It's obvious that in this game that you know a contact's depth but were/are subs actually able to determine the depth of a submarine contact? I only ask because I've played dangerous waters and sub command a LOT (both of which seem to set the standard for realism in a subsim) and there was no concrete way to determine a sub contact's depth....Unless I made a glaring oversight this whole time

It was more of a calculated guessing game.
Thoughts anyone?
