A couple of incidents on not-that-Deep Air persuaded me to seek trimix = training. I was lucky to have an excellent instructor (TDI, no less) who trained me= = without insisting on deep air practical stuff. Here, in the UK, most divers are BSAC, which frowns upon diving deeper = than 50 metres (167 fsw), but doesn't accept trimix at all. Ex-buddies = are diving on air in the 50m range and consider me dangerous for using = mixed gas. If they have an incident they usually either stop diving deep = for a while or stop diving at all. Most incidents aren't reported. If the current trends continue, the public who don't know the difference,= = will call for blanket regulation. I had intended to attach the text of an article in a well-respected = sunday paper as an example of the way things are going. Is it legal for = me to do that? In order to highlight the dangers of deep air to everyone, we have to win= = over the training bodies by reasoned argument. Some are receptive some = aren't, so there's a challenge. A deep dip in a chamber may just give people a taste of narcosis (first = fix) in a safe environment, so may not help. It didn't help me.
