I wonder, if something is very far away but still in reach of the manual hydrophone (you know when you man it yourself), will a contact appear as very, very faint sound, or will the green light turn on and you hear it no problem?
I believe in silent hunter III a contact always started out as being very faint...had some great moments back then finding something out there
Somehow I got to believe SH4 was different and I stopped doing it...but maybe I was a bit lazy too
