    Geoffrey, Thanks for posting those new links, the old links don't work. 

    There is also this one that still works:


    ​I found that my little hand-held sun-compass was extremely effective. Indeed, effective enough to show in a very direct and quick manner that the deviation for a magnetic compass in Egypt was negligible. Pretty easy to make as well - even though Andras Zboray, our expedition leader, remarked on seeing the compass that, "You evidently have too much free time on your hands!" You need a tall gnomon in the desert as the sun gets pretty high around noon, so I used a small telescopic antenna, which I think is novel, meaning the compass could be easily slipped in the pocket.

    (But do try to spell your own name corectly)

    ​Ha! Yes Gary, Everybody else has trouble spelling my name corectly (!), but I have never claimed any divine superiority in that regard..... ​
