Complete guide for new scuba divers on what to expect for your first dive.
So you want to learn to scuba dive? Great decision! Read this beginners guide to scuba diving to find out what certification is best for you, what the training involves, where to learn to dive, and some tips on what to expect when you first go scuba diving…

Learning to dive was one of the best decisions I have ever made. The time I spent getting certified was one of my happiest memories as it was then that I discovered the amazing world of diving. It also opened so many doors for me, allowed me to meet lots of like minded people and explore the underwater world.

However amazing, getting certified as a diver is also a big investment of money and time so you will want to understand your different options beforehand to make sure you choose the right one for you. It is also good to prepare yourself for what to expect when you first go scuba diving – as many things about it might surprise you!

It can be overwhelming when you first start looking in to scuba diving, with so many options out there for where to get certified, what agency, what course etc. I have tried to think of everything I can to help you prepare for your first time scuba diving and starting the best adventure ever.

 

What to expect when you first go diving?

Nothing can quite prepare you for your first diving experience but here are some of my key tips of what to expect as a beginner scuba diver…

  • You can’t just jump in the water and go diving. There will be a lot of theory in the classroom before you go in the water and start diving. You need to have some level of qualification to go diving, see your options below.
  • There is a lot of equipment, it’s pretty heavy and at first it might seem overwhelming but listen to your instructor carefully on how to set it up and take the time to understand your equipment and what it does before starting your dives
  • Breathing underwater feels weird – at first I remember feeling like I wasn’t getting enough air in, but you soon get used to it and eventually don’t even think about your breathing. You just have to trust in your equipment and if you ever start to feel panicked when you’re under the water just try and take in your surroundings and focus on that.
  • It’s amazing and so peaceful –  it’s so calm under the water with only the sound of your breathing in your regulator.
  • You will feel weightless. On the shore you will feel like the equipment is heavy and weighing you down, and will probably question how you will swim with all of it on your back, but you can actually move so freely and will feel very weightless when diving.
  • Seasickness – If you are prone to seasickness make sure you come prepared for your dive. The boat rides out to the dive sites can be long and often rocky so use whatever works for you to combat feeling nauseous, I personally just find staring at the horizon helps. Once you’re in the water you will feel fine!
  • You’re not alone – you will always have a dive buddy who will be within arms reach the whole time. Take the time to get to know them a bit before you jump in and make sure you are both clear on the hand gestures needed.

I also have some Dos and Don’ts for New Divers to help prepare you.

How do you learn to dive?

If you’re wanting to give scuba diving a try it’s unfortunately not as simple as grabbing a pair of fins, a tank and jumping in the sea.

You need to be qualified in order to be a scuba diver as there are some crucial safety protocols and information that you must be aware of before you can be classed as a diver.

There are a number of different qualifications on offer for you to choose from, whether you just want to see what it’s like or you want to commit to getting an open water certification. I have summarised some of the main ones on offer to new divers to help you figure out which one is best for you…

Discover Scuba Dive
If you only have one day on holiday to try out scuba diving many people use the Discover Scuba Dive Course, which can also be called a Try Dive. This involves a couple of hours of basic classroom safety training before going with a trained diver for one scuba dive, to a maximum depth of about 10m. I personally don’t think this is a great way to first experience scuba diving as it can be quite rushed trying to fit it all in one day. Diving and breathing underwater can be a new and strange feeling and it’s important to feel comfortable with the safety procedures, equipment, instructor and the sensation of breathing underwater before you go in to the ocean. In these discover/try dive courses there will also be a limit of how good your first dive can be with the restrictions on depth and duration. However, if you don’t have the time to complete the full Open Water certification, or if you just want a taster of what it feels like then this is your best option. Overall, I would suggest that if you can do your open water instead, opt for that course. Many dive centres will allow you to stop your course mid way if you don’t like it.
Open Water Diver
The most popular and common course for a beginner is the Open Water Diver. This certification will last the rest of your life and allows you to go for guided dives all over the world, up to18m. During the course you learn in detail about the safety tips, skills and equipment you need to be a scuba diver, take an exam to test your knowledge and gain diving experience with your instructor there to help. For more on what the course entails see the training section.
Advanced Open Water Diver
Many new divers will not stop at the Open Water certification and continue their learning by also getting their Advanced Open Water. This course is so much fun and I would highly recommend doing both! When I learnt to dive I only planned on doing the Open Water course but caught the diving bug and ended up changing my ongoing flight to stay longer and complete my Advanced. With Advanced Open Water you are certified to dive to 30m and gain some speciality skills such as night dives, wreck dives, deep diving and more. I talk more about what is involved in advance diver courses below.
Enriched Air (Nitrox)
This is another great addition to get under your certification belt as a newbie. Enriched Air certification is a speciality course that involves a different form of breathing gas which reduces the amount of nitrogen build up you get during dives. This allows you to stay down longer and have shorter surface intervals (so basically you can spend longer diving and less time in between dives). Only down side is that your maximum depth is less, however this wouldn’t effect you unless you were looking for some seriously deep dives.

PADI or SSI?

You will begin to notice that different places often offer courses from different scuba diving associations. The main two are PADI and SSI (and if you’re in the UK it’s British Sub Aqua Club, BSAC). PADI and SSI courses have a virtually identical course content and structure and and are both completely safe and trustworthy.  They are also interchangeable so if you get an SSI qualification this will be recognised in all PADI dive shops and vice versa. There is often a slight difference in the names of their courses (Eg. PADI Advanced vs SSI Advanced Adventurer). So there isn’t much difference between the two and you often will just use whichever one your dive school uses. PADI is more well known and prominent in most places, however SSI has a more flexible way of teaching students and has more advanced technology for online resources.

There is also BSAC (British Sub Aqua Club) if you are from the UK. BSAC Open Water course will also provide you with everything that PADI does but is known for giving more thorough training and a greater sense of community amongst other UK divers. This course does however take slightly longer than a PADI or SSI diver course.

What does the training entail?

When you begin learning to dive, the first couple of days will mainly be theory work, watching videos in a classroom and learning about important safety protocols.

The next stage is to get used to your equipment and the feeling of breathing underwater in a confined space such as a pool. You will do a few pool sessions where you start to learn your practical skills in a safe environment. Your practical skills are designed to prepare you for anything that could happen under the water and range from being able to clear your mask if it fills with water, to what to do in an emergency situation such as running out of air. These can seem tedious as they can take time but they are so important in feeling safe and comfortable when you start diving, knowing you are prepared for anything.

After your pool sessions you get to go for your first dive in the ocean! Even though you have already done some diving in a pool, being in the ocean feels completely different and sometimes can be scary if there is strong waves or because you can’t see the bottom. That’s why it’s important to take your time with the skills and feel comfortable before this step. 

 

It’s not all skills and studying when you are getting certified however, and you do have some open water dives where you get to enjoy the diving and take in your surroundings.

Before you can say you are officially a scuba diver you also do need to sit an exam to check you weren’t snoozing through the safety lessons – this is not too hard and reinforces everything you have learnt!

If you go on to your Advanced Open Water Diver course…

The advanced diver course is a lot of fun, there are no exams to sit and it’s only 2-3 days. In this course you get to learn lots of new skills that will make a big difference in your ability as a diver later on such as buoyancy control, navigation and deep diving. You also get to choose which adventure dives you would like to do, all of which are the first of a speciality course and include night diving, drift diving, wreck diving, underwater photography, fish ID, and search and recovery.

I chose to do night diving and wreck diving as two of mine and they were both incredible experiences – night diving is now one of my favourite kind of dives! 

Where can I learn to dive?

Where you learn to dive depends if you’re looking to do it near where you live or abroad on holiday but either way you can easily find your nearest certified dive centre. Make sure to read reviews on the school and do your research to choose a reputable company. Where you first learn to dive can have a big impact on you as a diver going forward so don’t take the decision lightly.

I learnt to dive in Thailand at Big Blue Dive School on Koh Tao and can’t recommend it enough.

How much does it cost?

The amount your diving certification will cost you will depend on which qualification you have chosen, where you are getting it done and what diving association you are with. In general diving certifications range from £50-100 for a discover scuba dive course to £200 – £600 for the open water or advanced certifications. However, once you are a certified diver you don’t have to pay as much later on if you want to go for more dives.

How long does it take?

Again this depends which course you choose and which association you dive with. Discover dives are done in one day, but to get certified Open Water it takes 4-7 days depending on how intense you want those days to be.

Is diving safe?

Scuba diving is actually quite a low-risk sport, especially if you follow all of your safety training and guidelines carefully.

This post by PADI goes in to more detail if you are concerned about the risks of diving.

Dos and Don’ts for first time divers

  • DO keep a dive log. Note down what marine life you saw, how deep you went and what weights you used so you can keep track of what you have done!
  • DO remember to equalize. Some people will struggle with the pressure on their ears a lot more than others so it’s important to not feel embarrassed if you can’t equalize straight away and take your time descending. Speak to your dive leader if you’re struggling to equalize.
  • DO stick with your dive buddy.
  • DO stay hydrated when diving. It’s very easy to forget to drink when you are on the boat for multiple dives, and in the sun.
  • DO listen to your dive briefing. You will be given a dive briefing before each dive – including what the layout of the dive will be, what marine life you might see, what underwater tests you will be doing, any important signals, make sure to listen.
  • DON’T dive hungover!
  • DON’T fly within 24 hours of diving. You will risk decompression sickness as your body hasn’t had time to get rid of any nitrogen build up.
  • DON’T use your arms. You don’t need to use your arms to propel forward when diving, it wastes energy you could be putting in to your massive fins.
  • DON’T touch the corals. It damages them!
  • DON’T bring single use plastic bottles. Help protect our oceans and get a reusable bottle.
  • DON’T forget your GoPro!
