I am very curious about this Bris sextant, and have some questions to its owners: 1. Doug Royer Mon Nov 08 2004 - 13:49:02 EST reports some fixes of amazing accuracy, Somewhere near San Diego, and he says this was "on land". Question: was a natural horizon or artificial horizon used? (I would be very proud to have such precision with my conventional equipment). Other people reported using it when "hiking in the desert". What horizon did they use in the desert? 2. Bris sextant (according to the description on Cassens-Plath web site has some preset altitudes. So that you only need to mark the time. What are these altitudes? How many? (From the manufacturer description I could conclude that there are at least 4. 3. How do you use it? Is it attached to eyeglasses (as shown on the Cassens-Plath picture)? How does it filter the sunshine, without obscuring the horizon? I mean which part of it has shades? 4. Who sells it and for how much? Alex.
