Pythos indicated that SH4 models active sonar incorrectly - that its always "on". Actually this is a correct setting for the Imperial Navy - they more often than not were constantly pinging - the thought being that the pinging would run off or find an attacking sub. Historically - many convoys were found and tracked BECAUSE the active sonar could be heard father away than the merchant screws could be. This is one reason you may be getting "caught". If your in the cone - your going to get found. Its also why diving deep and being a hole in the water is a good tactic - depth often equals a layer in SH4 - which helps tremendously in shielding you from sonar.

It should be noted that standard Allied doctrine was to use active sonar ONLY when searching for or attacking a target - so Pythos was not "wrong". Different navies used different doctrines.

Now - I am going to likely catch it here for this "tactic" - but I often turn broadside to a convoy from one side or the other of the base course - then fire a shell at the lead escort - as soon as he "spots" me - turn end on and hit the gas - end on he will often lose sight of you (especially at night) and then you head back at a 90 angle and intercept the convoy. Sure they are zigzagging - but if you time it right - you can get in close and get off a few shots while the escorts pour on the coal just to get back to the sheep they left partially unguarded. Note - you wont pull all the escorts off doing this (unless its really lightly guarded) - but with the increase in "loiter/search" time - you have a shot of opening up a seam inthe screen that you can penetrate or exploit. Getting IN is the hard part - once your shots are away its dive deep and go slow and pray.
