Four bearings...

[Shkval]

Well, I'm playing SH3 again after a long time, with GWX3.0 gold an MaGui mods... and I have a few questions, first, this situation in picture, contact is moving away and when I try to copy first bearing on a symmetrical point it does not intersect with last bearing... what does it means and what should I do?

Second question is does anybody knows some good tutorial about these tools in MaGui mode, attack disc, this second "brown" disc that has something to do with AOB,...and this third disc attached to periscope?

I got this Angriffsscheibe_Handbuch_3 pdf for attack disc but it's pretty different from this one in MaGui, and off course two "main" tutorials about hydro-hunting... I need more...

I'm practicing the four bearings method because I like this "mathematical" approach of aiming torpedoes and because I intend to survive the war . I'm not a total beginner but for the first time I'm playing with "map turned off" feature... and it's bloody difficult... yesterday I did mine first "blind" hit at 4,5 km .
