Peto, thanks for your help and suggestions. The point of the matter is that I have tried many different angles of approach and depths ranging from PD down to 200 ft without ever having exposed the periscope. This last time I know it was the destroyer out in front who detected me. The other couple of times I came in from the points and am not sure whether one of the flanking DD picked me up or the DD out in front. I've played SH1 for the last ten years as a member of the PTC and have played SH2 and SH3 so I really don't consider myself a novice when it comes to playing SHIV. But since I've tried playing SHIV with the 1.3 I'm really feeling out of my depth. I tried every approach I can think of and I still get detected, it's getting really fustrating.
