Well, they just killed me or I killed myself. Funny, one was always listening pointed right at me, this one listening as the other terd makes a pass.
Then the listener makes his run. I had a mild bow dive. Subs always hard to control over 600ft deep, but I went to near 700 a few times and reversed to get back up. This time I started reversing at 600 ft, but couldn't pull out, started blowing tanks at about 650. By the time it stopped I was past the mark and sub blew somewhere right past the 700ft mark. Not sure if that's the line, but somewhere around 730ft the massive damage took place.
