    Re: recommendation for slide rule ?

    Good point.  On my boat I carry an old 6" rule for one purpose -- converting seconds (found on some large-scale charts) into decimal minutes for entry into my GPS.   WAY faster than using a calculator and/or reprogramming my GPS to accept minutes and seconds (and then unprogramming it).   An ideal blend of old and new technologies...

    Alan,
    $25 should get you a functional K&E 4080 which does trig in degrees and minutes. If you are ok with degrees and tenths then a bamboo Post Versalog is good. Lots of nautical applications. Time, speed, distance, and ETA are easy and fast. CN is accurate enough on altitudes below 30*. Great for azimuths and amplitudes.
    Greg
