To Shark Dive or Not to Shark Dive

It was seven in the morning and my coffee hadn’t kicked in yet. The dive guide was giving me a slightly more thorough dive briefing than normal. I wasn’t supposed to wear anything colorful or shiny, and black gloves and a hood were required. Also covered in black neoprene, he was putting on chainmail gloves and told me he’d have a pole with him. He said it was more for the potato cods though, not the sharks.

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.

Preconditioning for Safer Scuba Diving

This column is adapted from a chapter in my book, Scuba Physiological – Think you know all about Scuba Medicine? Think Again! The chapters in this book were originally written by scientists in the field of decompression research as part of a three-year project called PHYPODE (Physiology of Decompression). My (self-appointed) task was to rewrite their sometimes-complex research in a form accessible to all divers.

Beware of the Corner Cutters

Know that cheaper prices always involve corner cutting of some sort. Sometimes you can see it and it just involves the level of comfort or service. Sometimes you cannot see it and it may be prejudicial to your safety.

There are thousands of dive centres, resorts and liveaboards all over the world. Some are very good and provide excellent, safe and highly professional service. Others are not so good and are best avoided.

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.

The Barracuda Dive

Readers of my Scuba books often say how useful they find the stories I tell to illustrate key messages. The stories are all true. I wish I could say I made them up, but I am not that creative. Fortunately, life tends to be able to conjure up real situations that are far more instructive than those I could ever invent.
