Can you still get those compass and clino's? i.e. the ones you can look though, I am in need of surveying kit myself, now that caving appears to be returning to normal, or soon will. I have a laser range finder, but need a compass and clino, if disto x cannot be bought now. Slower surveying but it's better than nothing. At least I don't have to use a tape measure! Is there a commercial outlet, would these work for the poster too, though they are not Disto x's if it's Ghar Paru, I am sure you can explain that you just meant surveying kit.
If there is only one for sale, though and the original poster wants it I suggest you sell it to him first as I am sort of hijacking the post here.
