Hi Patti,
There was a thread on this a while ago -
http://www.rebreatherworld.com/rebre...highlight=peru. The consensus was that there wasn't much doing, OC or CC. A shame, as I'd wanted to give it a try on the next family visiting trip.
Since then, someone has posted on Rebreather World who lives in Lima and IIRC, dives a Meg. He is NickT on here. He'll clearly know more about it
Cheers,
Gosh doesn't look promising....
