(GUE stands for Global Underwater Explorers --"global" for some of this agency's overhead divers here in Scubaboard means life & the world only revolves around the Caves of Yucatan Mexico, or Florida). . .
You haven't been completely informed... you someone forgot to tell you about France, Croatia, Hungary, Ukraine, Sicily, Italy, UK, several places in Asia like China, Philipines, Thailand, and of course Australia and I bet a whole lot more. So the cave diving world actually really is a Global adventure...
Much of the beauty, inspiration, wonder & diversity of Marine Life are on the coral reefs of this planet between the surface and 18 meters --as novice open water divers, go see them first and as many times as you can before they disappear & die-off. (Only after then, try Cave Diving. . .).
I completely disagree here... After OW, practice a bit, do a cave course and only then try coral diving. That may slow down the killing off of coral a great deal because in cavediving you really get to perfect your finkicks and buoyancy. :cool2:
And besides, looking at stalactities and stalagmites that took thousands of years to form is pretty awesome too...
