+3l diesel Posted July 27, 2016 Share Posted July 27, 2016 Interesting article claiming a relatively huge distance discrepancy. I understand surveyors use GPS to within millimetres. http://www.abc.net.au/news/2016-07-28/aust-latitude-longitude-coordinates-out-by-1-5m-scientists/7666858 Quote Link to comment

Interesting advice, but incorrect! Why? Because the hider's gpsr was *also* off by 1.5 meters! The only adjustment needed is to look 7 cm NW of GZ (check article) for each full year between when the cache was placed and the day of search! So there's no excuse for slower finds!

Whatever gave you the idea that I didn't spend the entirety of that three weeks looking for it?!?!?! Quote Link to comment
