People are no more likely to have a DCS problem here than anywhere else, but as the good Captain says there is a recompression chamber right here in San Pedro, the only one in the country. Visiting divers should try to fit in a (voluntary!) visit there, as it's a fascinating place and they're only too happy to show people around.
I do know a bit about some of the people the Chamber has treated recently and generally it's a case of people doing things right but maybe a little too aggressively, too early in their trip. There seems to be a pattern of people relying too much on others for their dive profile and not being sufficiently "bullish" themselves - it always worries me when I see divers without a computer, and especially so when they don't have a depth gauge or a watch either. Astonishingly this isn't uncommon in the Blue Hole, a dive that more than any other here does need to be taken seriously. Not least because the Chamber is back here, 60 miles away.
Perversely dive insurance seems to be a minority choice. When you can get a year's cover INCLUDING non-dive related accidents for about US$100, can this be down to anything other than ignorance? If dive operators agreed to make it mandatory before anyone dived this problem would disappear immediately - I do for technical divers, but for others it would be commercial suicide unless other operators followed suit.
San Pedro is a diving destination, and most people living here owe their livelihoods directly or indirectly to it. I'd like to see diving issues given a higher profile by everyone here - whenever the Chamber puts on a seminar or demonstration to do with diving practices and safety it's very poorly attended.
