Ok next testing AOB at zoom x1.5
Ship lenght is 120m
Range is 850m
So 4.5clicks x 4 =
18clicks
= AOB at 18.5deg
Actual AOB is 112deg starboard
so 112-90=22deg or 21clicks
21clicks /4= 5.25 clicks rather than the 4.5 shown.
Is this close enough for AOB
Do you think that only the vertical clicks need changing
