Haha, you're hardcore man sir
To search contacts at patrols, i am using this script: search -> search on patrol-> no station hydrophone check for real nav
It has best behavior for me.
You just point your heading to your wanted course, secure to be emerged, close doors in radio room to secure best condition for sound engineer, position yourself anywhere inside to allow submerging and start the script.
It's moving forward emerged and looking for contacts submerged in your track periodically and use tc to spare your time..
