DIGITAL LEARNING
diving, explains essential safety concepts, and builds the background knowledge you’ll need for each session. In addition, it includes your theory briefings, ensuring you feel well-prepared and confident before starting any in-water activities.
As the course progresses, your SSI Instructor will build on that foundation during each dive. This way, you’ll connect what you’ve learned online with practical, hands-on experience underwater. By completing most of the SSI Open Water Diver Digital Learning before you arrive, you’ll already have a solid understanding. As a result, you can focus entirely on developing your diving skills—both in the pool and out on the reef.
Furthermore, SSI’s cutting-edge digital learning system is one of the best in the world. It lets you study in the comfort of your home, at your own pace. You can even take notes directly in the app to review later with your instructor. After each section, you’ll complete short quizzes. You’ll need to answer correctly to move forward, which helps ensure you truly understand the material before you continue.
POOL TRAINING
Now it’s time to get wet—this is what you came for! We conduct confined water training for the Open Water Diver course in the swimming pool right at our dive base, making it easy and convenient to learn essential skills in a safe, controlled environment.
The pool session teaches you to use SCUBA safely and procedures to troubleshoot any problems you potentially might have. The swimming pool environment allows you a safe area to practice with no outside factors to worry about such as poor visibility, surge, or current.
This is about making sure you are comfortable using the scuba unit so our Instructors will make sure you have ample time to practice skills and perform them with ease before moving on to the next section of the course
OCEAN DIVES

Starting your professional scuba journey is exciting, but it’s important to plan it well. This Divemaster course schedule shows a structured 14-day training program designed to cover all the core workshops, academic sessions, and dive leadership requirements.
Completing the course in 14 days is possible, but it is not always ideal. We recommend spreading your Divemaster training over a longer period if you can. Taking extra time gives you more practice, more real-world dive leadership experience, and a stronger foundation for your professional career. As well as logging more dives. However, if you are prepared and committed, this schedule represents the minimum timeline to complete a full Divemaster training program.
Graduating as a Divemaster also requires meeting a critical milestone—you must log at least 60 dives before certification. If you are short on dives when you begin, you should plan extra dive days or enroll in one of our Divemaster career internships. These internships are the perfect way to boost your experience, log more dives, and polish your skills in real-world diving operations.
Following this schedule will prepare you to lead dives, assist instructors, and work confidently in the dive industry. But remember, quality experience matters. Taking extra time to refine your abilities can make all the difference as you step into your new role as a dive professional.
Now, let’s dive into the detailed Divemaster course schedule.

Are there Medical Conditions that Prevent You From Scuba Diving?
Can You Scuba Dive If You Have Asthma or Other Medical Conditions? Scuba diving opens the door to an incredible world beneath the surface. It’s peaceful, exciting, and unlike anything else. But if you have asthma or another medical condition, you might wonder if scuba diving is safe—or even possible.
The good news is that many people with medical conditions can still enjoy scuba diving. However, it depends on the specific condition, its severity, and how well it’s managed. Diving affects the body in unique ways, especially when it comes to pressure and breathing. That’s why medical clearance is so important.
But What About Asthma?
If you have asthma, diving isn’t automatically off the table. It depends on the type of asthma you have and what triggers it. For example, if your asthma is exercise-induced or worsens by cold air or stress, it may pose a higher risk underwater. But if it’s mild, well-controlled, and not triggered by diving conditions, many doctors will approve you to dive after a proper medical check.
How Does the Medical Screening Work?
Training agencies like SSI and PADI require you to complete a medical questionnaire before starting a course. If you answer “yes” to any condition—including asthma, diabetes, or heart issues—you’ll need to get a physician’s approval before diving. This is not just a formality. It’s a step that protects your safety and ensures you’re fit to dive under pressure. Download the medical form here.
Many divers with medical conditions dive safely every day. The key is honest communication, both with your doctor and your instructor. In some cases, a diving doctor may request further tests or recommend specific dive limits. With proper precautions, even those with chronic conditions can enjoy underwater experiences.
So, can you scuba dive with asthma or other medical issues? In many cases, yes. But you need to go through the right channels, get professional advice, and listen to your body. Always prioritize safety. When you do, you can turn your health limitations into manageable challenges—not barriers.
Scuba diving is for everyone who can dive safely, and with modern medicine and responsible training, that includes more people than ever before.

We are very excited to announce that we are offering the PADI Sidemount Diver course in Kenya at Ocean Tribe. From mid-December you will be able to be trained on sidemount, opening up a whole other side of diving for you. For the first program top PADI Sidemount Instructor Trainer, Platinum Course Director Gary Phillips will be travelling to Kenya to run the program.
What is Sidemount Diving
Normal scuba diving involves carrying a single cylinder on your back. This is back mount diving. Sidemount diving is simply a configuration where the tanks are arranged on your sides rather than your back. Sidemount diving can be used in sport, technical, and overhead environment diving and was originally developed by cave divers.
Sidemount divers often dive with two tanks attached in the water which can make gearing up easier. The tanks are attached to the diver’s harness with bungees or straps which can be easily removed or adjusted while diving.
In technical diving where multiple cylinders often have to be carried some believe that it is easier when using sidemount. You can move onto the PADI Tec Sidemount Diver course from the PADI Sidemount Course to learn how to mount at least 4 tanks for tech diving.
So why should you try sidemount diving? It is a new diving configuration so is it for you? Below are a few good reasons to become a sidemount diver.
Streamlining
As divers, it is very important to be as streamlined as possible. When we see marine creatures underwater, we marvel at the speed they travel. This is because their streamlining has developed over millions of years of evolution. So how do we match it?
The main problem is water is 800 times denser than air and not being streamlined can create drag which means you have to work harder to propel yourself, using more energy and your precious air. So even small things like having your feet slightly below the rest of your body can create significant drag requiring more effort to move.
What diving a sidemount configuration does is align the cylinders with your body and the direction of travel. This streamlining can make propulsion easier and your dive much more relaxed and comfortable.
Trim
Trim refers to the forward-to-back orientation of a diver and is usually referenced as; ‘in trim’, ‘head down’, or ‘feet down’. Getting the right trim is a basic diving requirement to move efficiently underwater. This is normally a good horizontal trim.
A good trim is achieved by having the correct weighting amount and positioning on your body, coupled with the correct positioning of gas in your BCD and dry suit (if you are wearing one).
While it is perfectly possible to get a great trim in back mount diving
(And also essential for good easy normal diving). Sidemount diving can make it easier due to the cylinder position at the sides of your body. This allows them to more closely align with your centres of gravity and buoyancy.
Balance
When you are diving with cylinders on your back, you have to use body tension to keep your balance when turning towards your sides. You often can feel unbalanced in these situations.
By contrast, when you are diving sidemount, the cylinders are mounted on either side of your chest and no matter what your orientation in the water, the centre of gravity is near the centre of your body and you are always balanced.
Stability
When you are stable when diving you can relax almost completely, whilst remaining with a good trim and balance. This makes you truly weightless and also a stable platform. From which you can perform tasks and skills in the same position in the water.
This can be incredibly important when doing some of the dives that sidemount is intended for such as overhead environments. You do not want to make contact with the floor of a wreck or cave and cause a silt out, or hurt yourself hitting overhead objects. Additionally, it is essential to be able to maintain good buoyancy for decompression stops and gas-switching tasks at specific depths, when using the configuration for tech diving.
I would just like to point out that good stability is perfectly achievable with backmount and many of us have achieved this with little difficulty. Some sidemount pros have pointed out that sidemount configurations can be easier to develop this skill in their opinions. See what you think.
Redundancy
One of the main benefits of sidemount is that enables you to carry more gas. It also provides you with a redundancy system in the event of equipment failure or diver error. This is a requirement for all technical diving. Sidemount can provide two independent gas supplies. While this has its pros and cons the redundancy feature of sidemount is a serious benefit.
Access to Tank Valves
When you are diving with a back mount configuration it can be hard to reach and impossible to see your cylinder valves, making it awkward to open and close them when geared up.
Sidemount allows you to have your valves in view, making it easier and quicker to identify and isolate any issues and easily open and close valves to switch gas supplies.
Managing Your Equipment
Sidemount gives you the option to don and doff equipment in the water (subject to water conditions). This can be of tremendous aid to divers who struggle to carry single or twinsets on land. This can aid those with back issues or with disabilities who find it easier to gear up in the water.
Additionally, sidemount also allows you to unclip tanks underwater and feed them through gaps ahead of you, enabling you as a diver to squeeze through smaller spaces. This can be very useful in cave or wreck diving.
New Challenges
You might not be looking to do technical training, or squeeze through tight overhead environments so should you still think of diving sidemount? I mean after all. It is not for everyone. Well if you like to learn new skills and embrace new challenges then yes for sure.
Sidemount diving requires you to learn new skills that you don’t find in traditional back-mounted scuba diving. If you are like me and just want to learn as many skills as possible and keep yourself developing then this is definitely worth it.
New skills introduced include but are not limited to Managing more than one tank, new control of buoyancy and trim, and new equipment positions. What a challenge, which can be very rewarding.
What will Happen on the PADI Sidemount Diver Course?
Ok there is some PADI eLearning to complete as part of the knowledge development section of the PADI Sidemount Diver Course. During this and workshops with your PADI Instructor, you will learn about the theory of sidemount diving, as well as the gear configurations and equipment options that are available to you. You will also be introduced to
Benefits, and drawbacks of sidemount diving

Emergency procedures.
You will make 3 open water dives on Sidemount over 1 or 2 days as part of the course following mastering the techniques in the pool.
Once all performance requirements have been met by you with regards to elearning, and confined and open water dives you will be issued with a PADI Sidemount Diver certification, indicating that you are qualified to use sidemount gear and dive a sidemount configuration.
I am a PADI Instructor. Can I become a Sidemount Instructor?
Yes, we can include the Sidemount Instructor training courses in a package for those PADI Instructors who complete PADI Sidemount diver training with us.
Becoming an SSI Instructor through a crossover program is an exciting step in your professional diving career. At Ocean Tribe, we offer a flexible crossover schedule that can be completed in just four days. Candidates can choose to complete it over consecutive days, split it across two weekends, or even incorporate it into a full Instructor Training Course. The crossover schedule is customisable to meet the needs of each candidate.
Please note that the Instructor Evaluation (IE), which finalizes your SSI certification, is conducted separately and takes an additional one to two days depending on the number of participants.
Orientation Session
Your SSI Instructor Crossover journey begins with a short orientation session. During this time, you will receive your academic assignments and in-water presentation tasks. Instructors will explain the course expectations, set your goals, and ensure you understand the flow of the upcoming days.
The orientation is designed to be clear, efficient, and set a positive tone for the entire program. The total duration is 1.5 hours.
Day 1: Academic Foundations and Teaching Practice
The first full day of training dives straight into the academic content. You will review Academic Sessions 1 through 6, covering essential elements like the SSI teaching philosophy, standards, and systems.
In the afternoon, you move into your first teaching presentation. You will deliver an academic lesson based on the Open Water Diver course, practicing your ability to engage and educate future divers in a classroom setting.
Day one is a full training day, with a total duration of nine hours.
Day 2: Advanced Academics and Confined Water Skills
Day two builds on the academic base from the first day. You will continue the academic review, focusing on Sessions 7 to 10. These sessions deepen your understanding of SSI’s teaching methods and customer care systems.
After the academic work, you will transition into the pool or confined water environment. Here, you will deliver your first confined water teaching presentation, simulating how you would instruct Open Water Diver students during their initial skill development.
Day two is equally packed, with a total duration of nine hours.
Day 3: Rescue Skills and Emergency Training
The third day moves into more practical, real-world rescue scenarios. You will participate in a Diver Stress & Rescue workshop, refining your ability to manage emergencies in diving environments.
Following the workshop, you return to the pool for another teaching session. This time, the focus is on demonstrating and teaching emergency ascent skills, a vital competency for any Open Water Instructor.
Day three is slightly lighter, with a total duration of six hours.
Day 4: Open Water Skills and Final Evaluation
The final day of the SSI instructor crossover program shifts to the open water. You will conduct an open water teaching presentation, guiding your fellow candidates through real-world skill demonstrations.
After the practical open water work, you will complete your final written exams. These exams test your understanding of the SSI system, teaching standards, and professional responsibilities.
Finally, you will sit down for your overall performance review, receiving feedback on your strengths and the areas where you can continue to grow as an SSI Instructor.
The last day runs for a total of seven hours and brings your training portion of the crossover to a close.
Final Step: Instructor Evaluation (IE)
After successfully completing the crossover schedule, candidates must attend the Instructor Evaluation. This evaluation takes an additional one to two days and is required for final SSI Instructor certification.
