I am considering buying some basic SCUBA equipment so that I can make a 'base' on the bottom of the sea so that I don't have to keep returning to the surface to breath. I don't really have much deep water near where I live so pretty much all my diving is in shallow water (only down to a maximum of about 10 metres). What I was thinking of doing is having a cylinder of air on the seabed at around 5 metres and returning to it whenever I run out of breath. Are there any safety issues concerning this? It's just an idea at the moment and I'd be interested to know if anybody does this or if you would advise against it.
Yes, there are some serious safety issues!

There are some pretty serious issues with this, and if you take a scuba-course you will find out. The most serious I beleive is that if you inhale fully at depth and then ascend, the air in your lungs will expand beyound your lung capacity. This can be fatal! There are other concerns as well with nitrogen in the blood etc (I guess you would have to follow scuba tables).

It's dangerous! Don't do it!

Ok, thanks, good advice. I'll just have to concentrate instead on getting my boat on the water!
