Are Japanese destoyers too good at detecting your sub??

The key to remember is they may not actually be detecting you when pinging. They're pinging away trying to detect you. You've been made when the pings suddenly start occuring closer and closer together. In that case, you may want to have a listen at the sonar station yourself and see if it sounds like he's increased speed and is closing (or press "Report nearest sound contact"). If he's increasing speed and closing, it's time to go deep.

Try to hold off your turn until after you're under the thermal layer (if there is one) then lay over hard to port or starboard (I try to turn towards the convoy) and rig for silent running. Of course, if you hear him pass right over your sub, it's time to turn regardless of depth. Take advantage of the fact he can't hear immediately in front of him, directly below him, or at any range in his baffles and lay over towards the convoy and make max speed. Once you hear the detonations, rudder amidships and silent running, continuing the dive if you haven't passed a thermal yet.

Verify your bearing relative to the convoy (using the sonar contact lines) and you may still get a shot with the stern tubes once you've passed under them (or even come up in the middle and get them with forward and aft tubes).
