Tech Tips: Nautilus Lifeline

Ok. You’ve probably seen advertisements for this thing – it’s Alec Peirce Scuba, by the way, with another tech tip – the Nautilus Lifeline. These are not new; they’ve been around for quite a while: a dozen years or maybe more. This is the newest version, which is by far the best. It’s completely automatic, it does everything, and you don’t...

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.

Tech Tips: Flex Hose or Swivel – Which is Best?

Hey guys, Alec Peirce Tech Tips here at Scuba 2000 in Toronto – beautiful dive store! This tech tip is from comments. Some people have asked me which works well: flex hose, swivels, or so-on. Let me tell you my opinion, and once again let me reiterate that I’m not telling you what to do. If it...

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.

Tech Tips: Portable Air Compressors Part I

Hi everyone, it’s Alec Peirce Scuba with tech tips again. This a neat tech tip for a couple of reasons. I haven’t spent a lot of time talking about compressors – I’ve covered a couple fill stations and so on – but quite a few divers (though not proportionately) own their own compressor. This is a tech tip about compressors, specifically...

Scuba Tech Tips: Nitrox – Good or Bad?

You’ve probably seen tanks like this: enriched air nitrox, EANX. Basically, that’s what nitrox is: it’s enriched air. What do you mean by enriched air? Simple. It’s air with more oxygen than normal.

Tech Tips: Make Your Own Hookah Surface Supply

Hi, guys, Alec Peirce from Alec Peirce Scuba and we’ve got a good one today! This is what’s called a hookah – a couple of you have asked about how to set up a surface supply. A hookah is just a fancy term to describe surface supply. By surface supply, I mean this: you’re underwater, breathing from a...

Alec Peirce Tech Tips: Proper Weight Balance

Alec and Helen

Hi guys, Alec Peirce Scuba here again at the AquaSub Scuba Diving Centre. I have one of our main instructors Helen here today to give me a hand in demonstrating weight deployment or weight placement. This comes up all the time: every time I mention weights or BCDs I get comments. I thought I’d quickly run through this with you.

Alec Peirce Tech Tips: Dry Suits Part II

Alec Peirce dry suits

We are once again into the drysuit diving season.  I want to share information you need to intelligently shop for a drysuit. I have already shared one drysuit video in which I showed you an old drysuit from the 1960s. It was made of thin rubber, that was basically a garbage bag to keep you dry. Think...

Alec Peirce Tech Tips: Servicing a Scuba Tank

We are talking about scuba tanks today; most folks believe that tanks are the most vital part of diving. Certainly, they are very important since it gives you the air you need to breathe. They can however, give you problems if not taken care of. Some folks do not own their tanks and instead rent them for about $15 a day. Others buy their own tanks and have to fill them for about $10 per dive. Divers who travel overseas generally rent them.
