I see. So maybe they call it a bungee but it's really one hollow strand. Possibly silicon tubing, possibly some other sort. OK.... I'm not into sudden fin strap failures, so I'd go with real multi-stranded bungee cord or an SS spring. Bungee is more reliable in theory, but sort of like...

A bungee strap should never break in a single event. As it loses strands it will become weaker until it fails altogether but you should know it's happening well before that. A spring strap can fail, I suppose, but I have never seen one do that or even heard about it.

FWIW, DRIS put a new zipper in one of my CF200s. DUI put a zipper in the other one a few years before that when I was part of their discount program. I could not tell the difference in workmanship. Both were excellently done, so well you can't tell they're not the original zippers. Without...

After the 3rd repair, my 2nd Seiko dive watch retired from diving. It kept leaking. The third time I found one for what the repair would cost but I only wear it swimming. Two Shearwaters are plenty.

Don't hesitate to get a high-end used suit if it fits. New zipper and seals are inexpensive in comparison.

I'll dive until my doctor tells me to stop or it's not fun any more, whichever is first.

Hey! I resemble that remark!

Sorry it wasn't clear. The point I was trying to make is that any heating design that does not allow the power to be quickly, completely, and reliably disconnected without unzipping a dry suit is a bad one. If you get a hot spot you should be able to unplug the heated vest or undergarment or...

So first off, any system that you cannot unplug underwater is a failure. There's no good reason for a heated vest or suit to burn you, ever. I was routinely doing 1-2 hour dives in 40F water for a while. Heat vastly improves comfort on longer dives. But as observed above, you still need to...

I have never seen so many people get off the floor as fast as when a burst disc blew in a tank at a dive shop. It was upright on a tile floor and had the old-style burst disc holder that blew air at right angles to the axis of the tank. It fell over, of course, and then rolled until the air...

Yeah, but (a) it ain't just that one post; like I said, this misconception rises from the ashes over and over, like the Phoenix, no matter how many times it's refuted and (b) I type pretty fast so it doesn't take much time. Thanks for the helpful tip, though.

Wikipedia says the dam is 177'/54m high. Maybe someone tried to convert from feet to meters by multiplying rather than dividing? 300m is, um, "pretty deep" for scuba. That's well into JIM suit territory.

Sorry, but I just have to comment on this one statement. This is simply not the case, but it gets repeated over and over (and over) and carried forward from generation to generation as though it were Holy Writ. I have heard it from any number of divers, instructors, and dive shop owners; but...

I'd plan on new seals and perhaps gloves. You can only hope the owner treated the zipper well. Other than that, crushed neoprene is (a) very tough, (b) ages very well, and (c) is very easy to seal up if it gets a small hole in it--a little dab of glue and it's usually good to go.

For sure. Also, I usually stay on O2 until I'm reaching for the ladder or reach shore*, whichever happens first. Either way, it's the most exertion I should have post-dive. * Except if the boat's gone, of course. I don't usually carry *that* much O2.

If you're on 100% O2 the off-gassing gradient cannot be improved by going any shallower than 20'.

Fair point. However, two people I'd dive with any time speak very highly of Jill as an instructor. Based on their recommendations I'd take instruction from her without a second thought.

I once shocked a local pool company that was using random people on scuba to do underwater inspections and repairs who had no training by telling them those people were at serious risk of dying and why. They were just uninformed, and they're good people. They started to use certified divers...

I was the *only* one to sit out a night dive when thunderstorms were forecast out of our group of 20+ divers. I was disappointed. I had good lights and diving in the dark isn't scary. But it was worth it to watch the mad scramble out of the water and up the hill when the storm hit 30 minutes...
