@My Sunshine . Very sorry to hear your wife has passed away. Feel sad for you and your family. Thank you for posting your detailed account of what happened. I believe this will help us all understand what happened vs the speculation we would normally read. Sometimes these articles are people passing away due to medical issues and we can help ourselves feel better by saying "He/She passed away doing something they loved" But that doesn't sound like what happened Gloria. In My Opinion - Dive shops that mix experienced and new divers together and have only one Divemaster on the dive adds some real risk. The experienced and most likely the divers with the best (least) air consumption don't want to go to the surface early because of another diver. Leaving a single dive master with a choice to make. Take the person to the surface and leave everyone else at depth - or take everyone to the surface. There is no win. My advice to the new divers would be - only dive with a company that takes two staff underwater on every dive. Then you should have someone to go to the surface with and that person would stay with you. The Cancun side - Riviera Maya - has better visibility. I have been on many dives where the dive shop has asked me to be the last diver in the lineup under water. They see my Cave Certification and they only have one staff member underwater and they ask if i will help - and I am NOT a dive master and they know that. I am always happy to help another diver. If that means we are exiting early then that's ok with me. I hope that everyone who reads this article learns something from it. Even if it is a simple as an attitude change to those new divers we dive with. Again - very sorry to hear of your loss.
