Thanks UB. Yep i finally figured out SCU. I replayed the scenario and discovered that that the auto crew does not pick anything up on the sphere array unless the towed array is deployed. I am experimenting with it right now with both surface vessels as well as submerged. No matter how close I get to a contact they do not report it. For me the fun is about the hunt and being able to enjoy a dependable crew. I like the concept of being a virtual CO and not a sonar tech, that is not what CO's do. But I understand that the game is built around sonar and basically no other real tactical simulation for submariners, which I hope someday someone will
design, but until then, I have to improvise.
