at 0:27 you can see her bubbles, she's in panic already. She doesn't spit the reg until 0:41, 14 seconds later. She likely had been in obvious panic before 0:27. All I can add, get to her sooner and calm her down, rescue diver grab her BC strap and look her in the eye. If she goes up fast...

"Hi, I'd like to go diving!" "Super, you'll need to fill out a form ." "I'll need a pen." "It's out on the buoy." "Where?" "Out there, 200 yards off the beach. In the ocean. The red one." "OK, be right back."

I had an OMS single bladder wing. Excellent quality. Dump valves, inflator hose, inflator assembly were all standard parts, DGX carried everything. Bladder Flange Tool | Dive Gear Express® With a bladder flange tool you could completely remove the bladder and replace / patch it yourself...

I think this sounds like an episode of Sea Hunt or Flipper.

I've seen Monk seals there. They work for the Division of Forestry and Wildlife and will turn you in if you mess with the wildlife.

Around here, if it snows a lot, the experts on local TV tell you not to shovel snow lest you get a heart attack. I haven't heard them say don't go diving. Out of all my friends, the fittest guy is also the stockiest. I think the best exercise for boat diving other than swimming would be...

This is kinda scuba as it's training related. If you are training yourself for an underwater swimming requirement, understand what shallow water blackout is. Dartmouth Swimmer Died Trying to Do 4 Laps Without Breathing This guy lived: Darren Harrity — Shallow Water Blackout Prevention Same...

Ask the airline about lithium-ion batteries in checked luggage. Kind of a common no-no.

I'd bet that in reality your body recovers from a lesser exposure to elevated PPO2 with a shorter "half life" than it recovers from an exposure that approaches a max limit.

Super on the progress! Just remember the underwater hand power stroke is like a butterfly hand power stroke, all the way to your hips. The inverted heart is for topwater breaststroke. Nothing beats pool time. If the Y isn't keen on you going underwater, you might sneak by doing your lap with...

One other thought on a frogkick. Your heels should come up to your butt, then the kick starts. If you bring your legs up really wrong, your legs will act like brakes and totally kill your momentum. Bringing your knees to your chest, or spreading your legs way out are examples of really wrong...

No scissor kicks, your hips stay level and the kick is symmetrical. I looked around youtube and this vid of kick seems about right. https://www.youtube.com/watch?v=BJj9z4n0STk But your arms are doing a long stroke all the way to your hips, not cut short like top water breast stroke arms. Get...

Don't ever look up, it's like dropping anchor. Figure out where you are by drain, marks, slope change etc. on the pool bottom. Stroke is underwater breast stroke. Streamline as much as possible, head down.. Recover your hands against your body where possible. Glide but don't stop. Giant...

I understand where you are coming from, but I don't think having the primary reg on a approx 32" hose is a bad idea for a recreational setup. No overhead, no caves, no penetrations. A rec diver who has air issues is probably not as well trained as a cave - wreck - tech diver. The OOA diver...

I would get a 22" hose and a bungee necklace and rig your octo (backup) on that. Breathe off your primary, if someone needs air they'll grab it out of your mouth or you donate that, then you breath off your backup, it's 4" away under your chin. Get 2 small bolt snaps, one for your primary...

Can you jump in the pool with just yourself, no gear? Exhale, you sink, right? Full breath, do you float?

I've pretty much given up on relying on stuff with batteries. If it's run by batteries, I have a non-electronic backup if at all possible. Yes to a watch & tables if the comp goes out. Yes to SPG. Seriously, I don't think a SPG is a step backward- https://www.divegearexpress.com/spg

This article was very sad to read, but it did have some information that really made me think about scuba and depth: Diver deaths result in changes to Navy Dive Manual, equipment | WTKR.com

What about hanging out at the surface? I kind of enjoy bobbing around with a mask and snorkel on. How can you put a full face mask on top of your head to give the "I'm really, really stressed, so I'm putting my mask on my forehead" signal? Seriously, this FFM thing would be really...

I would read Kwinter's post #33 again. And take the Dan o2 course or equivalent, or have an EMT show you how a medical kit works. Your victim may not be able to breathe off a regulator.
