Its my first to go underwater with those diving equipment so its important to discuss it to my fellow colleagues for safety meeting minutes.. thank you for this video sir.
Very cool video. as a kid swimming, I always wanted to breath underwater. Thinking about taking up scuba diving as a new hobby. Seems kinda scary but fun once you learn how to use your equipment safely.
Thanks Paul. I'm going diving next week and appreciate the refresher. It's been a year so this video gives me a little confidence. I'll review again with the dive master.
Thank you for sharing!! ♥️♥️ Now you gave me more confidence! We are going to Maldives for our anniversary and we are planning to do scuba diving there! Wish us luck 🍀 😊
5 minutes of this Video, and I'm Hooked. Subscribed and all the stuff. I've been looking for quality information all around the internet. So far I'm delightful with your content and above all thrilled with your ability to communicate and explain everything.
See an ENT/otolaryngologist. Some people are born with issues with their eustachian tubes and a diagnosis and treatment might be in your future to correct the issue.
You should man! I got certified about 5 years ago, and it’s changed my life. Now I make over $200,000 a year, I’m happily married, I go on a lot of fun vacations… I feel smarter… own 3 rental homes for passive income… Diving has positively impacted my life in so many ways
It sounds cheesy, but scuba diving really has motivated me to earn more money and become better in business, sales and investing, in order to enjoy scuba diving, because it’s now my passion. It also motivates me to stay in good fitness shape and avoid bad stuff
Very informative, Thank you Paul. I'm watching all your videos before taking a PADI course to give me the basics ahead of time. I am concerned about the 3 dangers now though.
Thanks for watching. Well your instructor is there to help you build the right habits to keep you safe. But really it's all about slowing everything down. Zen

@@WaterlineShorts Hello, yes my scuba diving school is in Marseille South of France.... I do some english video with my strong french accent : ua-cam.com/video/4M-0zfs_U9Q/v-deo.html .... it will be a pleasure to make videos together ! Best regards :-)
I'm 34 and physically disabled and would like to lose some weight before putting myself through SCUBA training, in the long term the tank I'm gonna be diving in will only be between 7 and 10 ft deep. One thing I did wanna ask you Paul is how come most aquarium divers use smaller tanks with less air, given how big some of exhibits are wouldn't it be better to be safe than sorry with a larger tank and more air capacity.
Hi James. Sounds interesting. Many years ago I worked with a few different organisations that train divers with abilities ranging from blindness to quadriplegic. We would dive in lakes mostly and the ocean occasionally. This will be a slightly longwinded answer but its important to cover the bases so you understand rather than give a simple answer. Also, Im on metric so Ill leave you to do any conversions depending on what you use. At Rest: An adult has an approximate breathing rate of 6 Litres per minute at rest.

Tank volume assuming 200bar tank: 10L tank will hold 2000L of air. Assuming you leave at least 50 bar in at the end thats 1500L available to breath at 26L/minute = 57 minutes 7L tank 1400L: Leave 50 bar and use 150 Bar 1050L/26L/minute 40 minutes Most aquarium tank dives wont go past 30 minutes so even if youre new to diving and breathing more than an experienced diver you will have plenty of air in your tank at the end of a dive on a 7 Litre tank. I hope that makes sense. Sorry, youre gonna have to do some math to work it all out but I hope Ive given you the fundamentals to make the calculations. A smaller tank is perfectly reasonable.
Thank you i got most of this, im going for me first scuba diving course and i hope i do well. Im going about 10-20 meters is that ok for a person who hasn't done it before
Going diving tomorrow morning. I was certified last January in Bali and now I'm in Colombia about to do it again. Hasn't been quite a year, but I definitely wanted to watch a refresher. Thanks!
Hey Michael thanks for sharing. I’d love to dive in Bali. I’m not familiar with the diving in Colombia but I’m sure it’s better than the diving in the UK. Enjoy
This was great thank you so much I always wanted to go scuba diving and i thought because i could hold my breath for 2 minutes i would be good ...lol Guess not !!
When it comes to hokding your breath. How dangerous is it? For example I'd take a big breath, hold it just to accend a little and then breath normally again. I read just accending a few feet (not specifc enough for my liking) could rupture alveoli..
That's a good question. You need to use your breathing to control your buoyancy so you are on the right track. I would say that if you have to completely fill your lungs to get enough positive buoyancy to ascend a little then you probably have too much weight on your belt. If your lungs are completely inflated and you ascend in the top 10m/33ft while holding your breath you could rupture some alveoli, true. Possible but you need a very specific set of circumstances to line up so unlikely in just a few feet. Enough of a risk though to avoid the danger. Learning to control your buoyancy using your breathing is a balance between equipment, weight, time, depth and your breathing. Once time you get to know your limits better. Practice Taking longer deep breaths to ascend and if you get close toa full breath exhale quickly and then inhale slowly again.
Are you looking for gear to buy? Id say support local but honestly when it comes to gear I prefer shopping online. But then I know what I want and what sizes and most of the time my own gear I buy second hand. Like buying a car, many people get new gear and use it once or twice then dont use it for a year and sell it. You need to get a service to be sure but if you figure out what you want then you can get a good deal.
@@WaterlineShorts sorry I didn’t specify Yes I’m getting certified soon in Michigan And was looking for further insight in maybe finding used gear online instead of easily handing out $3k for dive equipment when I’m new to it as well.
@@kohlbyhasselman2265 Hey Kohlby So first off and this is the single most useful piece of advice I would encourage you to follow. Dont buy any gear. Or at least just buy your mask, snorkel, fins. This is the soft kit. These items you can use for diving and snorkelling and even if they sit in your garage for a few years, they dont cost that much and you can dust them off and take them on a family vacation. My first set was given to me by my dads friend who had them for 30 odd years. OK they were shit, made of rubber that was perishing and I got some new ones after I had some fun in the pool with them. But now Ive had one mask for 20 years and its still may favourite mask. As an instructor Ive had plenty over the years. The hard kit, BCD, Cylinder, Regulator even wetsuits or Drysuits possibly if you dive in Michigan are items you can hire anywhere you go. It will take you 20-30 dives to start to wrap your head around diving. In that time some people figure they just dont like it or they are happy to dive when they are on holiday or their dog dies and they just dont have the heart to go diving. Life happens. After 20-30 dives and you know you like it, youve dived with some different equipment and started to get an idea of the diving you like and the equipment you like. So honestly, I would say dont buy equipment just yet other than mask snorkel fins. Your dive centre will have equipment for your course and you can hire equipment wherever you go. I cant tell you how many times Ive bought good equipment for a low cost because someone started and bought everything only to not use it and sell it for less than they bought it. Rather spend a bit of money on going diving and enjoy yourself. Get to know what works for you. It will pay off in the long run. Or save you money if your dog dies. PS: If the dive centre told you you have to buy EVERYTHING for the course, find another dive centre.
I understand the not holding your breath while ascending or descending but if you are at a constant level with your lungs equalized why are you not allowed to hold your breath? Or why when you take out your regulator do you have to let out the small bubbles? Someone please help me understand that part. Thank you.
I've got a video coming out on Sunday and I answer that question in that video. Essentially it's two reasons. 1 it's good habit. You don't want to have one way at some times and another way at others. If you always blow bubbles when the reg is out your mouth then you don't have to think about it when it really matters. 2 if carbon dioxide builds up while you're holding your breath under water it has a bigger effect on you than at the surface. It will give you a headache and if you hold your breath long enough you will pass out. Quicker than at the surface.
I’m 10 youngest age for diving it gets really scary during lessons but when your dive master or instructor turns off you air is so just Incase it actually happens you know what to do
Hi I’m looking to start my open water certification. I’m curious as to what pieces of equipment should be purchased and which should be rented from dive center?
Great question. There are often two types of dive centres. With or without a shop. If they have a shop they will probably ask you to buy at least mask, snorkel, dive boots and fins. Often they will ask you to buy a wetsuit and weight belt but not always. They will never ask you to buy SCUBA gear ie BCD, regulator and cylinder. The price of your dive course will most likely include the rental of hard gear. Most resorts ie a diving destination that doesn't have a shop will probably have everything for you to rent so you don't have to buy anything and probably include that in the price of the course. I would say it's a good idea to buy your own mask, snorkel, fins and dive boots. These are items you can use to go snorkeling anywhere in the world, relatively inexpensive and they make a big difference to your comfort when you get used to them. A wetsuit is a great idea if you know the type of temperature of water you will dive in regularly but most resorts will rent you a wetsuit when you take a dive trip. Hope that helps. If you want to get started with your dive course for free there is a link in the description of this video. You can also use their app to find a dive centre near you. If you'd like more help I'm happy to get on a zoom call. Happy diving
If you have a good amount of money/good income (over $85k/a year) and you’re serious about scuba, then I recommend buying everything except for the tank. Tanks obviously you rent from where you’re diving
But if you’re not sure if you’re 100% serious about scuba yet- or, more likely, if you don’t have a ton of money- then I recommend buying the BCD, mask, snorkel, fins, boots, and dive watch, but renting the regulator, weights, wetsuit, and tank.
Basically, you always want to buy everything except for the regulator, weights, wetsuit, and tank. And if you have a lot of money, also buy your own regulator and wetsuit.
I do NOT recommend renting a BCD, because in an emergency, you need to be SUPER familiar with your BCD so you know exactly where your weights and your inflate/deflate valves are. In a split second, you need to be able to act. Trust me I know, over 150 dives
Some minor doubts: 1. what is the vertical bar near the left ear of the diver (looks like plastic and blue colour)? It's in the thumbnail. 2. Does the air pressure in the tank, as measured by the submersible gauge, (assuming, air has not been used by the diver), change at increasing depths of water?
Possibly. You would have to give it a go. Your local dive centres can do an intro dive in the pool. If you struggle there then you can discuss options with an instructor. Not expensive and you find out quickly.
Hey yeah for sure. You can get started for free with the theory side of things with Dive SSI. waterlineshop.com/divessi just create an account and start with the Open Water Course. Download the app too. This will help you find a local dive centre (closest to you) where you can do the pool dives.
What most USA people do is they plan a vacation to either the Bahamas, Florida, or Mexico, and then they get scuba certified while on vacation. If you’re new and just doing open water, I actually recommend PADI, not SSI. It’s more fun, engaging and thus you learn more
Don’t get me wrong, TDI and SSI is very good when you’re getting into technical diving, side mount diving, or cave diving (I dive full cave and sidemount, along with being advanced/rescue diver). But for basic Open Water & Advanced cert, PADI is best
Basically to put in a different way… SSI is so boring, and their courses are so clinical and scientific and factual, that most people will get bored just from reading it. You have to have already scuba dived, and already be passionate about diving, to actually enjoy reading SSI’s long winded and non-fun-sounding pages
I’ve dived with plenty big guys. There are two main areas you will consider. 1- The wetsuit you use will be larger and therefore have more buoyancy so you will take a bit more lead on your weight belt. 2- You will breath a bit more air so you will probably want to dive with a slightly larger tank. You should give it a go. You won’t regret it.
Yes it is. There are depth limits with your instructors will explain and there are certification restrictions which means a12 year old needs to have a professional in each dive. An adult can always dive with anyone else who is certified but a 12 year old needs to have professional supervision for safety.
@@WaterlineShorts Thank you for the response. I found a local dive shop here in Asheville NC that offers youth dive classes. Going to contact them tomorrow. Diving is a bucket list for me and my son is equally excited as well.
When diving you neutralise your buoyancy with your BCD or the jacket you wear. It inflates so that when you are under water you neither float nor sink. You hover. Then when you are ready to go up you start kicking and swim up slowly. There's more to it but that's the gist.
It’s really a combination of 1- don’t go too deep, 2- don’t stay down too long and 3- come up slowly. There are a few other factors like the concentration of oxygen in the air you breath but normally you just breath standard air like you do at the surface. There are Dive tables that tell you how long you can stay at certain depths to avoid it. You can watch my other video on decompression sickness for a more in depth explanation. ua-cam.com/video/r4ydTWo1Lm8/v-deo.html
@@WaterlineShorts Definitely will, I would rather be safe than sorry. D: I don't plan on doing any deep sea diving though, so I should be good. Probably 10-20m at most.
Wasted over $600 on Padi classes. Issued temp cards, but Padi corporate refuses to issue plastic cards. They referred me to legal. Then legal said she was authorized not to communicate anymore. Buyer beware!
Would love to know the story behind this. Have you been certified by the instructor and paid in full? Are they not issuing a plastic card but have registered your certification as a digital card?
@@WaterlineShorts I paid for everything and was issued both OWD and AOWD temp cards. I was told to mail it in for the real cards. I contacted Padi QA and complained about sexual harassment and poor quality training. Padi of America refuses to issue the real cards now because I complained. I posted a video about Johnny Director of Training of Padi promising to mail me the cards. I sent Padi a recording of sexual harassment from a Padi dive master too. The next day Padi's lawyer said no cards will be sent. And Padi's lawyer Stephanie sent me an email saying no further communication from Padi after I mentioned it didn't appear Johnny cared about the sexual harassment.
Padi Corporate won't issue plastic cards or digital cards to me after I complained to them about sexual harassment and poor training. All I have are the temporary cards that are good for 90 days issued by the dive center instructor.
I have 39 logged dives now, but Padi won't issue me any OWD or AOWD cards at all. The first 11 dives were from the OWD and AWOD class ran by 606722 and their dive center is SSI but I didn't know this as was told it was Padi dive center by the owner. But it doesn't matter as the owner was both SSI and Padi instructor. Dives 12-39 was with a different dive center. The different dive center is a Padi registered dive center and the dives were with Padi instructors. But Padi refuses to issue my cards after I complained about sexual harassment and poor quality training to their QA department. Johnny W. of Padi America promised the cards, but then Padi decided not to issue the next day.
You don't do that the people need to be with you or a school so they know what they are doing and so they don't mess up and get injuries from underbthe water and they need to do a test and go over scuba diving matarials you know what I'm saying
Oh yea and I'm jus saying cause I don't want anyone to get hurt I just want them to get used to an instructor and not ever dive alone number 1 never dive alone pls and ask an instructor for help
@@WaterlineShorts Glad to see this disclaimer, I've talked to way too many young people lately who believe they can watch a quick UA-cam video and buy some crap equipment off of Amazon, fill the tank with a bicycle pump or the tire hose at the gas station and they are suddenly Lloyd Bridges.
I understand what you are saying and I disagree. Scuba is dangerous. We mitigate against the risks through good practices and training but the risk exists. Hiking or backpacking has lower risks that even a lay person could avoid. Scuba has risks even for professionals. The example is not a good comparison.
I agree with both of you. Basically, once you get proper training, going scuba diving is less dangerous than other sports *as long as you do it right* . BUT if you don’t follow the rules, or act like an idiot, or get in over your head (forgive the pun haha), it can be deadly.
On the other hand, as a certified cave diver, cave diving is definitely more dangerous than other sports. It’s extremely fun and I except the risk because I love how beautiful and exciting it is. But I don’t buy into the delusion of thinking that it’s totally safe. I’m relying on lights to stay alive, and even though I bring 4 different lights, it’s always possible that they all die for some reason. It’s also possible the line gets lost or breaks somehow, or silt kicks up, or I somehow get lost… It’s also possible you can have a bad medical cramp or problem and not be able to get to the surface or be able to get out in time, with your limited air supply, because of a cramp… There’s a lot of possible problems. If you’re doing ocean, open water diving to a maximum of 130 feet or less, and you’re diving with a group, it’s very safe. One caveat is that if you’re diving a bottomless pit, such as over an ocean’s abyss or over a very deep place like Great Blue Hole which is 150 meters (470 feet) deep, then you need to have GREAT buoyancy/trim, know your BCD super well and have used it a lot before, and NOT be overweighted. This is because if you sink to the bottom accidentally, somehow, and the bottom is only like 150 or 160 feet or so, there’s a good chance you’re going to be rescued, somebody will help you gain buoyancy and y’all will come out alive. But if you sink to the bottom of something that’s like more than 200+, 300+ feet, you’re gonna die of oxygen toxicity, narcosis, pressure, gas/air running out, etc etc. And nobody is saving you. So be careful before diving over a deep abyss! You gotta know your stuff.
Put Another Dollar In.... PADI XD Better go french certifications if u r interested in good education and much cheaper course fees ;) And I am Boche, so no nationalistic falsehood XD
Your freaking gay and scuba diving is dangerous sport and you are putting yourself at risk of drowning or getting the bends or maybe having the risk of tissue damage in your. body
Although all information in this video is correct, you focus way too much on the 'dangers' of scuba diving. I think you scare off (potential) new divers. Yes: while scuba diving there are certain risks involved that you need to be aware off, but i think dangers is the wrong choice of words here.
Thanks for commenting. I think I understand what you mean. There are certain risks which are mitigated by information, skills and experience. I suppose I play a little to the audience much the same as a news station would hype a certain “danger”. But I am confident that the risks are dangerous if you don’t have the training. If that scares some people off, I don’t think that’s a bad thing. It’s not for everyone!

I'm 34 and physically disabled and would like to lose some weight before putting myself through SCUBA training, in the long term the tank I'm gonna be diving in will only be between 7 and 10 ft deep. One thing I did wanna ask you Paul is how come most aquarium divers use smaller tanks with less air, given how big some of exhibits are wouldn't it be better to be safe than sorry with a larger tank and more air capacity.
Hi James. Sounds interesting. Many years ago I worked with a few different organisations that train divers with abilities ranging from blindness to quadriplegic. We would dive in lakes mostly and the ocean occasionally.
This will be a slightly longwinded answer but its important to cover the bases so you understand rather than give a simple answer. Also, Im on metric so Ill leave you to do any conversions depending on what you use.
At Rest:
An adult has an approximate breathing rate of 6 Litres per minute at rest.
That breaks down as:
12 Breaths/minute
0.5L/breath
Under Exercise
Under exercise this goes up to around 90L/min.
30 Breaths
3L/Breath
So you can see that its not easy to give an exact answer but more to talk in general terms so you can work things out and get a better understanding.
Typical Dive
A typical dive for an experienced diver:
Depth 20meters deep
45 minutes
1500 Litres of air
This equates to 11L/minute equivalent to breathing at the surface (Let me know if you want a breakdown on the math)
A New diver:
Depth 20m
25 minute average
1500L of air
This equates to 20L/minute equivalent to breathing at the surface
OK so at a depth of 10ft which is 3m the atmospheric pressure will be 1.3bar so your typical rate of breathing will be 20L (for a new diver) x 1.3. = 26L of air per minute of equivalent air at the surface.
Tank volume assuming 200bar tank:
10L tank will hold 2000L of air. Assuming you leave at least 50 bar in at the end thats 1500L available to breath at 26L/minute = 57 minutes
7L tank 1400L: Leave 50 bar and use 150 Bar 1050L/26L/minute 40 minutes
Most aquarium tank dives wont go past 30 minutes so even if youre new to diving and breathing more than an experienced diver you will have plenty of air in your tank at the end of a dive on a 7 Litre tank.
I hope that makes sense. Sorry, youre gonna have to do some math to work it all out but I hope Ive given you the fundamentals to make the calculations.
A smaller tank is perfectly reasonable.
Thank you i got most of this, im going for me first scuba diving course and i hope i do well. Im going about 10-20 meters is that ok for a person who hasn't done it before
Yes thats what you should be doing for your open water course. Safe diving.

Yeah you should. It’s been such a big part of my life I can’t recommend it highly enough.
Thank you for sharing
👌
This was great thank you so much I always wanted to go scuba diving and i thought because i could hold my breath for 2 minutes i would be good ...lol Guess not !!
When it comes to hokding your breath. How dangerous is it? For example I'd take a big breath, hold it just to accend a little and then breath normally again.
I read just accending a few feet (not specifc enough for my liking) could rupture alveoli..
That's a good question. You need to use your breathing to control your buoyancy so you are on the right track.
I would say that if you have to completely fill your lungs to get enough positive buoyancy to ascend a little then you probably have too much weight on your belt.
If your lungs are completely inflated and you ascend in the top 10m/33ft while holding your breath you could rupture some alveoli, true. Possible but you need a very specific set of circumstances to line up so unlikely in just a few feet. Enough of a risk though to avoid the danger.
Learning to control your buoyancy using your breathing is a balance between equipment, weight, time, depth and your breathing. Once time you get to know your limits better. Practice Taking longer deep breaths to ascend and if you get close toa full breath exhale quickly and then inhale slowly again.
@@WaterlineShorts thanks for the great reply!
Just started diving after 22 years and intend to dive regularly from now on!
Great video and very insightful
Thanks. I hope it was helpful.
@@WaterlineShorts any places you recommend buying? Supporting I should say
Are you looking for gear to buy? Id say support local but honestly when it comes to gear I prefer shopping online. But then I know what I want and what sizes and most of the time my own gear I buy second hand. Like buying a car, many people get new gear and use it once or twice then dont use it for a year and sell it. You need to get a service to be sure but if you figure out what you want then you can get a good deal.
@@WaterlineShorts sorry I didn’t specify
Yes I’m getting certified soon in Michigan
And was looking for further insight in maybe finding used gear online instead of easily handing out $3k for dive equipment when I’m new to it as well.
@@kohlbyhasselman2265 Hey Kohlby
So first off and this is the single most useful piece of advice I would encourage you to follow. Dont buy any gear. Or at least just buy your mask, snorkel, fins.
This is the soft kit. These items you can use for diving and snorkelling and even if they sit in your garage for a few years, they dont cost that much and you can dust them off and take them on a family vacation. My first set was given to me by my dads friend who had them for 30 odd years. OK they were shit, made of rubber that was perishing and I got some new ones after I had some fun in the pool with them. But now Ive had one mask for 20 years and its still may favourite mask. As an instructor Ive had plenty over the years.
The hard kit, BCD, Cylinder, Regulator even wetsuits or Drysuits possibly if you dive in Michigan are items you can hire anywhere you go. It will take you 20-30 dives to start to wrap your head around diving. In that time some people figure they just dont like it or they are happy to dive when they are on holiday or their dog dies and they just dont have the heart to go diving. Life happens.
After 20-30 dives and you know you like it, youve dived with some different equipment and started to get an idea of the diving you like and the equipment you like. So honestly, I would say dont buy equipment just yet other than mask snorkel fins. Your dive centre will have equipment for your course and you can hire equipment wherever you go. I cant tell you how many times Ive bought good equipment for a low cost because someone started and bought everything only to not use it and sell it for less than they bought it.
Rather spend a bit of money on going diving and enjoy yourself. Get to know what works for you. It will pay off in the long run. Or save you money if your dog dies.
PS: If the dive centre told you you have to buy EVERYTHING for the course, find another dive centre.
Thanks
Thanks for watching
It looks so easy
John Seery I think it takes some practice and it becomes easier and easier.
I understand the not holding your breath while ascending or descending but if you are at a constant level with your lungs equalized why are you not allowed to hold your breath? Or why when you take out your regulator do you have to let out the small bubbles? Someone please help me understand that part. Thank you.
I've got a video coming out on Sunday and I answer that question in that video. Essentially it's two reasons. 1 it's good habit. You don't want to have one way at some times and another way at others. If you always blow bubbles when the reg is out your mouth then you don't have to think about it when it really matters. 2 if carbon dioxide builds up while you're holding your breath under water it has a bigger effect on you than at the surface. It will give you a headache and if you hold your breath long enough you will pass out. Quicker than at the surface.
I’m 10 youngest age for diving it gets really scary during lessons but when your dive master or instructor turns off you air is so just Incase it actually happens you know what to do
Yep I know what you mean. When you feel the air get tight and your heart starts bearing faster. Happens every time. Hope you enjoy your course.
where the fuck is 10 legal to scuba?
@@Robot50050 I read online that the lowest age you can scuba dive is 8
@@Robot50050 in our country its 8 HAHAHHAA
Hi I’m looking to start my open water certification. I’m curious as to what pieces of equipment should be purchased and which should be rented from dive center?
Great question. There are often two types of dive centres. With or without a shop. If they have a shop they will probably ask you to buy at least mask, snorkel, dive boots and fins. Often they will ask you to buy a wetsuit and weight belt but not always. They will never ask you to buy SCUBA gear ie BCD, regulator and cylinder. The price of your dive course will most likely include the rental of hard gear. Most resorts ie a diving destination that doesn't have a shop will probably have everything for you to rent so you don't have to buy anything and probably include that in the price of the course. I would say it's a good idea to buy your own mask, snorkel, fins and dive boots. These are items you can use to go snorkeling anywhere in the world, relatively inexpensive and they make a big difference to your comfort when you get used to them. A wetsuit is a great idea if you know the type of temperature of water you will dive in regularly but most resorts will rent you a wetsuit when you take a dive trip. Hope that helps. If you want to get started with your dive course for free there is a link in the description of this video. You can also use their app to find a dive centre near you. If you'd like more help I'm happy to get on a zoom call. Happy diving
If you have a good amount of money/good income (over $85k/a year) and you’re serious about scuba, then I recommend buying everything except for the tank. Tanks obviously you rent from where you’re diving
But if you’re not sure if you’re 100% serious about scuba yet- or, more likely, if you don’t have a ton of money- then I recommend buying the BCD, mask, snorkel, fins, boots, and dive watch, but renting the regulator, weights, wetsuit, and tank.
Basically, you always want to buy everything except for the regulator, weights, wetsuit, and tank. And if you have a lot of money, also buy your own regulator and wetsuit.
I do NOT recommend renting a BCD, because in an emergency, you need to be SUPER familiar with your BCD so you know exactly where your weights and your inflate/deflate valves are. In a split second, you need to be able to act. Trust me I know, over 150 dives
Many thanks. Clear and pretty comprehensive.
Some minor doubts:
1. what is the vertical bar near the left ear of the diver (looks like plastic and blue colour)? It's in the thumbnail.
2. Does the air pressure in the tank, as measured by the submersible gauge, (assuming, air has not been used by the diver), change at increasing depths of water?
Anybody go scuba diving after this?
That's very funny! I laughed out loud😂
Very informative
Thanks. Happy diving!
Dang it. I have always struggled with my sinuses and always have issues with my ears clearing. Wonder if that would keep me from being able to dive
Possibly. You would have to give it a go. Your local dive centres can do an intro dive in the pool. If you struggle there then you can discuss options with an instructor. Not expensive and you find out quickly.
Can I do scuba even I can’t swim into the deep water?
Thanks!
👍
Is there an online/zoom instruction course you recommend? I live in west TN, so I doubt there’s any classes I can physically take anywhere nearby.
Hey yeah for sure. You can get started for free with the theory side of things with Dive SSI. waterlineshop.com/divessi just create an account and start with the Open Water Course. Download the app too. This will help you find a local dive centre (closest to you) where you can do the pool dives.
Waterline Academy awesome! Thanks for the reply!
What most USA people do is they plan a vacation to either the Bahamas, Florida, or Mexico, and then they get scuba certified while on vacation. If you’re new and just doing open water, I actually recommend PADI, not SSI. It’s more fun, engaging and thus you learn more
Don’t get me wrong, TDI and SSI is very good when you’re getting into technical diving, side mount diving, or cave diving (I dive full cave and sidemount, along with being advanced/rescue diver). But for basic Open Water & Advanced cert, PADI is best
Basically to put in a different way… SSI is so boring, and their courses are so clinical and scientific and factual, that most people will get bored just from reading it. You have to have already scuba dived, and already be passionate about diving, to actually enjoy reading SSI’s long winded and non-fun-sounding pages
I’m a kinda big guy, does weigh effect scuba diving
I’ve dived with plenty big guys. There are two main areas you will consider.
1- The wetsuit you use will be larger and therefore have more buoyancy so you will take a bit more lead on your weight belt.
2- You will breath a bit more air so you will probably want to dive with a slightly larger tank.
You should give it a go. You won’t regret it.
@@WaterlineShorts I’m putting an anchor on my weight belt
@@nickferrari413 sounds like youve got it covered. lol
great video! I learned a lot. you earned my sub m8.👍
Thanks Jordan. I really appreciate that.
Play at .75 speed for clearer interpretation
Gotta love UA-cam for being able to change the speed of playback.
Duh you think?
Is it safe for kids to dive. 12 years old. I would like for me and my son to take a corse and learn to dive.
Yes it is. There are depth limits with your instructors will explain and there are certification restrictions which means a12 year old needs to have a professional in each dive. An adult can always dive with anyone else who is certified but a 12 year old needs to have professional supervision for safety.
@@WaterlineShorts Thank you for the response. I found a local dive shop here in Asheville NC that offers youth dive classes. Going to contact them tomorrow. Diving is a bucket list for me and my son is equally excited as well.
Fantastic. I hope you have a great time
So im ten and I know absolutely nothing about it and im terrified because the equipment is so heavy how do I go up when scuba diving
When diving you neutralise your buoyancy with your BCD or the jacket you wear. It inflates so that when you are under water you neither float nor sink. You hover. Then when you are ready to go up you start kicking and swim up slowly. There's more to it but that's the gist.
Thank you
How do you avoid the Bends?
It’s really a combination of 1- don’t go too deep, 2- don’t stay down too long and 3- come up slowly.
There are a few other factors like the concentration of oxygen in the air you breath but normally you just breath standard air like you do at the surface.
There are Dive tables that tell you how long you can stay at certain depths to avoid it.
You can watch my other video on decompression sickness for a more in depth explanation.

grenada cool
👍
Actually when you clear your mask you can just push down on the middle top part of the mask
My body weight is around 93 kg and also I don't know swimming. So is it possible for me to do scuba dive.
Your weight is no problem. You do need to be able to swim.
are you south african?
Yes
You have a South African accent
I am South African
I want to get certified so I can dive in the BVI (British Virgin Islands) in six months
Hope you are getting certified. Only two months till BVI.
Keep dreaming dude lol
Thanks now im scared
Ha ha. Happy diving
Hmmm, so as I ascend I need to void my lungs of air to match my depth? Yeah, I'm taking a diving class.
That’s right. Enjoy your course.
@@WaterlineShorts Definitely will, I would rather be safe than sorry. D: I don't plan on doing any deep sea diving though, so I should be good. Probably 10-20m at most.
That’s the best depth because you get the most light.
Wasted over $600 on Padi classes. Issued temp cards, but Padi corporate refuses to issue plastic cards. They referred me to legal. Then legal said she was authorized not to communicate anymore. Buyer beware!
Would love to know the story behind this. Have you been certified by the instructor and paid in full?
Are they not issuing a plastic card but have registered your certification as a digital card?
@@WaterlineShorts I paid for everything and was issued both OWD and AOWD temp cards. I was told to mail it in for the real cards. I contacted Padi QA and complained about sexual harassment and poor quality training. Padi of America refuses to issue the real cards now because I complained. I posted a video about Johnny Director of Training of Padi promising to mail me the cards. I sent Padi a recording of sexual harassment from a Padi dive master too. The next day Padi's lawyer said no cards will be sent. And Padi's lawyer Stephanie sent me an email saying no further communication from Padi after I mentioned it didn't appear Johnny cared about the sexual harassment.
Padi Corporate won't issue plastic cards or digital cards to me after I complained to them about sexual harassment and poor training. All I have are the temporary cards that are good for 90 days issued by the dive center instructor.
I have 39 logged dives now, but Padi won't issue me any OWD or AOWD cards at all. The first 11 dives were from the OWD and AWOD class ran by 606722 and their dive center is SSI but I didn't know this as was told it was Padi dive center by the owner. But it doesn't matter as the owner was both SSI and Padi instructor. Dives 12-39 was with a different dive center. The different dive center is a Padi registered dive center and the dives were with Padi instructors. But Padi refuses to issue my cards after I complained about sexual harassment and poor quality training to their QA department. Johnny W. of Padi America promised the cards, but then Padi decided not to issue the next day.
❤👍👌
horble but a little good
👍
You don't do that the people need to be with you or a school so they know what they are doing and so they don't mess up and get injuries from underbthe water and they need to do a test and go over scuba diving matarials you know what I'm saying
Oh yea and I'm jus saying cause I don't want anyone to get hurt I just want them to get used to an instructor and not ever dive alone number 1 never dive alone pls and ask an instructor for help
At 16 seconds, first thing I say is you need to get qualified at your local dive centre.
@@WaterlineShorts Glad to see this disclaimer, I've talked to way too many young people lately who believe they can watch a quick UA-cam video and buy some crap equipment off of Amazon, fill the tank with a bicycle pump or the tire hose at the gas station and they are suddenly Lloyd Bridges.
Not me here because I lost my phone at the bottom of a river
Call DallyMD
U makes it difficult 🤦🏻♂️
Not true , it was easy to understand.
Speaking too fast,
Ah yes. Someone else said the same. I’ll have to slow it down a bit.
I thought scuba diving was easier 😅
Ha ha. Thanks for watching
It's not
Please don’t call Scuba a “dangerous” sport. Statistically diving is less ‘dangerous’ than hiking or backpacking.
I understand what you are saying and I disagree. Scuba is dangerous. We mitigate against the risks through good practices and training but the risk exists.
Hiking or backpacking has lower risks that even a lay person could avoid. Scuba has risks even for professionals.
The example is not a good comparison.
I agree with both of you. Basically, once you get proper training, going scuba diving is less dangerous than other sports *as long as you do it right* . BUT if you don’t follow the rules, or act like an idiot, or get in over your head (forgive the pun haha), it can be deadly.
On the other hand, as a certified cave diver, cave diving is definitely more dangerous than other sports. It’s extremely fun and I except the risk because I love how beautiful and exciting it is. But I don’t buy into the delusion of thinking that it’s totally safe. I’m relying on lights to stay alive, and even though I bring 4 different lights, it’s always possible that they all die for some reason. It’s also possible the line gets lost or breaks somehow, or silt kicks up, or I somehow get lost… It’s also possible you can have a bad medical cramp or problem and not be able to get to the surface or be able to get out in time, with your limited air supply, because of a cramp… There’s a lot of possible problems.
If you’re doing ocean, open water diving to a maximum of 130 feet or less, and you’re diving with a group, it’s very safe.
One caveat is that if you’re diving a bottomless pit, such as over an ocean’s abyss or over a very deep place like Great Blue Hole which is 150 meters (470 feet) deep, then you need to have GREAT buoyancy/trim, know your BCD super well and have used it a lot before, and NOT be overweighted. This is because if you sink to the bottom accidentally, somehow, and the bottom is only like 150 or 160 feet or so, there’s a good chance you’re going to be rescued, somebody will help you gain buoyancy and y’all will come out alive. But if you sink to the bottom of something that’s like more than 200+, 300+ feet, you’re gonna die of oxygen toxicity, narcosis, pressure, gas/air running out, etc etc. And nobody is saving you. So be careful before diving over a deep abyss! You gotta know your stuff.
Scuba diving is dangerous and you are putting yourself at risk of drowning or getting the bends or possibly panicking underwater
Put Another Dollar In.... PADI XD Better go french certifications if u r interested in good education and much cheaper course fees ;) And I am Boche, so no nationalistic falsehood XD
Your freaking gay and scuba diving is dangerous sport and you are putting yourself at risk of drowning or getting the bends or maybe having the risk of tissue damage in your. body
Well thats just mean!
Although all information in this video is correct, you focus way too much on the 'dangers' of scuba diving. I think you scare off (potential) new divers.
Yes: while scuba diving there are certain risks involved that you need to be aware off, but i think dangers is the wrong choice of words here.
Thanks for commenting. I think I understand what you mean. There are certain risks which are mitigated by information, skills and experience.
I suppose I play a little to the audience much the same as a news station would hype a certain “danger”.
But I am confident that the risks are dangerous if you don’t have the training. If that scares some people off, I don’t think that’s a bad thing.
It’s not for everyone!
Thank you
