CT ... one of my quirky personal beliefs is that there are very few social activities. There are social people. Social people will socialize while engaged in whatever activity, while less social people won't. Same activity, same rewarding feeling for the participants, different amounts of...

Sigh... I really should just start writing in Arabic. :) 1) Both parties must get something out of any relationship. Mentoring included. That's reality. 2) A lot of people have a an image of showing up as a noob and being taken under wing and mentored simply because they are noobs. That's a...

You mean you don't believe the man averaged 8 dives a day over 40 years? Shame on you for being such a Doubting Thomas!

What does PADI have to do with anything? :ohbrother: For that matter, where did you get "isn't of value unless you paid for it" out of anything I said???? :depressed:

NAUI and SDI/TDI have diver lookup features. Not sure about any others. NAUI Diver Lookup https://www.tdisdi.com/userportal/?type=2&flex=cert_search_sdi

Definitely didn't mean to imply you did. It would shatter my perception of you to find out you were one of them. :) I was doing my usual circuitous and oblique hinting that, because the rewards you cited aren't directly tied to helping (as objectively measured) but instead to the perception of...

My own theory is that dives are logged because a lot of early civilian divers were ex-military and pushed the habit onto recreational divers because it was habitual for them. That said... As a new diver I think my logs are very useful in figuring out what various gear changes really mean to...

There are two issues. First treat it as though the risk starts at some low but non-zero value and goes up exponentially. So from .2 to 1.2 PPO the risk is fairly similar and fairly low (but not technically zero, just so close to zero as to be ignored), then 1.3 has more risk but not much more...

Those are great and do both of you credit. People are lucky to have you around. The social rewards are a big incentive. They are also double edged swords. They keep people like you coming back to help new divers who really need it. The flip side... when I had my sailboat in Long Beach harbor I...

I think the mentor idea is a fantasy most of the time. The idea of being taken under wing and shown the ropes and five other cliches is very appealing to someone just starting out in any activity. However, in order for anything to happen when it comes to human interaction, both parties need to...

It's all risk. My suggestion... read this: Scuba Dive Medical Articles

Personally, based on the question LL is asking, I'm not sure the class would really help him understand the subject any better. At least not the class I took. I made the mistake of researching the subject and reading the book before class and the only value of the class was a chance to use an O2...

In planning mode my nitrox computer and my NAUI (because that's what I have) nitrox tables come out about the same for a given mix. That is of course all square profile. I don't have real-world numbers for you but I suspect it's just like air...the computer benefit is credit for time not at...

One possible explanation: Tables are based on setting time from start of descent to start of ascent. So a 60' table dive will include some 0' time. That can safely be factored into the table and any sensible table compiler would. The computer times may be actual bottom time. So the 60'...

Here's my take.... 1) Like everything else, individuals are going to get out no more than they put in. If you sign up for a card you'll at best get a card. If you sign up for additional knowledge and experience you may get that too. If you sign up because an instructor didn't want to introduce...

I suspect the safety is about equal for new divers. DCS as a whole makes up a small part of the diving risk equation and new divers mitigate that risk successfully using either tool (and shallow dives/high SAC rates also help). The caveat is that using tables means remembering to mark start of...

The real dividing line on travel is flying (commercial). Airlines have weight charges and limits on what you can carry. That leads to light-weight and compact diving gear (which may compromise performance for packability). Traveling by car removes a lot of restrictions. Yes. Well, new to me. I...

My take is that it totally depends on four factors. 1) Do you have any long term goals that will influence your gear selection? (Travel, tech, etc.) 2) Can you afford to lose money on the gear? 3) Are you in an area where used gear is available/there is a market for used gear? 4) Do you have...

PADI seems to be absolutely mainstream regarding buoyancy control. I have looked at material from three agencies, five suit manufacturers, and a few other groups promoting dry suit usage. The vast majority say use your dry suit for buoyancy. They range from, "you should use the dry suit for...

Looking on the Saudi gov website, they don't mention the requirement. Looking on other websites several mention that women can own cars but are not allowed to drive in sa.
