Thanks for your reply. I suppose the definition of what is meant by "capable of diving without supervision" is like asking how long is a piece of string. It's subject to interpretation. Unless both divers have rescue training, are they ready to dive without supervision? I think not, but some certification agencies disagree.
I would think that almost every agency disagrees with you. Only a small percentage of divers take AOW and, under the PADI seqeuence, even fewer take Rescue.
Do you need Rescue to dive at Breakwater (Monterey)? No! Almost every day of the year, there are a bunch of very qualified instructors around to complete that part of rescue that wasn't taught in OW. Other than the beach entries, Breakwater, on a good day, can be pretty benign.
OTOH, I am a big proponent of getting trained to the Rescue level. I just don't think it is an absolute requirement for diving independently. My wife, my son-in-law and I all have Rescue certifications. My grandson will get his in due course.
It's not going to happen and I'm not going to whine about it but I think we were better off with the old NAUI sequence of OW I, OW II, Advanced OW and Rescue. At every level, some type of rescue training was included. I don't know if it was 'expected' but my buddy and I took the entire program essentially back-to-back. And then we dove around the world, independently and on guided tours.
The most important part of Rescue is the part about self-rescue. The idea that I would depend on my buddy to save my life is absurd. The most probable scenario for me is MI and that isn't survivable underwater. No amount of Rescue training is going to change the outcome
I certainly won't run out of air and I pretend I can survive any equipment failure.
We're back to where we always wind up. Nobody over 40 should be diving. The stats are all against it.
