Being a real novice I struggle with staying undetected - unsuccessfully. They always know excactly where to find me. So I'm pretty much in need of tips on how to stay undetected while approaching a convoy or having a "dogfight" with an enemy escort. Obviously in order to get in touch with it I can't move like a snail unless I'm lucky with their course abling me to intercept it.
Most often I end up in a situation where I and a destroyer (or more) have visual contact, but going under and changing course doesn't seem to do much.
I do obvious things like keeping the periscope down, not using sonar, and keeping low speed (1/3) at most. Anything else?
All hints and tips are appreciated
