I posted a survey and blog in regards to fitness to dive asking what people thought about annual physicals for divers, the results and comments were interesting and varied across the board. DAN also did an article about being honest on dive physicals also. There are alot of factors that come into play with a person fitness for diving. It is a strenous sport and there possibly should be a high standard for fitness when it comes to diving. I dont think it will change in the near future. The burden stays with the individual diver as to their prepardness to dive and their ability to monitor their air supply and dive within their limits. That burden cannot be placed on the dive shop or charter operator. That rest with the diver who assumes the risk of taking to the water and being ready to handle an emergency, dive within their limits and training.
