    This is not always so:-) As a person who does this
    just for fun (as most of us do, I suppose)
    I learned several reduction methods, almost all
    commonly used methods. Except special
    navigation computers:-)
    
    I find using tables just a little bit faster than using
    a calculator. The speed and the number of blunders
    with both methods
    depends VERY much on
    how frequently you practice.
    That's the main reason why I would use ONE method
    during a single trip.
    
    Calculator gives you some extra accuracy which is
    not important. It also has
    several other uses, besides sight reduction:-)
    Of the tables I like very much the Complete on Board,
    because it contains much more than sight reduction
    tables and almanac, in a very small, convenient package.
    The main disadvantage from my point of view is that
    you cannot do the Lunars with Complete on Board.
    
    Much depends on which method of
    sight reduction gives you more fun. I imagine that
    some people do not enjoy the process of sight reduction,
    especially plotting the position lines.
    To them
    I would recommend a special navigation computer
    which probably does all math for you and just spits your
    co-ordinates out:-)
    
    Alex.
