I learnt to respect vertigo after the one and only time I experienced it, scallop diving here in NZ in my early days, only 16m tops. I made a huge cloud of silt (my last ever cloud of silt come to think of it!) and my buddy winked out of existence. I tried to find him for a minute, then while...

Holy sh1t, I naively assumed that anyone in that industry would automatically receive far better trauma cover than the life/trauma package I get as a desk-diving software developer. Even if the on-site chamber WASN'T available, should he have been given an extra dive without it? And sending...

Bugger :(

I think they meant that the physical quantity of CO at 45ppm in each breath at depth is equivalent to a breath of 720ppm gas on the surface cos you're breathing 16x as much at depth.

We knew what you meant Don, calling it a hurricane immediately gave the people who came to this forum to find out how this poor chap died a feel for the conditions. And The Guardian's "Storm Ciara hammers UK with hurricane-force winds and floods" headline confirms the force involved. Since I'm...

Yeah food for thought alright, sidemount levels you out without trying, no sklls required at all to look like superman, and every dive my head is in the same position as when you sit down and stare at the ceiling.,Hmmm....

Yeah that's the ONLY thing I don't like about sidemount, having tanks in line with your body is amazing for perfect balance at any angle and any attitude in the water, just the most incredible feeling, but then you blow up the balloon on your back at the surface... Yep, it pitches you forward...

I took Swimbody's comment as relating to heart disease, not obesity. Ancel Key's deceitful seven countries study was largely responsible for the US govt recommending that all Americans reduce fat and increase carbs to 55-60% of daily calories, and was accompanied by both a massive upsurge in...

I've learned a LOT from this old thread too. I've got no high-current experience but based on the way a dpv makes my second reg free-flow that'll now be the first thing I think of, followed closely by the possibility of losing my mask turning my head. I never considered the full implication of...

I'm writing this out of genuine concern so please move rather than delete it? I'd like to state my wish that should I die diving, I fully endorse investigation of my accident by qualified divers so that other lives may be saved by the lessons learnt, even if it means my loved ones have to...

I respect the one who swam for the boat not just for their effort, but their summary ; I keep thinking now that I live on my boat I could go down too and reel off from the anchor. I mean... it seems safe, as I type this at my desk... I can see how they might have thought this was okay, as bad...

Yup redundancy doesn't end with hardware, I try to always have at least two or more tanks, regs, line cutters, torches, and brains, and at least FOUR eyes and hands...a buddy is just a redundant 'me' for when I break down.

As supplied by Yamaha in the engine bay of my Japanese domestic market SC38 Salon Cruiser, so already a respected product in 1989!

Might that create a more dangerous surge every time someone turned it back on tho I wonder? Genuine question - all I know about electricity is that wires are full of conductive smoke and stop working when all the smokes has leaked out.

While you may be used to this design and accustomed to trusting it because it's legal and the operator was top notch - that's without question - and the track record of the basic design is good, some of us are simply looking at it objectively through fresh eyes and seeing it for the first time...

As the link in the footer of the post of the artist formerly known as NetDoc suggests, "dive and let dive". For some of us, 'excitement' is reason enough to be in the water - there's no 'right' reason to do a particular dive, nor a 'proper' one as long as we plan and execute it well, what...

Sounds like the entire galley level - the most common source of fires on boats (tho batteries seem likely in this case) yet the only place where smoke is NORMAL - was unoccupied, in which case I don't think the fire needed to be FAST, it may have had all the time in the world to grow because as...

I hope so too, especially if reports that one of them lost his girlfriend to the fire are true. When I read that, and that one broke an ankle, I figured the moment they discovered the fire and rushed to the entrance to below decks, there was literally nothing anyone could have done :( The...

Ditto with my Mares torch, the entire thing completely flooded with seawater from lens to 26650 battery, and when I started to unscrew the battery compartment cap later thickish brown water oozed out but everything was fine - no bulging or anything, cleaned up okay. By no means a guaranteed...

I keep meaning to put a bungee on my long-hose as well, I always breath off the tank with the short-hose and bungee on the bottom in case I tox or pass out, but a heart attack can happen at ANY depth, two bucks to keep your reg in your mouth seems like good value. Have to remember to actually do...
