Gee, Sam, I didn't think it was my obligation to educate a million boaters. I'm not the one who mandated use of the flag. Or, do you think divers should walk around the docks and launch ramps in saffron robes and ask everyone with a boat "Have you read this book yet?" Educate them? Uh, yeah...

IIRC Zophran is an anti-emetic. That is, designed to stop the puking, which is a significant part of motion sickness but not enough to make a sick person "functional" again in all cases. I haven't heard of it being used by any government agency for the purpose, but then again, I haven't spoken...

John- Contacting Suunto by email usually results in a three week delay before there's a reply. (I haven't tried phoning them.) I cna tell you that their policy is very simple. If the compass is under warranty, send it in for warranty service. If the compass is out of warranty, you are SOL...

Charlie, there's something about the Suunto compass designs that is just crap. I used a cheap ($1.49) ball compass from an auto store for thirty years and it never froze or leaked, so Suunto is just doing something wrong. Electronic is not necessarily a cure, it will mean batteries, and it...

Guys, do check your local laws, sometimes the specific size and construction of the flag is different from "stuff that's sold on the web". Even within the US, a flag can be perfectly legal in 49 states and still illegal in Florida. Personally I'd like something about six feet square that...

Been through them all over the years. If you want objective information, mine the many NASA papers and studies on motion sickness. If a diver gets sick, OK, they're miserable. If an astronaut gets sick...oopsie, coupla hundred million in equipment and the entire crew may die, so NASA has spent a...

IIRC the percentage of divers that got bent from improper ascent rates, back in the 70's and 80's "following your smallest bubbles", is curiously the same as the rate found in today's divers relying on an expensive and unreliable mixture of electronics and seawater held apart by mere o-rings...

Jack's got a good idea. At least, that's the conventional way of dealing with fog and rain (on land) and silt and particulates in the water. You get the light source off-center from your eyes, and there's less light reflected back into your eyes, as opposed to directly back at the light. In...

The thread may be dead but the complains still come up. "The cost of PADI training materials is pretty reasonable I think. " The book is about $60 US in 2018. And I can tell you, it doesn't cost anything more than $5, maybe 10, to print and another buck apiece to ship them out. The bottom line...

Jet Blue, no scuba tanks? So, I can bring this honking huge industrial CO2 bottle because that's not scuba, right? Sigh.

Wow, down to 40 pages, that's well over a buck per page now.(G) At that rate they could put the material up on pay-per-view online and just save the rest of the trees entirely.

Shouldn't have to be a special checked item, if you can fit it in your checked luggage. And I'm sure you can pick up a piece of 1970's hard sided Samsonite for $5 at any thrift store, if you don't have something that will "hide" and protect the tank. Valve off, TSA regs printed out and...

John, my old instructor was a D-day frogman. His diving skills started at that level. And he mentioned that one day, he was very curious to see why his exhaust bubbles were going SIDEWAYS so he decided to follow them and see where they were going. Of course they were going UP not sideways and...

Just wondering, since there are so many different "editions" (dated by year, not by any other apparent versioning) for the PADI EAN course book, does anyone know if PADI has actually been making changes in the course material, or the tables they're using? Moving from 1.6 to 1.4 as the preferred...

Thanks, Landon. But I have "Alert preferences" set on my forum account, so if you say "Beetlejuice Beetlejuice Beetlejuice" three times fast, I get an alert notice, regardless of the @ sign. I don't know if using that sign would forcibly generate a notice if I hadn't set them....but if you have...

Doc- I don't understand why folks prefix a name with the @ symbol in web forums. It doesn't DO anything in conventional forums, does it? It certainly doesn't send any message to me. AFAIK that's what, only a function on Twitter?? I wouldn't have said "What companies..?" if I knew them. I have...

tbone- "nor would I buy a regulator that has a warranty based on dealer authorized service at x-intervals." I might buy it but just ignore the loss of the lifetime warranty, I don't need to pay for authorized annual meddling. But who offers what liftime warranty without that condition? Not...

If the bottom was made of small hard rocks, as opposed to sand, yes. The ring might stay on top of them but wave action would scoot it away unless it got stuck or wedged into something. If the bottom was rocky meaning there were large rocks--you couldn't get a metal detector close enough, you'd...

Short answer, because they are safer. Longer answer: NOAA and the USN actually require the use of a J-valve or similar devices for black water diving. If you've ever dove in the kind of murk where you literally can't see your hands in front of your mask, that's why they are still required...

I spoke to someone at XS Scuba about 2-3 months ago. XS are the folks making pricey new J valves mainly for the military market, although anyone can buy one. At quite a price. He confirmed that USD was now totally out of the J-valve business. You may be able to find shops that have parts...
