Thanks for the link, was heading to bed but think I'll start next patrol so can see how this works.
Also, I figured out that it was my tactic that was keeping them from finding me.Next time, the escorts were tough because they found me and stayed with me even when I was at 600 feet, caused hull damage to go to 1 from a very close charge, many others that shook the boat but none that did damage.Stayed with me for over an hour.
Side note, wonder if could make it where depth charges could not be set to explode below a certain depth as per history for IJN.Something like this silently slipped into a mod could be fun, players wouldnt know either way unless they found out.Then again, it would take away from the danger if can just go deep to avoid them.
