    Re: Suitable Sextants
    From: Alexandre Eremenko

    In my previous message on the subject I did not address
    the cost-effectiveness.
    And the questions of "effectiveness" at all.
    (Because I think that all this sextant business is not about
    effectiveness. A GPS and a battery-powered spare GPS is by far the
    most reliable and most effecdtive tool of navigation.
    Or, if you are preparing to the doomsday, have TWO SEPARATE AA-battery
    powered GPS, each at $140 at K-mart).
    
    From the effectiveness point of view,
    Bris sextant is really a revolutionary invention.
    1. You can make it yourself at almost no cost and without any handiwork
       skills.
    2. I bought THE last one sold by Cassens-Plath.
       But I can give you detailed instruction how to make
       one yourself.
    3. It fits to your T-shirt pocket.
    4. Never needs adjustment or repair. You can drop it on the floor.
       (the only concern is not to loose it, it is so small)
    5. I believe it permits you to determine your position within 5-10 miles
       in the good weather conditions. Which should be enough for
       a landfall in an ocean crossing or even in  finding most islands.
    6. I am ready to publish detailed instructions how to make one and
       how to use one, if there is any interest.
    
    Alex.
