Dave, Jessica, Robin and myself went to Limon to locate the anchor lost by a freighter about a week or so ago.
We made our search plan, had all the information and equipment that we needed and under the scorching hot sun took the boat up to Limon.
We anchored near the gps location given to us and, Dave, Jess and myself got our scuba gear and went in to begin the search...
Five minutes later, we were out...!!!!
My dive computer showed the depth being 14.6m - unfortunately, I didn't know this until I resurfaced as it was PITCH BLACK from 7m down and none of us could see any of our instruments (depth gauge, compass, contents gauge - nothing).
Totally unprepared for absolutely NO visibility Dave and I tried a second time but to no avail - we surface, abort the search and return, a bit deflated to Puerto Viejo.
None of us had ever dived in those conditions. The best way I can explain it is sit in a dark room, close your eyes and then 'double the darkness', that'd be close.
Then, because we're underwater with no idea of depth, direction, length of dive, no idea on air consumption, and, once you are off the seabed, you can't tell which way is up it doesn't make for a pleasant environment.
Oh yeah, did I also mention there are Scorpion Fish around here, someone also mentioned a possibility of Tiger Sharks and crocodiles... ah well, maybe next time!!
