“Thank [beep] for that! How lucky were we? We better not do that again.
Don’t tell anyone though, we don’t want to look like amateurs...”

I started cave diving in Italy in 1990. At that time, the rules were very clear, codified and related to the kind of caves that were encountered in my region. Very often, they were resurgences with current (sometimes strong) or sumps inside caves, with water ranging from crystal clear to the color of coffee and variable visibility, depending on the rains.

I like sidemount. I will frequently, jokingly, disparage the configuration, but I do like it. It can be comfortable and streamlined. It can be very flexible. There is an argument to be made for completely isolated redundancy. Mostly, it is good for moving through places no bigger than the space below your coffee table.

“Wait, wait,” you may say when you read the title of this column, “What are you talking about? Aren’t those two things the same? Isn’t a dive instructor by definition a scuba professional? And what do you mean by ‘Road’?”
Training vs Experience

“Experience is what you get when you don't get what you want.” It is an old and well-worn phrase, but is it true?
Achieving Our Teaching Objectives
Diving instruction has standards, qualifications, materials, governing bodies and best practices. So why do we see such poor examples of diving practice? Why do so many new divers struggle with basic skills? Why do tech divers forget some key techniques? Is it poor instruction or something else?
The Swimming / Diving Disconnect
You must walk before you can run, so why do so few dive centres teach people how to swim before they learn to dive?
Personal Safety at Sea: Communicating with the Dive Boat

One of the things close to everyone’s thoughts is diver safety. We spend good money on quality dive gear and prudently have it frequently serviced and maintained, as this equipment will be sustaining our lives while underwater. But what about when we are on the surface? Just how many of us really do think about getting lost at sea?
Training Disabled Divers in Malaysia
The objective of the program is to build confidence, independence and self-esteem in the lives of children, adults and veterans with disabilities through the sport of scuba diving, scuba therapy and related activities.
The purpose of the program is to provide and support educational scuba diving programs with PADI courses—such as the PADI Seal Team, PADI Junior Open Water and the Open Water Diver course—that are open to any child, adult or veteran with a disability, with the hope of providing both physical and psychological therapeutic value to that person.

In 2006, a postgraduate program in maritime archaeology was established at the University of Southern Denmark. Based in Esbjerg, on the west coast of the Jutland Peninsula in southwestern Denmark, it is a one-of-a-kind university program in this centuries-old seafaring nation. The program is designed for students who want to pursue a professional career in maritime archaeology and heritage management.
