[quote="mike_espo"]I am starting to see a pattern....It seems escorts first run in, with Active sonar pinging away, attack vigorously, then they just listen.
Then after 30-45 minutes or so, they lose contact, do not try to regain contact by using Active sonar, and leave....
I usually dive to 180m. Never hear pinging again. Scenario is in summer 1943
Maybe you're hiding under a warm/cold (Thermal Layer) of water and don't realise it? -Nightowl
