    Re: Finding IC for A-12 bubble sextants

    Dear Frank,

    Here you give an explanation of the 10-seconds delay option:

    ...If you're working alone, call out (aloud or in your head) "zero" and then start counting seconds until you hit 10. Then at that instant, tap pause. The time will be displayed with the notation "-10s". ... The displayed altitude is correct for the moment when you called out "zero" at the start of your ten-second count.

    I never saw the altitude value to "jump back" - even with the 20-seconds delay and altitude changing very rapidly. It just freeses when I tap.

    Why is that?

    Regards,
    Tony
