Help Classifying a Contact

[ddiplock]

Hey guys, I'm in the second campaign mission for the Russians in Sub Command, track the leaving US submarine.

Now, I admit I have been using a combo of my sensors and show truth on the map until I get comfortable with playing properly, turning show truth off for exteded periods and playing using only my sensors, show truth only comes on for a few seconds to confirm how accurate my detections are being. I have detected the US submarine, and classified it on the map (without show truth on). I know it is a 688i class submarine, yet in my narrowband sonar, with the filter on, its throwing up a load of merchant class ships such as cargo, oiler etc etc.....I already KNOW this contact is the US submarine because of the show truth I have.

I have designated the contact on my broadband sonar to keep track. I have input 7 turns per knot into the DEMON sensor but I'm getting wild speed estimates of 25 knots, the show truth shows the 688i to be submerged and going at 8 knots. Basically, how can I successfully classify a contact so the DEMON system actually KNOWS what contact speed its estimating?

I know its the 688i, but with the Akula it seems I can't find a way to physically input that classification into the system, and as I said with the filter on, my narrowband is throwing up the totally wrong contact classifications. I've turned filter off and selected 688i myself, but doesn't seem to be working.

Any help?

Thanks
