Haha, didn't know that was a thing. Funny coincidence.

- count the number of horizontal lines
- on your raobf disk turn the middle disk to match your distance found with the length of the target
- find the number of horizontal lines that you previously observed on the middle disk (bottom numbers) the AOB is the number located opposite on the internal disc
I hope this is clear enough for you
Good hunt

Merci beaucoup
. Perfectly clear, I probably got the rows wrong first time I tried. One more thing, though: I noticed the numbers on the internal disc only go to 90. What do you do when the target has an AOB greater than that? Subtract the number you found from 180?
