That was the sort of explanation I was after. Agency age requirements aside, i was wondering what the difference between training a 14 yr old vs. 15 yr old. Physiological development makes sense.

O.K., O.K I am new to this website but I MUST comment on this THREAD. !st several of you shouldn't be giviing advice-period2nd to buy a computer or not to buy that is the question You need to look at what kind of diving youwill be doing repetitive diving, multi level on reefs just can;t beat the bottom time a computer will give you SAFELY Has any "Buddy" considered the ascent rate warning built into most computers if we look at DCS/DCI studies we're putting the brakes on ascent rates and a computer is GREAT way to monitor you ascent, how about the log mode Computers are becoming standard equipment which piece of gear you buy in which order should not be decided by how much it costs but how well it will improve your diving As far as getting "good" at tables, they all work the same AND you shouldn't be diving at all if you can't run a table without making a mistake EVER Keep your tables, stay profecient at them and buy a computer when you think you can utilize it best
1. SSI won't certify anyone to dive below 130 ft., much less a fourteen year old. If I were to lead such a dive (a fourteen year old to that depth, I mean), my DiveCon cert would be gone for good reason. Am I to assume that this was on air? That is a pretty good level of narcosis to expose yourself to. If I had a child (which I sort of do right now, my SO's children adore me), I would be more concerned about their safety than mine to begin with. Throw in a healthy bit of narcosis so neither one of you isn't thinking as clearly as normal. This could present a problem. But, I am glad the dive worked out and everybody had fun. In the end nobody was hurt. But many of the people on this board would NOT consider this a wise thing to try again.
2. My personal air consumption is such that I could easily violate tables and/or a computer if I didn't check them on repetitive dives. Many divers are like this. I used to run tables and still do when my multi-level numbers will give me a letter group. I do believe in tables. But for multi-level dives, I use my trusty dive computers. What I will not recommend is following the idea that "when I run out of gas I will come up and I don't need no steenkin' table or computer". On straight scuba air with repetitive dives it is exceedingly easy to violate decompression limits. I know of at least one case were the limits of both tables and computer were shattered on multiple dives. Nothing happened, but that was because the diver was fortunate. If you drive 120 miles per hour all the time, you will get into an accident eventually. If you choose to ignore tables and computers below fifty feet (especially if diving straight air), you will find yourself in serious trouble eventually.
My take, if you aren't sure what you want in a dive computer, wait. Once you know that you will be using a dive computer and for what kind of diving, get the one that you need. You can stay perfectly safe and learn with tables.

In theory no. I've seen 14 year old divers who were excellent in the water. The odd one even has a few years of diving experience and 100 dives already in shallower water. Obviously not every 14 year old has the composure and good judgement to dive that deep (narcosis). It also applies to divers much older than 14.
On the other hand, 140ft dives are something that you build up to and I wouldn't be allowed to do it as a DM. That should tell you something.
Anyway I just assumed the post was a troll so I ignored it.

[edit]
P.S. I'll just add to this that if the story is true that personally consider it unwise.
That's true. Seems to me that some digital bottom timers have that too.
And there are other ways to judge your ascent rate. I can think of 3 off the top of my head
- watch bubbles. If you're not the slowest thing going up in the water column it's too fast.
- watch a fixed reference point (floating stuff, the bottom, upline). If it's going past the length of your body faster than a 10 count on the way up then you're going too fast.
- watch your depth gauge and timepiece. If you're going up more than 2 metres every 10 seconds it's too fast.
In fact, I hardly ever use the ascent meter on my computer. It's so sensitive that almost any movement of my arm causes it to start flashing SLOW at me. My computer is a bit dated now but maybe the new ones are better in this respect.
I do the 10 count thing on a fixed reference and watch bubbles just the same way I was for the 15 years before I bought a computer (also years ago we used to count to 5
). Another interesting point about DCS is that as compared to the tables a computer will keep you under water longer. In theory that increases your risk of DCS. Perhaps even more so than learning how to make a controlled ascent without relying on your instruments.
Food for thought.

As I'll mostly be diving British waters multi level isn't such an issue & as for reefs!!!! What are they? lol :tease: So I'll rely on charts for now & probably go & get myself a computer next summer.
as for the 14 year old thing though I wouldn't like to comment cos I'm new & don't know enough but my gut feeling would be a question of "Would a childs lungs be developed enough to handle that kind of pressure?" now I know for a 10 year old or younger the answer would be no but as for a 14yr old... I'm not sure & I'd like proffesional opinion from a specialist :doctor: before entertaining such an idea. (infact I might start another thread :boom: )

I'm a dad with 2 little angels
Boy of 5 & a Girl of 7 & while I'd agree "She certainly couldn't have a more concientious partner." I would also admit that even though Dad's intentions would be right, Ignorance or misinformationi can mean that Dad dosn't always know best. This is why both my kids will be limited to snorkleing until they are much older. Just incase your wondering My 7 year old girl is a very good swimmer & wants more than anything to be a scuba diver when she's older.

Welcome to the sport, hope you enjoy your diving

I'm certainly not disagreeing that this would be a very bad idea in any event, but from a physiological standpoint, I'm curious about the effects of diving that deep that would be considered adverse (assuming that psychological and mental preparation is not an issue).
As the Young Diver Diving Deep etc. seemed to be kicking off I posted a thread in the Medical forum to get some input.

Those two Articles are well worth a read, then you can make up your own mind. I certainly learned something.

Yes, the diving part in general is a good thing, it's the particular dive I questioned. However, I feel compelled to point out that I didn't mention anything about a 14 year old _girl_. I simply said 14 year old. (BTW, I'm a woman. With a civil engineering degree. Hardly one to believe in "girls as girls" either.)
