Going through this scenario, the first intention would be to try to ascend under your own power and abort the dive. If you can't physically maintain a consistent ascent with full kit (ie you start yo-yo-ing), then do a partial weight drop. If you still can't maintain a consistent ascent then...

In the vintage days divers would use a surf mat (modern ones are sometimes called a surf rider) to haul their backpacks, spears, and sometimes even tanks past the Monterey, CA surf zones. It looks like your floating pool mat but made of canvas or something more durable. Or that yellow black mat...

I've seen some programs cut a wooden backboard in half or 2/3 of the usual length. You load the un-kitted victim in water and then use the backboard to leverage off the swim platform to drag the person onto the deck. Works from either water-line to a 2ft drop from deck; but to be universal you...

Yeah, what I dub " The Divemaster Suit" from ScubaPro ;P In all seriousness it was a smaller venue than previous years. Others have hit already on the "fancy" sea water powered light, the new modular fin by Indigo Industries that has very questionable innovations. Everything else was pretty...

The problem isn't the oring. The oring inside the LP hose is to help seal, not swivel. The swivel capability is from the nut itself. A lubed oring does help, but a dry oring in of itself will not cause it to bind completely either. Binding completely would be a indicator that the hose nut is...

Plastic face gauges seem more possible for a faceplate blowout than glass. Glass is held by a very sturdy brass rim. Plastic is often not and just inset and sealed with an oring. There should not be any pressure behind the faceplate normally unless the bourbon tube is compromised. Even then...

I'm not living in Monterey anymore so I don't know the weather conditions and therefore can't give a good guess. It can be a few days, to a week, to a month. The short answer is blooms depends on weather a lot. And like weather, it is a best guess to determine how long a bloom will last. The...

If your frame or build changed significantly enough that you were smaller in your drysuit, you might tend to be putting more air to get to comfortable fluff than if your body were bigger taking up more volume in said drysuit. The baggier a drysuit, the more I see getting folds and creases that...

Tried it on an intern before. They're kinda wobbly. Lots of Top Gun references were made.

The AGA is supposed to be tuned as a positive pressure full face mask, so you will always have air drafting in the mask. AGA's pull air across the lens then into your mouth pocket, so your eyes are going to be constantly breezed with dry air. The only possible solution without changing the mask...

The diver exhalation bubbles can have some effect to "push" you upward in depth. If in enough mass and impacting on the center of your chest, you'll feel like you've gained some positively buoyancy. Usually it's not enough to really throw you off, unless you already don't have a good handle of...

An entire alternative before giving your intended answer: Go with the forward lean and get comfortable floating with your belly parallel with your horizon, or 0 degree trim with the bottom. Otherwise if you looking to hover vertical try to lean back with your core, move your legs forward and...

At that temp 16C, you'll want a 3-5mm hood/hooded vest and 1-3mm gloves. Hoods & gloves adds a lot of warmth retention. I wouldn't recommend ever going above 3mm gloves unless you're diving below 10C. You can learn pretty good dexterity in 3mm, but once you go above you pretty much are relegated...

By curiosity since no one else has asked: 1) Does this shop overfill tanks by habit? 2) How hot was it outside that day? 3) How long did tanks sit in the car with the sun up? It is possible that the a higher pressure can extrude a wrong sized valve neck oring. I had an old coworkers's HP tank...

I would say practice at the bottom at the start of your dive. The hardest part will be maintaining buoyancy while blowing bubbles. If you know your skillset and comfort you can attempt it early in your career, but I see a lot of new divers over-blow and go negative. OR they take a deep breath...

I think there's plenty of oversight, but it's the customer's want for privacy that can prevent the notice from reaching them. We as customers often opt out of giving contact info to the LDS cashier and registering at the mfg website. For your reference, this is the same story as with recalls on...

Uh....guys you kill fungus with antifungals or fungicide, not antibacterial. Bacteria is killed by antibacterials. Fungi is killed by antifungals. Listerine contains alcohol which only works to dissolve mold/fungus, but doesn't kill it. It's a solvent, not a killer. So you will still have left...

I didn't catch his example as relevant until after he explained it in the follow up reply. Calling the air pull as "dry" after your usable psi in my original post was my lazy way of saying till you reach the point of having to pull air through the reg VS it feeding it to you. And it was taken...

200psi in an Al 80 is roughly 5cf. 135psi (before IP is reached) = 3.4cf Ok, so after doing the math, yeah a couple minutes of breathing at a passive SAC rate. Lazy generalizing got to me again. But you're working for that remaining 2.6cf remaining cf once it gets below IP. Again then assuming...

When you get to about 200psi, how many breaths or minutes do you get on the tank? And what size & what depth?
