And i want to ask another thing...i saw this video and observed cool bearing plotter in navigation. I the description of the video is that he doesnt use any mods so i ask how to switch on this instrument.

Thank for your answers.

The SD air search radar is an AI function only and that is where your crew announcement came from. The SJ surface search set is both of the scopes you can man, and only becomes functional as the war progresses, and your sub actually has it installed. Yes, that is a bit confusing and to top it off, the buttons are/were mislabeled. The SJ A-scope is the green one with the horizontal grass line. It's used for range finding and has to be directed at the target to see the pips. The PPI (plan position indicator) is the red one with the sweeping clock like hand. This is a newer scope added to the sets and gives you a map, or plan view, showing bearing and range.

So, when the crewman says he has a radar contact, it's likely an aircraft. Look on your map view for a very fast contact and dive to evade.


This one describes the types in general with specs.

This one shows more theory and indicates the SJ A-scope was for accurate range finding.

The Cobia link has photo's of the actual set, but I don't see any graticules other than bearing ones on the PPI.
