(There is a bubble camera with a liquid, of course). My main concern was not taking shots from an airplane with a bubble sextant (though this is an interesting ides) but transporting my ordinary marine sextant when I travel. I used to pack it carefully and check in to the luggage. But since my friend had his binocular in a checked in siutcase disassembled by some security in Germany, I do not do this anymore. > Your trial results are pretty good. > On land anything better than 4 NM from GPS is good and What do you mean "4nm from GPS" ?
