Sticking my nose in someplace where perhaps it shouldn't be, but I feel the need to make a comment about being a "Rescue Diver."
I started a Rescue class last night -- two divers, one of whom took his OW and AOW from me -- and who has, perhaps, 10 dives locally (more dives tropically). The other student is new to me and has, maybe, 45 dives -- including the new PADI Missile Silo Distinctive Specialty (but who had never heard of gas management before!).
This class will have two lecture sessions, two pool sessions and two open water sessions and they'll go through the various scenarios, as I'm sure Matt did in his Rescue Class. I also know that once my two students finish this class they will NOT be "competent" to go rescue someone who is in trouble -- especially if that rescue happens to come 6 - 12 months later. My hope is that, by the end of this class, they will be able to see what situations might get them into trouble and have enough (new) experience to keep themselves from getting into those situations.
And yes, IF they happen to run into a tired diver, they'll be able to help bring her to shore. But doing a REAL "rescue?" Nope.
And, of course, there really is very little diving involved so I'm pretty sure their overall diving skills won't be improved by this class at all -- as I suspect Matt's overall diving skills weren't sharpened at all by his Rescue class.
As far as the other comments many have made regarding Matt's "adventures" underwater -- yes, he needs to rethink his approach to diving IF he wants to become a safer, more responsible, diver. OTOH, if he doesn't, oh well -- that's his choice.
