Yey! That's just incredible!
REM coupled with RM&A and Sober green Crew Training is in fact the more accurate it could be!
My hydro guy just needed few missions to handle and learn the hydrophone...
The more he gets points with RM&A and training % with SGCT, the more i can get my surfaced contacts
Approaching Scapa Flow, he can almost detect everything now.
But at start, i was really thinking something went wrong with my install

So sorry to have bothered you once again with my problems.
