    Re: sight reduction calculator
    From: Irv Haworth

    Hello
    
    In my opinion the best hand held calculator for celestial /terrestrial work
    is the hP 41 C or 41 CX with the navigational pack. These calc. are no
    longer made but are generally available on eBay etc. (Oddly enough the nav
    pack has a flaw...calc. GC dist/course say every 10* long. between eastern
    and western hemisphere...).
    There are other and newer hand helds avail at higher prices. STARPILOT is in
    my opinion is a great program...but unless you have fantastic vision you
    will need a magnifying glass to see the data on the screen of the TEXAS
    INST.   TI-89 Titanium.. (I bought the pgr for use with a laptop...after
    buying the TI 89)
    Regards
    Irv

    Subject: [NavList 4464] sight reduction calculator
    
    
    hello every one,
    
    i 'm trying to  get a hendheld calculator to expedite my sight reduction
    work.
    if i use a regular sciencefic calculator it take me like 10 minutes per
    sight. some time i want to trevel light so a calculator will be a good help.
    i can see on internet are a lot of programs ,softwhere   and many
    others. the problem with the little palms or pocket pc they depend on
    recargebile battery, that mean if you  are somere isoleted you ca not use it
    for long time. i see  the starpilot as a good alternative for a long period
    of time but reading the instruction on internet i see  for sun  is upper
    limb or lower limb, i do use a bubble sextant so i do not see that option.
    any advice will be more than wellcome
    thank you
