I have 2 questions that I always wondered about:

1. Does the depth a dc explodes at play a role on the explosion radius and damage? The denser water could mean two things:


-Smaller radius due to more energy needed

otoh:

denser material is better for transmitting vibrations (explosions)

So which one is true?

2. what has more detection range: The small radar subs carried or the huge passive radar detector? And why?

Logically the passive detector should be better in range, but in SH4 this seems to be not true. Or is it handicapped by the next-to-useless japanese radars with their little range?

Any info on that?
