I’m totally hopeless when it comes to torpedo attacks…

In the years and years of my on-and-off playing of this game I don’t think I’ve ever made a successful torpedo attack on a target. I don’t want to use the auto solution because that’s cheating IMO. I’ve watched and read plenty of tutorials but somehow that knowledge doesn’t transfer to actual gameplay for me. The sheer amount of dials in the TDC is dizzying to me. I just draw a blank whenever a target gets spotted. I could go on and on but that’s the gist of it.

Anybody got any words of wisdom for me?
