I've never had a problem using high TC in enemy water, cept early war without radar. Your default values for enemy contact should always protect you, simply, you get a contact, TC goes to 8 or however you set it. Once I get radar I often use 3000 TC to roam around. Now, when in an attack, I seldom go over 64.

I can't explain what happened to you. Even in stock your crew should warn you in time. Course, most of us know how to read lag as a warning. Now if you spot a plane or ship, think you're safe and crank up TC, can be a quick way to die.

Groups don't spawn inside your detection range. They spawn when the max limit of your detection range comes in contact with the group. This will cause lag, the bigger the group, the more lag you will notice. However, your crew will only call out to the range of equipment or visuals on board.


If you had air and surface radar, what happened doesn't make much sense
unless you're making mistakes. The only time I've died not knowin what happened while using TC was hitting land, a mine or getting to close to a shore gun. I have died using TC early war without any radar type, even though crew gets a visual on plane or ship, I may not have time to get dived.
Early war with TMO, often escorts will blast you before the crew gets a visual, so you have to be careful.
