Hi Eikson dont rely on your watch crew or your sonarman to locate convoys
1.when on surface while maning the uzo or looking through the Attack periscope sweeping the horizon keep pressing the L key if any ships or convoys are near you will lock on to them
2.When at perscope depth dont rely on your sonarman your hears can pick up a ship or a convoy at ranges as far as 38 kms away.
When playing any SH3 Campaign as you approach your patrol grid dive to perscope depth for three hours at 2-3 knts and do sonar sweeps yourself its a tried and tested method by seasoned SH3 Uboat Kapitans.
Happy Hunting
