    Re: recommendation for slide rule ?
    From: Andrew Nikitin

    Gary,
    
    British brand UNIQUE offered several sliderules of cheap construction, but
    interesting scale layouts. Among them was so called "Unqiue navigational". In
    addition to normal log scales it featured sine and tangent scales located both
    on slide rule body AND slide. Allegedly this would make certain trig
    calculations easy.
    
    Whould it be more convenient to calculate a celestial fix with this layout? If 
    not, what other navigational calculations would be simplified?
    
    Unique Navigational may be seen on various places on the internet, for example
    here:
