I just had to share this with all of you, this is the "BRIS-sextant". It weighs just 3 grams and can be used as a position-finder (as a GPS). This will not be for everyone, but for the SUL-hiker or those who like navigational instruments it might be of interest.
15 grams is the weight of the sextant, string, instructions and the film canister it is stored in!
Here the inventor tells about his sextant
Don't have a horizon? Well, heres how to make a artificial one (look from 02:15 and forward)

I saw that on the second picture it says that the sextant weighs just 3 grams. The 15 grams (written in the manual) refers to the weight of the sextant, the lanyard, the instructions and the box it is stored in (a film canister).
Just so everyone knows that are interested in this product, the inventor is sailing his homemade sailingboat across the Atlantic ocean and won't be back for a while. Yet I suppose you could send him an e-mail and maybe someone at home could send you it.Aug 4, 2011 at 1:37 am #1766057
Had to bump this as I believe a lot of bpl-people are out enjoying backpacking and have probably missed this :-)Aug 4, 2011 at 6:34 am #1766091

Chris, Thanks for posting this.Sep 2, 2012 at 1:04 pm #1908473
Has anyone ever actually used a Bris Sextant on land? I guess that people will still prefer a GPS, even though the Bris Sextant is so small and light. You still need a compass, map, calculator (or slide rule, abacus, etc), pen/pencil, paper, etc, so maybe after all the "accessories" are included, the GPS still might win. Wristwatch style GPS's are especially light and small.Sep 2, 2012 at 1:07 pm #1908474

"Wristwatch style GPS's are especially light and small."
But the size of the display screen makes them difficult to use.

If you want longitude I believe you'll also want a chronometer.Sep 2, 2012 at 6:42 pm #1908558
