Hydrophones give you distance as well as bearing?

Take another bearing and advance your old bearing to this new (fake) position. this will give you a fix on the target.

Oh, how I wish I understood this.

1. "You draw the bearing of your first sound contact and mark your position".

Got it.

2. "Wait 3 or 6 minutes and advance your position at the estimated speed of the sound contact."

So the three or six minutes - is this related to the 3 min 14 sec rule?

When I "advance my position" is this in any direction, or on the original target bearing?

Got the speed - that's from "slow, medium, fast" from the hydrophone operator and using the standard speed ranges for those terms.

3. Take another bearing and advance your old bearing to this new (fake) position. this will give you a fix on the target.

Nope. Your brilliance met a brick known as my forehead on this.

Brag/Dantenoc - I know I'm the Gilligan and you two are the Professor in this little play, and I really do appreciate your help. Don't give up!

Dantenoc is an absolute genius. I always learn a ton when I read his posts...

Rykaird - do not despair, i did not "get" it either.

But this page explains it for dummies like us
