Does not work. Throw manual away, this does not work either. While in TBT or scope view, ID the vessel and get range. This will also update the bearing. Determine AOB. Wait about 30 seconds and to this process over again. Once done click on the little watch found on the range/AOB dial you were just using. This will give speed. The calculation for speed is only as good as your range imput.
