Thanks LukeFF, very helpful.
Guess I got lucky, my first shot, I forgot to switch the detonator to contact, but set the depth to 5 feet...watched her run right underneath a small split freighter and absolutely decimate her. Although I ran out of fuel,(

) guess I have to learn to dive during the day and not run surface till I find contacts...
Also, I do run PE3, and it seemed like the special effects (Oil Slick, floating boxes, the oil burning after it she sinks, and my fav. dead bodies!) were missing. I know it doesn't necessarily support RFB but it was listed in the install order on the main page..Any Ideas anyone?? Experienced somthing similar before with TMo and had to reinstall, but I'm trying to avoid that if at all possible.
Again, thanks for the fast reply and keep up the hard work!
