Aircraft and TC

Captain Nemo

The point I was trying to make is that the settings in SH3 Commander that are meant to manage TC settings for "When Enemy Plane(s) Detected" and "When Enemy Ship(s) Detected" don't affect enemy units as they are supposed to...

No disputing your observations, in fact they're all good. My only aim was to point out to everybody that using a snorkel in SH3 requires modifying expectations and adapting different techniques for managing TC, spotting, navigation and mission execution. Otherwise life will be short and end violently, usually by an attacker you never detect.
