Don't know 'bout Doug but I find LX- computers give you fairly exact
wind indications IF you circle steadily keeping bank and airspeed as
constant as possible for a few circles. Then I normally get very
silmilar values on the LX20 and SN10.
Not being careful doing that the values often are 20-40% apart in
strength and 20-60° in direction. Especially in weak wind the values
can differ 180°!
