    Re: recommendation for slide rule ?
    From: Gary LaPook
    Date: 2009 May 20, 20:10 -0700

    No advantage with two sliderules.
    
    Don't be intimidated by all the scales on these rules, most are LogLog
    scales that have no connection with celnav calculations. The important
    scales are simply the D, S, and ST scale for small angles.
