I would think so because you can just open up the zipper(s) to allow water to flow through if you get warm. You're liable to find it quite uncomfortable to gear up in the heat, however, and it will take you longer for gearing up than it will take others, if you're diving in a group or off a...

Like @stuartv notes above, the amount of diving you do makes all the difference. If you dive several times daily for several days in a row, you can lose a little more core temp each time you go and may be feeling uncomfortable by the end of the week when you started out just fine. If you get...

I went with the mid-level plan for a long time but eventually upgraded because I've seen enough incidents (none that were my own, thankfully) to realize the S can HTF for anyone at any time, and if it ever HTF for me, I'd feel like an idiot for missing valuable coverage for the sake of saving a...

Cold. Getting very, very cold. Even in 82 degree water where most people aren't even wearing exposure protection at all. :(

I think skills practice on a safety stop (and elsewhere) is an excellent idea. As for regulator retrieval, even if you never experience losing a regulator for any reason, it's still good practice in terms of remaining very familiar with your gear, how it moves and feels, and what's it like to...

Here's another one to go with it, since I notice you're fairly new: those particulates are the secret to buoyancy control. It was only when I learned to notice them and keep an eye on them that I gained decent control of my place in the water column. You get instant feedback on every little...

1. Use a predive checklist. A written one. Every time. It's just so much easier and safer. 2. Don't dive with anyone, especially an insta-buddy, with whom you've had no opportunity to first discuss priorities and plan the dive. One of the worst dive experiences I ever had happened under these...

Here's what gave me a considerable boost in confidence: a pre-dawn dive. It was dark when we went in but I knew it wasn't going to last all that long. Because of that, I settled right down and enjoyed the dark part, as well as the wonder of being there to notice everything gradually becoming...

I check mine every few minutes, more often at depth, not so much because of greater gas usage as because of the possibility on walls of changing depth without realizing it. I don't track the time per se as much as noticing where I am relative to the features on the reef. As I note the changing...

It depends in part on your thermal tolerance (some people need more protection than others) but also on how much diving you intend to do. If you're just doing a dive or two a day, you can get by with less than if you're doing multiple dives daily which would cause a slow loss of core temp over...

I agree with you. I was speaking in more general terms and not specifically related to this thread, which I didn't clarify.

^^^^^^^This! I've never seen the sense of entitlement to details of someone else's personal tragedy that I see come up in the discussion of diving accidents and fatalities.

I get nervous at the idea of defining a level of exposure protection that will be appropriate for a given water temp unless you know the person who's asking very well, because individual needs vary so widely. Most of my diving, for example, has been done in Caribbean waters where others were...

Congratulations on the experience of a lifetime!

That's an issue of unrealistic expectations, not personal deficiency. I hope you allow yourself to go nice and slow with your progression in this sport so that you can enjoy it for many years. You just tried way too much, too soon, because you're too new to know any better. The last thing you...

It says I will live to be 100. I have no desire to live that long, but I do want to feel good and be healthy enough to keep doing what I want to for however long I'm here. From Facebook: Whole You Health

I've done some compelling reading lately--The China Study and How Not to Die--which have finally convinced me that the standard, meat-based Western diet is exposing all of us to unnecessary cardiac risk. We won't all succumb to it, but we all have arteries that could be healthier than they are...

I can only say that I use a swivel and can't tell you how many times I've been able to make myself comfortable by changing the hose angle by a few degrees this way or that way. Can't do that with an elbow.

Really nice bit of analysis there, John. Thank you for taking the time and posting your results. I'd never have guessed that it actually shakes out this way. That's the beauty of looking at actual evidence rather than assuming what seems compelling (of which I am guilty more often than I'd care...

My personal experience has been that my conventional BCD switches back and forth just fine. I've never noticed any issue at all in that regard. Nothing feels different, works differently, or has to be adjusted, ever. On the other hand, I tried a BP/W once and hated it. Not because there's...
