! I got it!!"

"got what you Hydrophone weenie?"

"the contacts exact location, heading and speed!!!"

"and?..."

"it's bearing 165, range 17km, speed 19 knots, heading 180 (moving away)... we can NEVER catch it!!!"

"errrr... great job.. thanks"
