Magnetic torpedoes, though sometimes unstable before 1941, are real lifesavers when you cannot line up for a 90 degree shot and risk having your eel just deflect off the hull of your target. in this case what you do is identify your ship via the scope/UZO, and click on the word "ship" in your notepad: this will open your recognition handbook directly to the page you are looking for. Then it is simply a matter of checking the ship's draft, going to the F6 screen and adjusting your torp running depth to 1 to 2m lower. Be aware that in rough seas the swells can raise and lower your targets and you risk having a mag run 5m under and not detonate. Also rough seas tend to cause them to detonate prematurely before 1941...

BTW, Yes, you do not have to lock your scope, wherever you aim it is where the torps will head to, just ensure that your gyroangle is between 355 and 05 degrees to have your torps come out as straight as possible...

Hope this helps and good hunting.
