opencaching? really? in GPS technology and devices Posted December 8, 2010 · Edited December 8, 2010 by Berta, Nick and Zoey I just zoomed out to where the entire Earth is shown and theres 2248 caches listed. Lets see GC do that in under 5 seconds. I know, much larger databases require much more crunch time to build. But, then again I only have to zoom out a little bit where I lve before I get the "You have exceeded 500 caches, zoom in" message.
