    George, I would hope that this group would discuss ALL aspects of
    navigation, from ancient techniques to modern ones, from kamals and
    lunars to self-compensating electronic compasses.   I like to learn of
    new technologies but I am also fascinated by the solutions to problems
    people developed in earlier times (think steam locomotives vs diesels or
    sail vs power ships).   As I'm sure you've observed, there are however a
    few troglodytes on the list that seem to think that the use of any
    post-1800 technology for navigation will certainly fail, causing ship
    and crew to die a horrible death.
    
    When this thread on self-compensating electronic compasses started, I
    knew very little about them except that some of them had the
    drive-in-a-circle technology for self-generating an internal deviation
    table and automatically applying it to their displays.  I've learned a
    lot about the technology since this thread started a few weeks ago.
    While equipping my own boat would be very far down on any list of
    desired "toys," it's good to know about the technology.
