This article is an abridged version of an early chapter in Simon Pridmore’s history of the early days of technical diving, Technically Speaking—Talks on Technical Diving, Volume 1: Genesis and Exodus. The nitrox saga would end up as the subject of vitriolic debate and bitter division in the sport diving community for half a decade. This is its origin story.

Analysis and Reflection as Learning Tools

In my time, I have been head coach and assistant coach to pro, semi-pro and national league rugby teams as well as the Irish women's team. I have been a sports psychologist and an advisor on performance and setting performance environments in rugby, golf, motorcycle racing, rally driving and many other professional and Olympic sports. I am now a technical diving instructor as well. Why the mini-CV?

The Insidious Threat of Complacency

People commonly say that experienced divers should guard against complacency, but what does that mean? Some associate the idea of complacency with arrogance, carelessness or negligence, and reassure themselves that if character traits such as these do not apply to them, then they do not have to worry about being complacent. Simon Pridmore offers insights into this phenomenon and how to prevent it.

What Does It Take to Be a “Good Diver?” — Part One

You are chatting with a diving friend and the conversation turns to mutual acquaintances. “Do you know Bob and Carol?” your friend asks. “Oh yes, good divers!” you reply. We will usually refer to someone as a good diver when they are not around. We will rarely say it to their face. And it is something that we all rather hope people say about us behind our backs.

Turning Tek

Once considered an extreme activity reserved only for a fringe set of explorers and adventurers, technical diving has grown in popularity since the ‘90s and has become mainstream. However, technical diving is not for everyone. Aside from an advanced skill set, it also requires a certain mindset. How do you know if you have got it? Simon Pridmore offers insights into what makes a good technical diver.

Out of Control

Narcosis vortex
Narcosis is the biggest threat to a diver on an air dive to 60m (200ft).

In his Scuba book series, Simon Pridmore often tells tales of diving close calls or near misses. He tries to identify the key factors and suggest what the divers might have done differently to pre-empt or better deal with what happened. All the stories are true. Some he witnessed, some were recounted by friends, and others just crossed his radar screen at some point to be filed away for future sharing. This is one of the latter.

All the Trimmings: Tips to Improve Your Efficiency in Water with Good Trim

With good trim, divers are more efficient and can stay longer and safer underwater.

Trim is a misunderstood, and often poorly rectified, scuba skill. In our scuba journey, trim is something that we may or may not encounter or discuss, unless we get into technical diving or more advanced recreational diving. Francesco Cameli offers insight and advice in how to improve your trim and increase your efficiency in the water.
