It's driving me crazy that people keep saying there is no dive insurance for dive professionals in Cozumel. THERE IS DIVE INSURANCE THROUGH TRAVELER EMS/DAN WORLD! Sorry for the caps, but people, please know that DMs and others can be insured. I know because I pay the bill for it for the dive professionals for a Cozumel dive shop. I spoke personally with DAN when they made this change a few years back. DAN made the decision to have another organization provide dive coverage in Mexico and Brazil. I know there are local advocates trying to change it back to DAN coverage and I hope they're successful, but in the meantime, coverage is available through Traveler EMS. PERIOD
