I've touched on weighting in other articles, but decided it was time I write something a little more in-depth on the subject. I really don’t know why I haven't started ranting about it in the past to be honest, as it's my personal bug bear.

You see, I have no idea how many people I taught or coached last year, but let's say it was 50, which sounds reasonable. Going through the list I can identify three people that I considered to be correctly weighted. Three. Of the people who were not correctly weighted, 100% of them were incorrectly weighted in terms of carrying too much lead. 100%.

At first this may not pique your interest, but please read it.  Even better download it, laminate it and put it in your dive kit. It could help save someone's life.

Of all the DIR subjects I get asked about, the one that demonstrates the most discussions seems to be ratio deco. I've written, somewhat extensively, in the past about how ratio deco is applied at the Tech 1 level; that is, for decompression dives between 30 metres and 48 metres.

Most people who are diving deeper than this know that a similar strategy can be applied when diving deeper. Tech 2 gives you so much more information that your certification card is limited by the depth you have been trained to, rather than any limitations in the tools you are given to plan deeper dives.

However, this is all well and good for the deep diving techie diver, but it’s not particularly useful for the shallow, recreational diver.  How we can make use of ratio deco at the recreational level, to make diving safer, or at the very least give us an extra tool to get out of the water safely.

Divers do seem to make life difficult for themselves, and I’ve never really understood why. How often have you looked around a boat and seen people with equipment they are struggling with, or are sweating with exertion, or are actively complaining about something. People seem to forget that diving is supposed to be fun. With a little foresight, it can also be easy. So let’s kick off with the obvious question - why do we care about pushing the easy button.

In 1911, two men set out to be the first to stand at the South Pole. One man succeeded. The other became a hero. 

The reputation of these men has waxed and waned over the following one hundred years. Scott has been at times a hero and at other times a buffoon. Amundsen has at times been the world's most respected explorer, and at others an egotistical maniac with thought of nothing but his own legacy. Whatever your thoughts on the men concerned it's difficult to deny that the story is epic and has lessons for modern explorers. I have read about the race for the pole for the last thirty years, indeed have a talk that I give to dive clubs on the subject, but only recently have looked it at from a perspective of diving. Make no mistake; we are all explorers when drop beneath the surface.
