Thanks guys
I swear I have tried Manual TDC + WE Assistance, and it was immediately showing me the target ID as soon as I put the periscope/UZO on it... I'll try again and tell you how I got on
I'm currently off Aberdeen on my first GWX patrol, hanging about and waiting for war to be declared
Ho hum... at least the weather has cleared up -- the North Sea crossing was absolutely foul!
