Thank you for the information. I emailed a couple of dive shops in Cozumel to see if it is possible for us to do a day or two of just shallow dives before going a lot deeper. We went to 80 feet when we were there last time, but want to ease back into it and prefer to stay shallower at first. We'll see what they say. I know it depends on the desires of all of the divers on the boat.
Thinking we may have a better chance in Puerto Morelos since most dives are shallow.
The larger dive ops, with multiple boats, try to put people who have similar skill levels in each boat. Dave Dilehay (Aldora Divers) and Christi (BlueXTsea) are both shop owners and regular posters here, and have lots of fans. You might want to include them in your list of people to email.
One question about the cenotes. We've snorkeled in them before, never dove. Do you have to dive way back into them, or can you stay where you can still see light? Any open cenotes to dive that aren't dark and scary? How deep usually?
Thanks so much.
Because the cenote tourist dives are aimed at people who are NOT trained for overhead environments, there are rules in place to maximise safety.
All dives are done in the cavern zone. This means that you are always within sight of sunlight.
Guides must be full cave certified and dive in full cave gear - long hose, doubles, etc.
No more than 4 divers per guide.
All divers have their own light source.
Cenotes like Chac Mool and Dos Ojos are very popular for tourist cavern tours. Most of them are shallow. 30-40 feet. The water is clear, with visibility 500+ feet. It's cooler, with water temps in the upper 70's. There is no current.
Your bouyancy needs to be good enough that you can keep from slamming into the top or bottom, but the tour areas are generally difficult to silt up.
Tours are in areas where divers can always go 2-across. No narrow restrictions. But if you're claustrophobic it's probably best to stay out.
