I have been working a lot with the hydrophone (see my tutorial at
http://www.subsim.com/radioroom/showthread.php?t=107303) and although many people say the qualified sonarman hears better, in my experience this is not the case. I made some test missions in order to find out whats the difference between a greenhorn and a qualified veteran and I was surprised, because it seems that even the green sonarman can pick the contact at the same time (or even sooner) as the veteran. so I think the dev team did not simulate thoroughly the differences in experience, at least for sonarmen. dont crucify me, this is just my oppinion
