Clearing the TDC
 

This is probably a moronic question, but...how does one 'zero out' the TDC? I missed a target today that I could've hit if I could've blanked my data and just fired down the zero bearing.

I tried hitting the little red button on the Position Keeper to turn the thing off, but my torps still curved away...

If you want your torpedoes to go straight out, send AOB 0 and target bearing 0 to the TDC. To send bearing 0, point the scope at 0 and send range, it doesn't matter what range, as long as the PK is off.

Gotcha. Damn. Was hoping there was a way to quickly just 'set for default'.
