Whew. It's hard to keep up. Hey, guys, I get the end result of the tech divers your agency makes. We have a policy, which is "dive to the limits of your certification". Trouble is, what are those limits. I found out this morning about PADI's new tech 40, 45, 50, 65, and 115 programs (humor there, don't get your panties in a bunch). What I remember is, tech 40 allows you to dive with doubles, with no more than 10 min of deco. Tech 45 allows deco gas, and tech 50 allows something else. TDI is changing things up too. It used to be, deep air, advanced nitrox and deco procedures, trimix I, trimix II, and expedition trimix.
Please please please put the limits of your programs somewhere easy to find. On your c-cards would be a likely place. I can advertise the depths of our planned dives, but I'm NOT a tech instructor. On purpose. I don't know what folks' different certifications mean, especially since everyone seems to be dividing them up into more and more classes. That's a topic for a different thread. I know what the recreational limits are, but I have no idea what some of these training agencies cards mean. And since I'm the guy who takes these folks diving, I kind of need to know.
Nope, it's because folks ask me which trips are appropriate for them. Someone with a Adv. Nitrox and Deco Procedures card isn't certified to 250 feet on the Wilkes Barre. It is necessary for dive planning. We like to let the group set the destinations. They are going to need gas from me, they are going to need rental cylinders from me if they are flying in, we are not a day boat.... My TDI card says I'm trimix certified. My IANTD Card says I'm normoxic trimix certified. One of them limits me to 18%, one to 16%. Damned if I know which one is which. Got them both on the same dive, though.
Dont you actually ask the divers what they are qualified for?
Ummmm....Yeah, but that doesn't really mean they all know....
Seriously. Some of my newer cards list a max depth. None list a minimum O2 content. I think normoxic is 16% or better, but it might be 18%. I just can't remember, and it's sometimes hard to find standards on websites. When I have to deal with many potential certifying agencies, it's just nice to know what folks are certified to dive to. I get asked if a normoxic diver (200 feet) can dive on the Rhein, Araby Maid, etc. The answer is yes, but the bottom of those wrecks is 240 and 220 respectively, so I just need to warn them of what to expect....
Nope, it's because folks ask me which trips are appropriate for them.
It's an easy fix. Ask them what their limits are considering their training and experience. After you get that info, you can tell them which sites fall within their limits. Once you start telling them they are qualified for specific sites, it appears to me (not a lawyer) you'd be opening yourself up to more liability. Seems to me (I'm still not a lawyer) you'd have less liability by stressing they need to stay within the limits of their training and experience, providing them with site info and a boat ride without making judgements on qualifications except when someone is obviously not qualified to make a particular dive. I would not tell someone they are qualified for a dive. I would let them make that determination.
