    HP Hose Failure

    {Edited by Mod} I'm still waiting for some figures and studies to back up your contentions.

    HP Hose Failure

    Big words that are not backed up by numbers. What studies are you relying on to make such assertions? It seems that you see your perceptions as "truth", and then demean all other opinions as somehow being "less". Still, you haven't produced a single statistic to back your opinions up. How many...

    HP Hose Failure

    You were wrong the first time you posted this. Sure, you want to sound superior, but the only one you're fooling is yourself. Fit and comfort are all about the diver's perception. It's the most important aspect in chosing my diving gear. Miflex had a 1% failure rate and they did a massive...

    Under weighted New Diver

    Almost all instructors overweight their students. I doubt you're any different. People who find that they are "suddenly" underweighted are usually undergoing some sort of panic episode.

    HP Hose Failure

    Many contemporary hoses have a very small tube in the center, with a thick jacket. Many hoses have a perforated outer jacket to avoid aneurisms that can be painful when they burst. As a point of reference, the thinner hoses often use the same inner tube, with a much thinner woven outer core...

    Spray painting with SCUBA...

    I pulled up to an Aldi, couldn't find a quarter, so I went to Publix instead. I don't know why I don't have a quarter. I don't use cash, so maybe I should go buy something.

    Dealing with Dive Anxiety: How I Overcame My Fears and Fell in Love with Diving

    I've taught a number of people with diving stress. To a one, they were determined to push through their fears. Phobias are not rational. It takes patience on both ends, but it was always worth it. For them as well as me. When Jaws came out, I had been diving for 5 or 6 years. I was fanning sand...

    Where to get VIP stickers

    No need for apologies. It's why we don't close threads. People ask us to close threads all the time, but we usually won't. If it doesn't interest you: don't read it. No need to question the motives of those who do respond to them.

    Where to get VIP stickers

    In the not-too-distant past, before we learned to not drain tanks completely, divers did just that. Tanks that were not closed had the tendency to accumulate water inside, causing all kinds of corrosion. Ergo, we learned to return to the boat with 500 psi (forget about conservancy) as well as...
