It just seems realistic. As the Skipper, I hear that sonar bearing report and I am processing it all in my head in relation to my "vision".
Even hearing reports of sonar contacts changing heading and speed is valuable.
The Sonar Shack needs a manager. (Where the #$%^& is my XO!!!)
P.S. I also think it will bring more game immersion to the player who is in the Control Room.
