I've not run out of money yet, I've still got change from �100 having bought the theodolite, tripod, sextant and quite a few extras. I'm now a dab hand at finding where I am anywhere in the UK (when the sun shines ... if the sun ever shines), I can strip down a theodolite and rebuild it and not only does it still work, but it is even accurate!! Prism? What about a small mirror and some blutac? ummmmm... don't fancy jagging my eye onto cut glass ... but hang on my wife's got a dental mirror, I wonder if she will notice if it gets a slight modification? --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to NavList@fer3.com To , send email to NavList-@fer3.com -~----------~----~----~----~------~----~------~--~---
