I should have perhaps added more context. Currenly I'm not planning to switch to sidemount, this will be just a "fun thing to try out" during vacation. I'm not yet diving enough to justify changing over, buying a new set of regulators, BCD,... If/when that happens a new computer will also be in...

Hello, after *long* 10 years of no activity on this board and almost no diving! In the meanwhile I've had a kid, started riding a motorcycle, quit my job,.. and have started diving again. I like to learn and the resort where I'm going this October offers a sidemount course, which I intend to...

Did you actually read anything of the texts to which I provided the links (or indeed the whole post as opposed to parts of it)? If you did, I cannot see how you have failed to notice that in addition to Snopes I also provided links to two articles, one published in the American Journal of...

What do you base this statement on? If it's the old myth that you need to drink 8 glasses a day, it's just that: a myth. So please check out snopes.com: Eight Glasses of Water a Day for some facts concerning this. If you're up to some more advanced reading, try a meta study that can be read...

In my experience they are as dissimilar as two fins can be. Note that I am currently using paddle fins like these ones - slightly narrower and longer and quite lighter that the SP Jet Fins, but almost as stiff, so they can generate quite some force. I have tried TJM and SWN for two dives...

First of all, let me say that I have no connection to this incident, people involved,... and know just what has been written here. I also agree completely with DevonDiver's suspicions about sockpuppetness of the "Belgian Victim". Except with this one: A part of Belgium is Flemish speaking, a...

I would be very surprised if DIR wasn't big in Germany. After all it is very much in line with the traditional "Disziplin und Ordnung" mentality :D

I would certainly skip the safety stop in this situation. The very fact that you and your buddy got separated and that you are contemplating a return to surface mean that you have absolutely no idea what had happened with your buddy, so you cannot know that your buddy won't need assistance...

If this is titanium-nitride, it is a hell of a coating. I used to work in a laboratory that coated machine tooling (drill bits,...) with it. It hardens the surface, increases lifetime of tooling by factors, increases corrosion resistance,... And, unless the method of depositing it has changed...

An excellent source of information is The Rubicon Research Repository From one article (with a small sample of 4 people): and

As far as I understand this, I'd say that breathing a liquid solves most of the problems with various gasses in scuba, including HPNS. Breathing gas performs two functions: provides means of gas exchange (O2 into blood, CO2 from blood) and keeps the lungs inflated. In order to keep the lungs...

I suppose you have already decided on the design, but you might want to check out piezo switches. No movable parts and no magnets to confuse a compass.

Uhm, in the user manual for the Fusion it is stated that you store it with the zipper open, not closed. And yes, they say to pack it in the supplied bag.

Check out the article in DAN describing a workshop organised in 2000 and dedicated to reverse profiles. The conclusions are:

Unfortunately, you cannot sign up to "My PADI" at the moment. https://www.padi.com/padiprofile/html/comingsoon.asp

A few weeks ago I found a followup article in our major daily, Potaplja?a sta umrla zaradi kopice napak My comments about the translation are in {curly brackets}. ===== Divers died from a multitude of errors. The death of two Slovenian divers in an accident on the 25th July in the...

Indeed. Because your buddy is always within a few metres of you, checks you every few tens of seconds and there's not a single known incident where OOA prompted a rapid ascend and barotrauma, right?

Real divers don't need a stinking watch, they calculate time in water from estimated average depth, SAC and remaining tank pressure. ;)

David: I understand your reaction. No hard feelings :beerchug: I have a really good 15 page word document written by a pair of divers and researchers at our naval institute. And it's already in English so it just needs to be HTML-ified. I will write to them for permission to post the...

Sometimes the true intent of a post really gets lost in writing. Let me be very clear: it was not meant to ridicule anyone, it was a visual knee jerk reacion, so to say. Note that I have said a fancy dress party (not that I don't condone fetish parties). Since I've only started scuba...
