The Chinese ban on air travel to Palau supposed has the hotels literally one half empty. Has this impacted the dive boats as well? (A lot of Chinese divers previously?)

"If it isn't stainless steel, it will rust." Bronze. No rust, no problem. Although, they're selling what are claimed to be small titanium carabiners (keyring size) on the web. If they really are titanium, that's puts both stainless and bronze to shame.

Reefrat- As long as you stay aware of your tanks' usage and condition, inside and out, there's nothing unreasonable. One could argue that for a recreational diver, one hydro per year is excessive, since tanks are built and tested for 100,000 uses, which is way beyond what one recreational diver...

Brian- In the larger world of commercial gasses and gas bottles? No one has to worry about salt water but no one uses plastic sleeves either. Your tanks are going to be used for EAN "forever" more or less? So, you do what commercial gas people do. PAINT the appropriate color code on the tank...

Well, GLOC, I would say that your story does not reflect on "who should make the choices" it reflects on the sometimes poor standards that some diving organizations set. Most commercial courses are run by dive shops, who only make money if everyone gets certified, everyone then needs to buy...

rh- Actually, yes, I am familiar with the Vega and the 2300cc engines. The larger story is that Chevy was tasked with building a small high performance engine, which they had never done before. And the Cosworth Vega proved it could be done, same base engine. What usually goes unsaid in the...

The OP's mistake is using the word "stronger". There are many different "strengths". In engine blocks, aluminum corrodes more easily and the engine coolant often must have extra corrosion inhibitors to compensate. On top of that, the cylinder walls need to resist "scuffing" abrasion from the...

The only question of luck, is whether their supervisor has to document # of complaints before the union (whoever) will quietly allow the employee in question to be fired. The TSA routinely fires some 500 baggage handlers a year for theft. The number of "inspectors" that are fired, harder to...

Carriage rules for batteries differ to alkaline cells and lithium metal primary cells (like the CR2032) and differ AGAIN for lithium-ion cells, like the rechargeables in a dive light. I've never heard of someone confiscating retail alkaline batteries, it sounds like some bully in a cheap uniform...

Be very careful about soldering onto any kind of rechargeable battery, especially lithium. They are not meant to be soldered to, and you may cause an internal breakdown, resulting in simple failure, or fire. The "correct" process is to tack weld nickel battery strips onto them, the tiny flash of...

First off, if a magnet did some good, I'd invest in the rare earth magnets that are WAY more powerful than a cheap ceramic magnet. Of course that's a problem, by the time they get to be silver dollar size they can really bite at your flesh if you get in their way. But 3? 4? years ago I saw a...

Different venues find different ways to steal money instead of being honest and admitting they need to raise taxes.

Passport renewal has became a racket. For instance, last time I renewed I sent it in about six months before expiry, since no one wants to accept a passport with less than six months on it anyway. Do you think the new one might have come back dated for ten MORE years? Nope. They eat the...

Doesn't sound right but I don't know that suit brand, or what your gear might be doing to it. On the practical side you might ask the suit maker, sometimes seams are simply sewn badly. Give them the chance to step up. If that's no help, you can coat the seams with Aquaseal or a similar flexible...

"Same thing for Nitrox, do we really need a course and training to breath gas with a higher 02 content?" Here is your tables, here is your dive. It really is immaterial what gas mix I am using, or what the numbers on those tables are, as long as I understand how to select and run the correct...

Scop has a long list of serious side effects. In the UK and former colonies you can still buy it OTC under brand names like Kwells, about $5 for a dozen pills. And it is incredibly effective BUT anyone trying ti for the first time, should consult their doctor wrt heart, eye pressure, possible...

I'm from the old school, i.e. my C-card means "Just give the man some air and leave him alone." And I'm all for privacy. On the other hand, if I were IN BUSINESS in this litigious society? As an instructor I have to follow the standards of my organization, or my insurer probably will say a...

Try to take a DEEP breath, use whatever lung capacity you have to gain buoyancy. "Helicoptering" with your arms, sculling with your hands, should be perfectly acceptable. And we're also taught that in order to conserve energy in a real emergency, it is perfectly acceptable to take that deep...

Consider asking the manufacturer if you can't figure out the carrier base from the ingredient label. Mineral-based sun blocks are basically "goo" loaded with lots of powdered rocks. Whether that's titanium dioxide or chalk, it is still just powdered rocks and no enzyme product is likely to eat...

Gorilla glue is pretty much inflexible, not meant to move with rubber even if it bonds to it. I'd try something more like AquaSeal or one of the other urethan specialty adhesives that remains flexible after it sets up. The problem is your "rubber" mask may be any one of several elastomers, not...
