Extremely!

I just have a sound contact I will try to apply this advices.
Weather is bad , visibilty is poor, precipitation is high in one word ideal for testing the knowlege.

Will report wright back.

Ok I asked for the 1st bering it was 350. After 6 min the bering was still 350 , after 4 more min it was 349 and afther whole 20 min(6+4+difference to 20) it was 348.So that my first angle will be 88 degrees right( not so good angle).Is this good so far or am I doing something wrong.

Yes, and I have to ask how big is the M diameter.Do I draw the M circle before I get the 2nd bering line or not? On the video i saw that he draw M ciircle and the triangles and just added the angle later on.

My 3rd bering after 20 min is 340.So my new A2 is 82 degrees(good angle if I may add).

So now I got the course angle of the target it`s 5 degrees.

And when I inserted the angle on the actual map I got the 2,7 in between 1-2 nd and 10,1 in between 2 and the 3rd.

I draw imaginary "fourth bearing" ploted the 5 degree angle and I got some nasty sh`t.
I don`t know what I do wrong. I will have to read this tread over and over , and practise.

Is it important when I caught a sound contact, what if he is of me in the middle distance?
How big the circe on the contact should be 20 km or less?

Last edit:

Omg I found a good exchange rate targets, just as the distance was wrong.Is aob angle in fact the angle of 5 degrees in my case or not?Because his angle on bow was 95 confirmed later on.
