Have you guys seen this video by Paul Nicklen, a National Geographic underwater photographer? Awesome stuff! Face-Off With a Deadly Predator - YouTube

So I've been wondering about this one. I do try to manage my gas properly so that I will never run the risk of going OOA and so far I have never. But is it perhaps worth simulating an OOA experience by diving on a nearly empty cylinder but making sure you take the necessary safety precautions...

I'm not sure I know how the mechanism of an air dump valve actually works. The reason I'm asking this is because my wife's BC is forever filled with water after a dive. We have very similar BCs. I have the TUSA Platina Evolution and she has the TUSA Selene. Apart from the bladder and the fit...

Hi all, I'm hoping that someone might be able to help me identify these two commensal shrimps that I've photographed this past weekend at Sodwana Bay, South Africa. I assumed them both to be some species of Periclimenes but I understand that this genus has been split into a numebr of different...

Greetings folks, A friend of mine, not on SB, asked me if I had any info for her on diving San Diego. Well, I don't. But I did think that I might turn to to the SB community and find out if you folks could perhaps point us in the right direction? When is a good time to dive San Diego? Where...

I can't imagine that there could be many other places in the world where you could dive in the middle of the winter with only a 5mm wetsuit and be welcomed by these the moment you do your backwards roll: Oceanic Blacktip Shark (Carcharhinus limbatus) and then get some of these when you get...

Do Suunto manufacture state of the art computers or not? I would like to believe so but why then would they dump such a steaming turd on us and label it Suunto DM4? I've been using a few different versions of their software so far but most recently DM3.1.0. I was happy with it but there are a...

On the Suunto D4, in the Dive mode there are 4 options - Air, Nitrox, Free and Off. Can someone tell me what the purpose of the "Off" option is? When the computer is in dive mode and you're not diving it will default back to Time mode after a while anyway. Is there a good reason why one would...

I'm not sure if this is the correct forum for this post as I'm not sure whether it really was a near miss and I'm not sure if I've learned a lesson. I hope the mods will move the thread if there is a better forum for it. So on Saturday my wife and I did a dive at the local quarry. It was...

So in another thread there was some talk of hand signals not having universal meaning and which could cause confusion so I thought I'd test mine quickly. These are the signals that we use most often and I thought they'd be universally understood but now I'm not so sure. I'm interested to know...

I'm so sorry if this question has been asked before but ever since the upgrade to SB I'm having a hard time navigating around the site and can't seem to find any info pertaining to this question. I used to be able to select which of the subfora of the SB Matrix I wanted visible when I click...

I'm putting this in Advanced Scuba Discussions so that the "flame free" rules of the Basic Discussions forum don't apply and you are welcome to call me a stupid *insert expletive* moron if you feel like it. When I decided to get certified of course I was faced with the choice of agencies. I...

I know, I know, this topic gets rehashed so often that many will probably not even open this message. Seeing as you have though, I'm hoping you can offer information on the following question. I am getting sick and tired of people telling me that they won't try out SCUBA diving because...

OK, I constantly have this "problem" while I'm testing software that I've developed so I thought I'd put it out to the SB fraternity and see what you come up with. I often need a number of names to use as test values in this system I'm developing. I need names that will clearly stand out from...

I'm not sure if this functionality exists but I, for one, would find it very useful. Is there a way that I can mark a certain thread so that it doesn't show up in my "New Posts" page? I can mark entire subforums (or is that subfora?) not to show up in my "New Posts" page which is very useful...

I think it was Walter who once made a comment along the lines of "Anyone can abort any dive at any time for any reason." I like it and I think it's a mantra all divers should dive by. That said, I'd be lying if I said that I've never pushed through with a dive that I should probably have...

OK so the stupid loophole is plugged. Let's hope the sharks get some reprieve now. Shark Conservation Act Becomes Law | Wired Science | Wired.com

OK, seriously, I am at wits end. I'm developing software and needed to design some graphics for the software. I am a developer and not a graphic designer. While I do have some graphic design skills it can sometimes be surprisingly difficult for a developer who thinks mostly in abstract concepts...

There are two scuba related dreams, both equally odd, which I've had more than once. I thought I'd share and invite you to share yours. #1 - The pleasant dream I'm diving around the buildings of my old school. That's right, all the buildings of the school is submerged in clear tropical water...
