    For celnav I, of course, recommend my flat Bygrave. You can find everything you need to make one of your own for less than ten bucks here:

    Even if you want to use a standard ten inch slide rule then it is advantageous to use Bygrave's formulas and method since this produces more accurate results than the more common sine-cosine formulas. A test was don't and this was proven, see:

    Other posts about selecting slide rules. You can also go back in the archives to May 2009 where this was discussed. Here are links to some of those messages:
