    TI-36X Pro Calculator for Sight Reduction
    From: Greg Rudzinski

    The TI-36X Pro scientific calculator seems to work through sight reduction like a programable calculator when using the expression mode. Enter in an expression such as arc sin ( cos x cos t cos d + sin x sin d ) and it is stored automatically in the display history for future use even when the calculator is turned off then on. There are 8 variables available. In the above example x=Latitude t=meridian angle d=declination.

    This calculator goes for $22 new at Best Buy or online. Seems to be a good value for what it can do. My only criticism is that to convert an answer to degrees minutes and seconds requires six button pushes when most other calculators do it in one push.
