    My favorite bubble sextant is my MA-2 which is hand held and which has
    the averager from the Kollsman Periscopic sextant. In fact, it is the
    Kollsman Periscopic sextant without the periscope. The averager runs
    for two minutes and averages 120 sights automatically. It does not
    need electrical power except to light the bubble for night sights. You
    can connect 3 nine volt batteries together to supply power for this
    The averager is mechanical and runs off of a clock spring.
    ther is one for sale now on ebay:

    I'd buy it but I already have too many sextants.
