It's time I finally learn (Manual shooting)

There are a number of different ways to do things, and each tool (3 minute rule, nomogram, calculations) each have their uses.

My primary manual attack method is the zero gyro attack selecting the approach angle (e.g. 90, 45, or in between depending on the situation.) But when useful (or to keep in practice) I also use the TDC (bearing, range, AOB -with course verification), passive sonar only methods, and Kentucky Windage for snap shots.

I find it useful to understand what is going on in each attack method and the inter-dependencies between parameters (like AOB and target course) to help me decide what type of attack to make, what neat thing to try (hits on 3 targets simultaneously), and how to proceed after my attack (snapshot ? as my periscope goes under at the tanker veering out of column and crossing my stern after the first targets were hit.)

Very true

Wasn't meant in a disrespectful way at all but more like:

When learning manual targeting this is by far the easiest way to get speed and true course.
Once you get the hang of it you can start with other ways of get the same results without second guessing the input.
