Do you play with auto-TDC or without?

[Captain J. Borne]

I usually turn the TDC on and use the periscope to aim. You can't be too jumpy on this, its not like you just see the target then aim and fire, especially when they know of your presence (since other boats in the convoy have been attacked) and they are doing S patterns. But by using the TDC on option, aiming correctly, identifying ship, and adjusting torpedo speed and impact fuse, I am very effective, rarely do I miss, and I conserve my torpedo's by only using 1 torpedo per ship and just wait for the boat to sink rather than using another and doing it quicker.

Iv'e tried using the lock and weapons engineer but they always seem to miss and be way off. Plus I like the realism.
