Yeah Tom was very good in the pool, but had very little experience in deep diving. Then he hopped on a sled and shot down to 122m, which is an ideal recipe for extreme narcosis.

I forgot to add in the above list, hallucinations. I haven't had any, but I know Will has during his deep free imersion dives (no fins, pull down and up the line by hand. Easy but slow, takes ages).

It's a topic with lots of scope for argument, do a quick search on some of the other forums if your interested in seeing some "interesting" arguments as to why it's "fine" or "safe" according to some.. :roll:


Thats for real. I know I've done some dumb stuff along the way but you would have to be certifiable dude to do that sh**. No matter what anyone says 80m on a single is daft.
You know the speed of light. So what is the speed of dark?

I see what you mean. Guess I was going off the fact that there has been far less fatality with bounce dives to 80m, but I must also say, that this was probably widespread a few decades back when people did bounce dives to spot Wrecks. Now we have W.A.S.P !

So would you say that a dozen 30m dives at 1:00 bottom time each would be great, ok or still pushing it ???

A 1:00 dive to 30m pretty much means a 'touch & go', given we travel at about 1m/s most of the time and a spearo with bifins would normally be slower. Absolutely fine in my opinion - must be, because thousands of freedivers and spearos around the world do it all the time. I was surprised to hear Herbert got bent doing those dives though, I know I've done similar things myself without any problems.
