No more 1/4 turns! (This has proven by professionals to not be the best way to leave your valve open.) Open your valve all the way to prevent any issues whilst diving! Other than that, great video for a refresher! Thank you!
Sorry dear am a professional, cmas course director, PADI instructor, Tec dive instructor, former army diver, owner of a diving center, certified over 5000 students including instructors. With over 20000 dives. Open your tank and close a 1/4 turn is the proper way. The only thing he has done wrong is purge the 2nd stage when opening the tank to avoid sudden high pressure to the piston of the 1st stage. Also inflate BCD and leave for something minutes to check if there's any puncture then test the lpi ( both ways 1st deflate with lpi push button then deflate by pulling lpi hope) inflate and deflate again. Inflate again and check both quick purge. Check all buckles. Breath in both 2nd stage and octopus to check they're working properly at the same time check the quality of the air in the tank. When you breath the spg needle must not move. If it moves it indicates that may be the spg in not ok or the tank isn't properly open or 1st stage problem
@@odeltarkhan3033 Most places have stopped teaching the back a 1/4 turn. I agree with everything else you said, but the the valve is very unlikely to stick if you open it all the way. What is more likely is confusion of a buddy diver on whether the valve is open or closed. Say for example a diver suddenly has problems with airflow, maybe they didn't open the valve fully etc, a fully open or full closed valve is an immediate indication to a buddy. If it doesn't turn one way the buddy knows it is either fully closed (thus causing the issue), or fully open and so the problem is something else. The 1/4 turn just adds confusion, that way the valve is floating between open and closed and the buddy might not know if they are opening or closing the valve. Each to their own, but this is like CPR, it gets updated every few years with new rules and guidance.
@@ciaranocallaghan5113 I agree with you mostly 1/4 turn was done to avoid confusion. In professional diving it was done to protect from freezing and to avoid damages when tangle in something like in cave diving, police or army rescue
Me watching this to remember which way the tank goes even though I’ve been on over 50 dives 👁👄👁 edit: the way I am a dive master now and people are still liking this comment is crazy 😭
It's always a good idea to wet the strap that holds the cylinder onto your BCD before assembly. These straps get softer and can stretch slightly once they're wet, especially if they dried with salt water not washed out properly from the previous dive. This demo has two straps but many BCDs only have one. Having the cylinder slide out of the strap a few minutes into the dive will upset your trim badly and may even pull the second stage out of your mouth.
@@Aidanhallbass Been diving for over 30 years with over 10,000 immersions. Have yet to find someone confused by the 1/4 turn and your claim it is dangerous is hyperbolic. There is no danger in a 1/4 turn back when the valve is already several rotations own. The reason you should not peg the valve all the way open it is the same reason you do not go 100% with most mechanical equipment, and that is having a margin of error for mechanical failure in the case of the unknown shit that can happen in the unforgiving environment that can be the salty sea. The other reason is that when it is pegged, it is hard to know which direction it is pegged (open or close) when the system is already charged. If the valve has give, you know the valve is open and is supplying air.
I think the "getting-in" clip is just decorational. There are a lot more things to be done before diving. Checking the diving place (first aid things locations etc), dive briefing, buddycheck,... For setting up your dive gear there is a more indepth procedure than this video shows. First your should try to breathe without pressure on it, to check the outgoing valves are sealing properly. Then open the valve while having the purge button on one breathing-thing (don't know English name) pressed in, once the air start coming out release the purge button. This is to prevent a big shock of pressure on all the equipment. Then you should smell te air to see if nothing is wrong with the air. Then you breathe through the primary and backup breathing-things. And check the gauge that the needle is not moving. I think they should take this video offline as it's misleading and a cause for dangerous situations due to being incomplete.
I did my diving license when I was 13 years old, and never dived since. Next weekend Ill have to do some dives so lets just hope I wont mess up too badly lol. I am planning to be an underwater referee for underwater rugby. So just pooldiving with a max depth of 5m.
On some of the newer valves, opening all the way is ok. In fact, some even have an indicator for valve position. However, older valves should be fully opened to turned clockwise about 1/4 turn.
If you need to do a valve drill underwater, and tern the valve 1/4 and it locks that means that it was on and that the other way is off. if you dont do that, you could think that because you cant tern the valve from the start, the tank must me off. making u accidentally close the tank valve. :/ Also i think it also has t do with the O-ring in the valve opening it all the way may have negative effects on that ring.
The 1/4 turn back was from the old pillar valves in the 1960s that would sometimes get stuck if they were left turned on "hard." But it's not only unnecessary with modern valves, it's actually dangerous and is no longer recommended, although many instructors still teach it because they don't know any better. "That's how we've always done it." How is it dangerous? Let's say you accidentally turn the valve the wrong way, turning it off, and then back 1/4 to just barely on. You take a test breath and you get air, and your pressure gauge shows full pressure, so down you go. Now you're down at 60 feet where you need a LOT of air with each breath, but your flow is restricted because your valve is only 1/4 open. Since 1/4-from-full-on feels the same as 1/4-from-full-off when you turn the handle, other than the direction you turn...DON'T DO IT! Turn it all the way on, or all the way off and you'll never have a problem. 100% open is now standard teaching from PADI, NAUI, SSI, DAN, etc. for a good reason. There is NO good reason to turn back 1/4.
Bad attachment of reg, the point of the yoke screw should be put into the dimple of the tank valve first then screwed up, this will cause the regulator to be pulled straight on to the "O" ring, seating it correctly ... this is basic scuba, and engineering !!!
Yeah you can talk because you aren't a diving center owner and have no Idea how many dumb divers try to open a tank that is already open and damage the tank valve. Then like a fool I have to empty the tank completely to repair the tank valve
Yeah how many people suffered from deco sickness or illness due to lack of knowledge????? Same as life diving evolve mate. Every time there's something new to increase diving safety. 40 years ago people were diving without octopus (spare regulatory) and diving with fenzy instead of BCD jacket. Suits were hard like rock but still couldn't keep you warm as required. Today suits are light and neoprene or plastic for dry suit

"Most people get certified when [they're] like 10." Nope. That's very young. Go to any scuba class that's not specific to kids and you'll see the average age is late teens to 20s. And that's just the average. In my class the youngest student was 13 and the oldest was 60.
