@GRENADER The tool also exists in Magui mod and it has a readme, here's what it says :
aob tool
--------
the aob tool is attached at weapon officer's orders
how to use this tool
--------------------
1.come to a dead stop.the u-boat must be totally stopped.
2.take the first bearing(B1) of the target and start the chronometer.
3. after x time (any time you want) take the second bearing(B2)
4.after EXACT x time take the third bearing(B3)(note:meaning, if your second bearing was taken after 30 minutes past then you will wait EXACTLY 30 minutes to take the third bearing )
5.calculate B2-B1 (difference between second and first bearing)
6.calculate B3-B1 (difference between third and first bearing)
7.now go to the aob tool.turn the inside disc until you line up the B2-B1 ON OUTSIDE disc WITH B3-B1 ON INSIDE disc
8.read the aob in the small window of the tool
IMPORTANT:the aob that you read is the aob at FIRST bearing.
notes
-----
i.the target must have move at least 5 degrees to take the second bearing.(B2-B1 must be larger than 5 degrees
ii.the tool is very sensitive.that means that if you see the target at 12,3 degrees this is the value that you will use (and don't say 12).the more exactly you are at the bearings...the more acurate will be the aob that you get
iii.with this tool ,you get only the aob(don't forget,..at first bearing),not the true course of target.all that you know by now is that the target is moving at a parallel line.when you calculate the distance ...you will be able to draw the true course of target

@ericlea : good job with the draggable watch,
, does it work on any version of ARB mod or only on this WAC version that you are improving ?
