    Gas Switching Methodology

    The thread is only a couple days old. Give it some time to fester properly. :D

    Taking PADI DM Course coming from NAUI

    DM is a leadership position, so much of what you learn in is how to supervise certified divers, assist instructors in classes, manage risk, and follow training standards. Although the "lower division" PADI manuals will not enlighten you any more than NAUI's, part of the learning that occurs...

    Snorting water like a cocaine addict

    I'm a nose breather; I admit it. You probably are, too. Blackwood's test is pretty much what I suggest to people. Try doing it with your regulator in, but add the following step: gently cover your nostrils with the pads of your fingertips (not pinch them shut) and inhale. You will probably...

    From rec to tec - a noob's reflections

    I don't disagree with you at all, and the only markings on my bottles are MOD, contents, and VIP (plus O2 label for the O2 bottle). I completely understand (and agree) that a banner doesn't tell you anything useful. No banners, colored regs, hose wraps, or neon signs to make sure the whole...

    From rec to tec - a noob's reflections

    Good write up. I found the classroom lectures in my class repetitive as well, and I wasn't overly impressed with the textbooks. But then again, I had studied two diving physiology texts and two of Bruce Wienke's books on decompression theory before I took the class, so I was accustomed to...

    Upside Down Diver!

    Before you get too upset about your trim, how "heads down" are you? Is your head only slightly lower than your fins, or are you standing upside down on your head? Do you have to tuck and roll because your torso is actually sinking, or is it because you feel that you're to far inclined? Since...

    PADI Sport Diver gear review

    Sport Diver is simply trying to be honest and accurate in its advertising. It uses the term "air cell" so that divers will not confuse the BCD in question with a BCD appropriate for use with nitrox (e.g. "nitrox cell") or trimix in technical diving (e.g. "trimix cell" or "TMx cell")...

    What's the best way to give rescue breaths w/a back inflating BCD?

    Your observations that deflating the BCD a bit and moving your weights around helped are spot on. Overinflation and weight position are probably what caused most of your problems. As for "mouth to snorkel," the snorkel creates additional "dead air" space and is harder to keep positioned...

    Can Suunto Cobra 2 be used for deco diving?

    Since every dive is a decompression dive, a Cobra will handle a decompression dive of the "no stop" variety just fine. However, dives requiring decompression stops are another matter. I do have experience with staged decompression diving and Suuntos. Here are the simple steps to follow for...

    San Carlos boats

    El Mar has a shop in San Carlos. Pricing for trips on the Piesquita are posted on the website. I *think* I heard that Gene bought a panga several months back, but I don't know if the panga is running dive trips or not.

    Any news on Oasis?

    Scuba Magic occupies the former Oasis (Tempe) location. Scuba Magic's owner negotiated a new lease with the landlord, obtained new vendor contracts, and purchased some of Oasis' assets. It does not appear that Scuba Magic's owner was an officer or director of Arizona Aquatic Adventures...

    To Rescue, or not to Rescue - that is the question.

    Torti was a hard case for appellate review. No matter how the court ruled, an undesirable result was guaranteed. As the saying goes, "hard cases make bad law." That is certainly evident in Torti. I agree with the dissenting justice's opinion filed in the case. The dissent did not believe...

    Weekday diving

    Who all is doing weekday dives? I've pretty much given up on weekends (except the extremely rare case), as I have to combat soccer, little league, and NDS Syndrome. Weekdays (daytime) are more flexible, and I need to log some bottom time.

    SLM / SAC Question

    SAC = Surface Air Consumption. You can calculate it in cubic feet per minute or litres per minute, depending upon which unit you use for gas consumption calculations. So yes, 12.1 litres per minute is approximately .43 cubic feet per minute.

    Off Topic Jabber and Bull Session

    My X-Vision leaks like a sieve and fogs no matter how much I scrub it. I end up using my Scubapro Frameless. I haven't used the Oceanic, but a smaller mask will probably help you. Aqualung makes a tiny mask that is beastly expensive but clears with little puff. You might also look into a...

    PADI DM course physics summary?

    For the exams, you need to understand how to apply Archimedes' Principle, the General Gas Law, Dalton's Law, and Henry's Law to specific circumstances. You also need to understand when you do not have sufficient information to answer a given question. Analogies can help you understand what and...

    Any one have fundraising ideas for a dive club?

    Is this a club associated with a high school, or is it a private club? There are different considerations for each type of organization, the most important of which is liability. Assuming you can get over those hurdles, fundraising ideas include bake sales, auctions of donated goods and...

    Gas planning and the associated math - controversies over need and how to teach

    You should be burned at the stake with a fire fueled by the heretical writings from which you preach such doctrine. I am made physically ill to witness someone advocate such a sensible position. I do not believe that it is a large extension of knowledge presented in OW to include SAC...

    Stop Banging - Diving is supposed to be fun

    My brother bought one of the duck blasters and honked it frequently on our recent dives. We ignored him underwater and then mocked him during surface intervals. And then we made fun of his "elevator lever" BCD. Good times.

    Questions about Rocky Point

    The links don't seem to be working, John. And thanks for reminding me of the new liveaboard. Completely forgot about it even though we had a discussion on it.
