how deep can you dive?

It's called Martini's law. It basically says that each 33 or 50 feet (depending on who's version you use) is equal to drinking one dry martini on an empty stomach. Personally I wouldn't give this rule of thumb much value because narcosis affects each person differently. The best way to tell is do buddy-team narcosis tests to see how narked you are. For example, have a system that when one person shows x number of fingers, the buddy shows x-1, or whatever.

Excellent! Does this mean that if my Olympic-caliber liver and I can down 6 martinis and still walk & talk that we can dive to 300 feet??!??!

Come to think of it, I don't drink martinis. Is there Miller Lite's Law??

Somehow, your avatar seems strangely appropriate with this comment

Btw., how do you make your liver walk and talk? Now THERE's a neat party-trick....

My liver can walk, talk, beg (it does that a lot), roll over & (on a good day) fetch!

I'm going to say it depends on what you are taught. In my OW AND AOW there was nary a word said about proper dive planning and gas management. In my Deep class they went over those principles fairly well, though I still didn't totally get it.

So, I would say that if you don't know how to figure (properly) how long your dive is based on your depth and SCR (or SAC) and calculating in rock bottom (and how to compute that) then you shouldn't do the dive.

Well....I'll sell you a conversion table...

I have seen Rescue divers sink like a rock and land on the coral reef on their backsides. I've had friends with OW certs that have very good underwater skills and could easily go down deeper then 60 ft.

I believe in training for the type of diving you plan on doing, but obviously just taking the class doesn't mean a lot.

BTW, the idiot diver listed above was nicely scared by the reef (heard him talking about it in the hotel bar) and if I understand correctly spent the rest of his vacation diving the really bad/damaged reefs. (i.e., the DMs wouldn't let him near the good dives) Secondly, the reef he damaged was in pretty bad shape. I think it is the test reef, weed out the unexperienced divers. A form of damage control as I understand it.

Stay above (depth wise) a ppO2 of 1.4. You get used to narcosis but you never know when you may black out. (I've become much more conservative since joining this SB. Mainly because I got tired of being yelled at).

Then you have to look at the insurance side of things. If you have OW insurance and you have an accident after going deeper than you're qualified, are you going to be left with a hefty bill because the ins company says it is nullified?

surely whether or not you have insurance should never be a factor in deciding if you go deep? It's good to have it ( i have), but i wouldn't use it as a deciding factor..

I have to admit that I have found really good advice on SCUBA Board with the exception of this thread. I have to go back to the conservative advice and state dive according to your training, experience and what you are comfortable with.

It is too easy to get your self deep into trouble and don’t know it until it is too late. It is easy to go below your training limit. Most of the time you don’t feel any different if you exceed you limits. Nothing happened. 140 fsw is not much lower than 130 fsw. 100 fsw does not feel hardly any different than 60 fsw. But, your gas runs out faster, your NDL hits you sooner, Narcosis is a bigger player. It is also a longer distance up to free non-compressed air.

My advice, don’t exceed your limits educed by your lack of training, your health (emotional and physical), your experience, dive often. AOW is cheap, it is also easy.
