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.

Tech Tips: Portable Air Compressors Part II

So here we are at the backdoor of Roger’s air fill station. He carries a lot more here than just his air fill: tanks, scuba gear, and his friends’ gear as well. It gives you an idea of the complexity. Here’s the problem: I mentioned earlier this is an ACFM compressor: you hook up your 80 cubic-foot tank and roughly 10 to 15 minutes later, one tank is full. That won’t work for us. We need four or five tanks filled at once. How do you do that? You obviously hook up more hoses.

Vintage Scuba: The Horse Collar (Mae West) Vest

Vests in the early days – for a long time, in fact, up until the ‘80s – had another feature that was a carry over from the Air Force/Navy vest. They had a CO2 cartridge, and in an emergency, you pulled on this and it blew the vest up instantly but only on the surface: if you did this underwater, one of two things would happen: if you were shallow, it would blow up and yank you to the surface quickly; if you were very deep, 60 feet or more, nothing happened because the pressure in the water was greater than the cartridge.
