Diver Dennis:
TSandM, in my opinion you can have a terrific buddy with all the skills but until I saw their reaction in a panic situation, I would always have a little doubt. That said, I do have a group of people I dive with in Mexico from time to time that are very well versed in the dark art, joking, and I know have experience in overhead and cave dives as well as emergency situations far beyond what I have or will experience. I know they can take care of themselves and although they dive in teams 95% of the time they could handle themselves if they were alone. They know me as well so they don't worry if I'm not in sight all the time. My point is I think there should be a little solo diver in all of us because trying to plan for every eventuality should include what you would do if you found yourself alone.
For photographers, we can share our pictures with everyone after the dive.

A young couple met on a dive boat while on a dive charter near Catalina Island, California. Because hormones were quite active, and the chemistry between the two was in sync, the couple was thinking about post-dive activities and not about their diving. The girl was a novice and was depending on the "macho" male for her safety. During the dive, the girl ran out of air. So, in a near-panic, air-starved state, she went to the man she had dreamed about and gave him a very vigorous "out-of-air" signal. Unfortunately, this guy had only been trained to share air with an octopus (single regulator buddy breathing in many circles has been designated an "unnecessary skill") and his secondary regulator was in the shop. So, when the object of surface fantasy approached him, he had no octopus and thus, no available option to assist her with her crisis!
So, to defend himself from this approaching air-starved-dive-parasite, he kicked the girl in the chest to drive her away from him. She then bolted for the surface and embolized on the ascent. The good news was that Catalina is one of the best places in the world for emergency management of dive accidents. Fortunately, the girl was rapidly transported to the chamber on Catalina island. After regaining consciousness in the chamber, she told her story to the chamber attendant and he told the story to me.
Now, it turns out that this particular chamber attendant is a real 'hard-***" about dive safety and training procedures. This was, historically, at a time when single regulator air-sharing was first being removed from most recreational training. He wrote the training agency involved and asked them to comment on the male diver's behavior. The response he received was. "Our diver acted appropriately 'cause buddy breathing causes accidents!"
The points are:
1. 100 feet down, out-of-air is NOT the appropriate time to find out about potential air sharing difficulties.
2. The buddy system works best when each diver is self-reliant.
3. Depending upon strangers (some cave divers called it a "trust me dive") is generally not a good dive travel strategy.
So, it is just good practice to establish signals and emergency procedures before a dive.
