I think TSandM probably had a good analysis of your situation. The lack of a visual reference can make you dizzy. I've experienced dizziness a few times, but in my case I think it was most likely caused by my ears not being both in the same state of pressure; in other words, one ear clearing...

Wow! It ain't the entry, it's the exit that gets you!

Heard about the quake in Japan and the Tsunami heading towards the US west coast. We hope everything is alright. Internet connection is slower in Culebra. We liked the diving here better than Vieques. And on our night snorkel last night we saw octopus, squid, stingray, lobster, a massive hermit...

Hi It's Soakedlontra here. I cannot remember my password so cannot long in as me so I am borrowing Sam's Scubaboard identity for now that I have some time to kill but not enough to go snorkeling or scubadiving (waiting for the Publico to go to V ferry dock). The kayak tour of the mangrove...

Sorry, no photos yet, but we did two dives yesterday off Esperanza, south side of Vieques with Nan-Sea Charters. Saw a couple of big moray eels (great!) and five or six big lionfish (bad!). Our divemaster was named Chipper, and he said he knew (had met?) Bob and Susanne. Now we're off to...

One of my instructors introduced me to the concept of "Scuba Math". You round off, you extrapolate, you fudge, you give yourself a margin of error, and you don't spend a lot of effort calculating things out to eight decimal places because: No-Decompression Limits are not absolutes that can be...

Get an old toothbrush and keep your zipper clean. Dirt will destroy it faster than no lube will. You don't have to brush it every time, but you never know when some sand or something will get stuck in the wax, so it's a good idea to keep it handy. Most suit makers recommend against wax with...

Several people have mentioned viz. I understand that good viz gives you confidence, but it really has nothing to do with it, unless the viz is less than the distance you can go, and that's pretty rare. All good viz will do is give you a good view of the air you can't get to because you went too...

I'd like to hear the experiences of the people who've done this, in their own words. What was it like getting that stuff out of your lungs? What was it like taking that first "breath"? Did you ever get dizzy? Panicky? Out of breath? What was it like when you tried to talk? It sounds like more...

Don't forget to add the fact that you still have to get their attention and get their reg in your mouth. That could cut the distance in half. That's a good point, but the way I think about it, it's irrelevant. That's because I don't care whether you call it 15 feet or 10 feet, all I know is...

It appears we agree on what to do, just not whether to call it "an easy one" or "a considerable amount of work". Heck, for me, it's a considerable amount of work just to get out of bed in the morning.

String, I love you, man! Everything seems so simple and easy for you. My point is it takes a considerable amount of work to determine what the right distance is. My hammer is very safe until I pick it up and smash my finger with it. Thanks for beginning the discussion. This is one of those...

In my (not so) humble opinion, sending the suit back to DUI or having the LDS do the repair is totally up to the OP, and neither option is "silly". To you, the LDS found the problem and could have installed a new valve. To DUI, a customer has a leaky suit, and somebody who they may trust but...

I remember a TV show in the 60's when I was a kid; I don't remember the name of the program (21st Century? 2000 something?) but it was sponsored by Union Carbide. Do they still have TV ads? Anyway, I'll always remember a segment (maybe it was an ad?) showing a mouse in an aquarium, breathing...

Anybody have a source for Mares parts? I need a cover assembly for an older Abyss, but it looks like a newer one will fit, too.

Not at all! I think your ideas have merit. I was just saying that I don't expect the information to be offered without asking for it. This is true, but it is not without limit. What I mean is, we all benefit only if the standard we elevate to is useful. Adding extra burden and expense beyond...

This, along with your earlier post that said almost nobody asks for the info, says it all.

I used to ride a "slow" motorcycle, at least it was slow compared to some bikes. It was still way quicker than any car I could afford. Similarly, I chose a Suunto knowing it was conservative compared to other brands. I still get more bottom time than I did when I used the tables. I know have a...

I know how to make my Gekko more conservative, but not how to make it less conservative.

But safety is not concern number one; otherwise you wouldn't even leave home. Yes, we all want to manage the risks, but we have to remember that everyone is looking at this from a different angle. I'm not saying it isn't reasonable to ask about safety gear, training and procedures; of course...
