It's funny how different folks see things differently. My frame of reference is that I got my OW cert 28 days ago. So I'm hardly a highly experienced diver.... My first/only reg set is long hose/necklace alternate. That's what I've been diving from "dive 5" (where the first 4 are the OW cert...

Funny you should mention that. On pool day one I was asked to do the "trace the hose" method, and yes we were kneeling in the pool. Worse, we were in the shallow end so I was already feeling crowded by the concrete below, the surface above, and my general awkwardness in the gear (especially the...

I bet all of those were things the instructors could have failed the students for. That they didn't means either the instructor disagrees with your judgment about how dangerous those divers really are (very possible - some things look really dangerous to beginners, where more experienced eyes...

Something that gets missed in all of this is that sharks are delicious animals. One of the things I miss since moving away from coastal SoCal is the lack of fishermen who will kick me down free shark, yellowfin, etc.. :(

I found it interesting that the SDI/TDI instructor (actually his businesses card reads "instructor trainer" - whatever that means) I talked to said pretty much the same thing. He wanted me to be aware of both approaches and opined that ideally a diver would learn both, though which a diver used...

Because someone else quoted this..... Is that true? Says who? I did my PADI OW recently and there were several things called out as "must demonstrate to pass", starting with the swim test onward. I certainly didn't get the impression I could blow off a CESA demonstration and the instructor...

1) Blow into the oral inflator. 2) Looking at the picture, the low pressure hose conector is right next to the lever, which is on the left side of the BCD. Should be easy to disconnect if something sticks. Arguably easier than a normal inflator since it is always in the same place.

Out of curiosity, does anyone make BCDs without valve straps? I've used them on TUSA and ScubaPro. I'm pretty sure I've seen them on Zeagle and Oceanic. They don't really do much except make it easier to hang the BCD against the tank while doing up the tank strap(s) from what I've seen...

I've only used two types of tank... rented AL80s and my HP100. I like my HP100. I would (may) buy another. No plans to buy any aluminum cylinders, at least not in this size range. In practice it is more like a MP90 though. I have had my HP100 filled 10 times now and have never seen a final...

Oh that's easy. Both are real time physical skills which require the ability to perform complex tasks for extended periods without any hesitation or false steps. The main difference is that music is usually performed by a group which is perfectly synchronized in real time down to the finest...

I am interested. My current plan is to continue building skills with my diving and seek out training as I go to help refine and improve. I'm actually very frustrated with the badge (card) obsession in that my interest is purely in performance, not merit badges whether they are for AOW or GUE...

Yes, you do. Bluntly, that is a reflection of your assumption that disagreement = ignorance. Make people re-take the entire course when they just needed another 6 hours 1:1 refining one skill? That's a silly way to do things. And if gold was more common we wouldn't have such bulky weight...

Where does she say that? I read her statement as saying pass/fail is actually irrelevant. Nope. Either one is for badge collectors, if the goal is a badge. It's no different than the "bucket list" people or the BTDT people. There are people who climb Everest just to say they've done it...

Out of curiosity... Is there any reason to think pass/fail actually imparts more knowledge? To me pass/fail is just perpetuating the merit badge mind set. You pass this test you get a merit badge..err..card. Why? Because cards are...umm...expected in the scuba community. It all looks like...

Here's how I look at it...hopefully someone can correct me if I'm looking at it wrong.... Let's say you have a diver with a of volume 1. Doesn't matter what that is in cubic feet or meters, the diver is just "1 Diver" of volume. You put them in a drysuit with a volume slightly larger than the...

My OW instructor promulgated the "they'll grab the reg outta yer mouth" idea. He specifically trained that we were to grasp our alternate by the hose and interpose the reg between the OOA diver and our own mouth/reg so that if the OOA diver reached for the reg in our mouth they would find our...

So you take a long stride. Let's make this easy and say you have the watch on your fin and the drop is about 1m. In reality the watch would be higher up (and so moving faster by the time it reached the surface) but water drag starts slowing you at some point too. The watch is going to smack...

And while the distinction is incorrect (a shore is a shore), I too share that prejudice. The point about no real shore diving in Texas is well made when a website dedicated to shore diving lists basically nothing for Texas.

http://shorediving.com/Earth/USA_Mid/Texas/index.htm 8 locations listed for Texas, 7 of them fresh water, some of those dedicated scuba parks. That same website lists 97 shore diving sites for California, every one of them Pacific ocean.

From what I understand, the airlines have figured out that great mil pilots make mediocre airline pilots. Too many deeply ingrained habits (the product of much expensive training) that are inappropriate in the civilian context. The mil rout is still recommended for helicopters (where getting...
