In theory, an expert diver should be writing this post. Logically, he or she could tell you what to expect, give you insider tips and prepare you for the challenge ahead. Of course, as a newly qualified diver, I have one advantage over the experts: I know first-hand just how hard it is for the nervous first-timer. I know what it’s like to almost back out of your first dive and to quit the course altogether. I also know how to get back on it.

Five months after my first attempt, I passed the PADI Open Water Diver course.

Here’s a step-by-step guide for fellow divers who are somewhat nervous ahead of the course. I cover the theory first and then the hard stuff: the confined water tests and the open water tests, touching on a few difficult points along the way.

The PADI Open Water Diver course is, by far, the world's most popular scuba certification course. Millions of people have started diving as certified PADI Open Water Divers. Learning to scuba dive requires both knowledge development (facts, principles, concepts) and dive skills (techniques, methods).

Choosing a course

All PADI courses comprise the following:

180 Open Water Diver Manual 1. Uses for a dive ﬂoat include (check all that apply): a. Assisting another diver. Supporting a dive ﬂag. Carrying accessories. To avoid entanglement with a line to your surface ﬂoat: a. Don’t use a line — let it drift in the general area. The PADI Open Water Diver course consists of 3 main portions: Knowledge Development, Confined Water Dives and Open Water Dives. You can either complete your knowledge development online with PADI eLearning (desktop, mobile or tablet) or in a classroom.

Knowledge development: theory work to help you understand the basic principles of scuba diving. This is reviewed in a final test in which you must score 75% or higher. If you fail, you can retake the test. See ‘PADI test questions’ below for more.
Confined water dives: this is usually done in a pool or shallow water in the sea with the aim of teaching you basic scuba skills. See ‘PADI confined water tests’ below for more.
Open water dives: you must complete four open water dives in which you demonstrate your skills. See ‘PADI open water tests’ below for more.

In choosing a course, firstly, make sure your dive centre is certified by PADI. There are centres all over the world that advertise the PADI Open Water Diver course but which aren’t actually certified. They will happily take your money and while you probably will learn to dive, you won’t be certified.

Secondly, if you’re a nervous diver, try to book a 4-day or even 5-day course. The intensive 3-day courses run through the practical tests very quickly with little time to coach weak swimmers. A longer course means more time for hand holding (which I needed – literally).

PADI test questions

You will find the practical side of diving much easier if you read through the theory first. Your dive centre will supply you with a book and a DVD comprising five different chapters. If you can confidently answer the tests within the chapters and the knowledge reviews at the end of each, you will likely pass the exam without difficulty.

Depending on your learning style, it is possible to blitz through chapters 1-3 on one night and 4-5 on the second. Naturally, if you have more time to play with, then feel free to split up the studying even further.

To prepare for the PADI test questions:

Go over the knowledge reviews
Practise with flash cards
Revise the dive signals
Practise all the above with the Open Water Diver Course Ebook (PDF, $2.99)

Tips:

For the ‘BWRAF’ check, substitute the clunky PADI acronym (‘Begin With Review And Friend’) for ‘Bruce Willis Ruins All Films’. It’s not true of course but it’s far easier to remember.
For the five-point descent, use the SORTED acronym: Signal, Orientate, Regulator, Time, Equalise and Descend.
There is no standard acronym for the different types of ascents (Normal ascent, Alternative air source ascent, Controlled emergency swimming ascent, Buddy breathing ascent, Buoyant emergency ascent), but they will come up so use mine: NACBB for ‘Not All Children Break Bad’ – it’s far from perfect but it works for me!
Don’t be daunted by the dive tables. They seem complicated at first but are straightforward once you have been through the booklet. Check with your instructor if you will be using the manual tables or an electronic one. If the latter, you will only need a loose understanding of the former.

PADI confined water tests

The following is a list of the confined water tests (or ‘pool tests’) you will be expected to complete. According to my instructor, most nervous divers have difficulty clearing the mask (I certainly did!). If you have a snorkel and mask, practise this skill yourself before the course.

200 metre swim
Tread water for 10 minutes
Assemble, put on and adjust scuba gear
Pre-dive safety check (BWRAF)
Inflate and deflate BCD
Clear snorkel on ascent by exhaling sharply and continue breathing without lifting face from water
Swap from regulator to snorkel, snorkel to regulator several times without lifting face from water
Descend underwater (SORTED)
Clear water from your regulator (exhaling sharply and using purge button)
Use your SPG and signal your remaining air
Recover your regulator from behind your shoulder
Recognise and respond to hand signals underwater
Clear a partially flooded mask
Clear a fully flooded mask
Remove mask and breathe for one minute while stationary, replace and clear mask
Remove mask and swim for at least 15 metres, replace and clear mask
Breathe from a free-flowing regulator for 30 seconds (air blasts out of the regulator forcing you to ‘sip’ air from it)
Demonstrate neutral buoyancy: float at eye level at the surface with no or minimal air in the BCD and while holding a normal breath; pivot from horizontal to vertical underwater several times; float in the ‘Buddha’ stance for 30 seconds
Take off scuba gear and put it back on at surface and at depth
Tighten a loose cylinder band
Disconnect and reconnect the low pressure inflator at surface and at depth
Swim and navigate with a compass at surface and at depth
Remove and replace weights at surface and at depth
Emergency weight drop at surface and at depth
Cramp release on buddy and on yourself at surface and at depth
BCD oral inflation at surface and at depth
Out of air exercises: use alternate air source, provide alternate air source, practise buddy breathing for one minute while swimming
Practise a controlled emergency swimming ascent (CESA)
Ascend while equalising
Tired diver tow for 25 metres
Use inflatable signalling device
Remove weights, scuba unit and fins in water too deep in which to stand and exit
Post-dive care of scuba gear

Phew.

PADI open water tests

You must complete four open water dives in order to pass the course. Dive 1 will orientate you, get you comfortable with the scuba gear and test a few of the above skills. Dives 2 and 3 will rigorously test the above skills while Dive 4 is usually a more relaxed affair allowing you to use and enjoy your newly developed skills.

Final word

The most important thing to remember is to keep breathing and never hold your breath. If you feel panic rising, just continue breathing. If you can’t think through your flooded mask, just keep breathing. If you want to shoot up to the top, just keep breathing.

The second most important thing is to practise, practise, practise beforehand. The more time you spend in the water, the more confident you will become.
