What is the MasterKey Diving Set?
The MasterKey Diving Set is a compact training tool for scuba divers –
consisting of 9 waterproof learning cards in credit card format,
bundled together like a keychain.
Each card covers a core diving topic –
from preparation and equipment checks to safe execution and post-dive routines.
In short:
It’s your visual cheat sheet for diving – durable, lightweight,
easy to understand, and always with you.
Perfect for beginners, returning divers, and dive instructors alike.
Why do you need MasterKey?
Imagine this...
You're standing at the water's edge, ready to dive in –
but your head is spinning with questions:
How exactly was the preparation again?
What do I need to check on my gear?
How does equalizing really work?
And what if something suddenly goes wrong underwater?
Whether you're just starting out with diving
or getting back into it after a break –
this is exactly where MasterKey Diving comes in.
What's behind the QR code?
And why is it so valuable?
On the back of the first MasterKey Diving card, you'll find a QR code
that takes you to a digital knowledge platform.
There you'll find:
In-depth content related to each topic.
More detailed explanations of how things work, why they’re important, and what to pay attention to.
Scientifically grounded background knowledge – clearly and understandably prepared.
Checklists to print, laminate, and tick off – ideal for training, courses, or review.
The QR code expands the set from a compact cheat sheet
into a comprehensive training system.
It allows you to explore topics independently, understand the content more deeply,
and prepare even more effectively –
whether you're a student, beginner, returning diver, or instructor.
Important:
MasterKey Diving is not a substitute for dive training or a certified instructor.
It is a complementary learning tool that helps you better
understand key concepts, review them effectively, and apply them safely in practice –
always in conjunction with your training and under the guidance of a qualified instructor..

MasterKey Diving for Dive Instructors –
Your practical tool for clear and structured training
The set is far more than just a gimmick – it’s an effective visual teaching tool
that helps you make your training more structured, understandable, and practice-oriented.
Especially for beginners and returning divers, it’s a real gamechanger.
In theory, everything may seem clear –
but in practice, structure, guidance, and confidence are often missing.
That’s exactly where the set comes in:
with 9 waterproof cards covering all essential diving topics –
from the equipment check to post-dive procedures.
How to use it in class:
As a guiding thread for your course structure – one card at a time, a clear and structured roadmap
For briefings and debriefings – quick to explain, always at hand
To ease your teaching – fewer repetitions, more learner independence
Perfect for visual and hands-on learners
With QR codes for deeper insights – combining print and digital learning
Why use it in addition to books?
Because books are often missing when you need them most.
The set is compact, durable, and always within reach – clipped to your BCD and ready in the moment that matters.
It doesn’t replace anything – but adds value exactly where uncertainty arises: before the dive, in the water, and afterwards.
With MasterKey, you give your students:
Confidence through familiarity
Clarity through structured routines
Motivation through hands-on learning
You stay the pro –
MasterKey is your tool.
