Over the Christmas holiday I had a friend and her husband go to Cozumel. While there they completed 4 days for diving, on their last day her husband ran out of gas at 97 feet. They had been at depth for over 10 mins, per her recollection she was not 100% sure because they did not have a computer between them. When he ran his cylinder down the DM instructed them to use her Octo and ascend, they performed their safety stop per their console at 15 ft, which she said was probably only one min or two max. They got back on the boat and waited for the other divers to return. After their surface interval they completed their second dive without incident.
The next day they flew home to Colorado. She had a splitting headache and eye pain for 9 days and went to the local hospital where the ER doc was a diver and asked the correct questions, luckily the hospital has a chamber. She was sent to the chamber for 6 hours and is feeling much better since then.
When I spoke to her I asked if she had called DAN when she started feeling ill in Mexico and she said they don't travel with DAN. I was a bit flabbergasted by the entire situation. I am still a newish diver and they have been diving for years and apparently they "just trust the DM" to keep them safe. The third piece of equipment I bought was a computer, after my mask and fins, per recommendations on this board and others. I guess this is more a question, is it common to holiday divers to not have computers/DAN on their trips, or are they out layers?
Edited: for buddy breath misuse.
