The Human Diver Project: “Counter-Errorism”

“To err is to be human”, as the old axiom goes. When coupled with an intense skill-based activity such as scuba diving, human error can make the difference between safety and injury; in many cases, between life and death. Recognizing human fallibility and how to meet and overcome these demands in the world of scuba is The Human Diver Project: an in-depth program developed by dive safety expert, author, and former British RAF (Royal Air Force) officer Gareth Lock.

Tech Tips: Does Your BCD Fill with Water?

This particular viewer asked, “My BCD fills with water. Is that normal?” Yeah. That’s normal. BCDs fill with water and that’s the way it is. Let me explain, first of all, why they fill with water; and secondly, if you’re getting a lot of water – maybe too much of it – maybe there’s something you can do about it.

Vintage Scuba: What is Your Regulator’s Name?

As you saw from the title, we’re talking about names of your regulator. I don’t know if you have a name for your regulator: a lot of the regulators I’ve owned over years, I’ve had names for them. I can’t repeat those names because this is in the public domain - I didn’t have any called “Love” or “Deary”. The reason they had names was because the regs from manufacturers often had names prior to about 1975. They don’t today. If you have an APEKS XT-4 that’s not a name: that’s a brand or a model number. An Aqualung D200: that’s not a name.
