PADI Divemaster Knowledge Review Chapter 4 Questions are explained on this page to help you understand the PADI Divemaster Knowledge Review Chapter 4 Answers.
Here I will explain all the PADI Divemaster Knowledge Review Chapter 4 Answers to help you understand all Divemaster Theory in the course. Please make sure you review this later with your PADI Instructor.
Question 1: What is the main objective of managing risks?
The goal is to minimize hazards and ensure diver safety by identifying and mitigating risks proactively.
Risk management involves recognizing potential problems before they occur and taking steps to avoid them. For example, in diving, this could mean conducting thorough pre-dive briefings, checking equipment, and monitoring environmental conditions. By planning ahead, you reduce the likelihood of accidents and create a safer experience for everyone.
Question 2: Define the expectation for professional responsibility and its legal implications.
Professionals must act as a reasonable and prudent individual would under similar circumstances to protect others from harm. Negligence—failing to meet this standard—can result in lawsuits or penalties.
This principle, often called a “duty of care,” ensures that professionals are held accountable for maintaining safety. For instance, if a dive leader skips essential safety checks and an accident occurs, they could be legally responsible for damages because their behavior fell below the expected standard.
Question 3: In a legal case, how would a professional’s typical behavior affect the outcome if they made a mistake?
Correct Answer: b. Courts focus on what occurred, not on intentions.
Courts evaluate actions based on whether they met the standard of care, not the professional’s intent. Even if someone meant well but failed to follow protocols, they could still be liable. For example, intending to help but improperly handling an emergency could lead to legal consequences.
Question 4: How does neglecting personal fitness, knowledge, or safety practices impact risk?
Correct Answer: d. All of the above.
A professional’s fitness, knowledge, and adherence to safety practices directly affect not only their own safety but also the safety of others. For example, if a dive leader is physically unfit, they may be unable to assist a struggling diver effectively, putting both lives at risk.
Question 5: Can physical stress from diving lead to serious health events in predisposed individuals?
True. Diving places stress on the cardiovascular system, especially during deep or strenuous dives. For individuals with preexisting conditions, such as heart disease, this stress can trigger severe events like heart attacks or strokes. Pre-dive health screenings and awareness of personal limits are critical.
Question 6: What is the first and most effective way to reduce risks in professional activities?
Preventing incidents by following established guidelines. Prevention is the cornerstone of risk management. For example, ensuring all divers have properly functioning equipment before a dive can eliminate potential hazards. Adhering to established procedures reduces the likelihood of accidents and ensures accountability.
Question 7: Does following established safety standards reduce legal risks?
True. In-Depth Explanation: Compliance with safety standards demonstrates professionalism and reduces liability. For instance, if an accident occurs despite following all guidelines, courts are more likely to view the professional as having acted responsibly, reducing the likelihood of legal consequences.
Question 8: How should you approach local industry regulations alongside global standards?
Correct Answer: a. Follow local regulations conservatively, along with PADI standards.
Local regulations are tailored to specific conditions, such as tides, marine life, or environmental factors. Combining these with PADI standards ensures comprehensive risk management. For instance, if local regulations restrict certain dive sites due to strong currents, following these rules ensures safety.
Question 9: Is following PADI standards enough to defend your actions during an incident?
False. While PADI standards provide a foundation, situational judgment and adaptation to local conditions are equally important. For example, a dive leader might need to modify plans based on unexpected weather changes, even if global guidelines don’t specify such adjustments.
Question 10: What is the best decision when environmental conditions make diving challenging?
Correct Answer: c. Restrict the dive to shallower depths with better conditions.
Adjusting to conditions prioritizes safety. For example, if a thermocline reduces visibility at deeper depths, limiting the dive to shallower areas ensures participants remain safe and comfortable.
Question 11: How should you apply PADI standards in various situations?
Understand the intent behind standards and adapt cautiously.
PADI standards are not one-size-fits-all; they require thoughtful application and conservative judgement. For instance, if a standard recommends a specific entry technique but local conditions make it unsafe, adapting the approach while maintaining the standard’s intent (safety) is critical.
Question 12: Are PADI Member Code of Practice and the Youth Leader’s Commitment optional suggestions or mandatory?
Answer: b. They are mandatory.
PADI Member Code of Practice and Youth Leader’s Commitment set the baseline for professional behavior and must be adhered to. You will find an in-depth explanation in the PADI Instructor Manual.
Question 13: The main role of Paperwork for PADI courses and programs is to inform them of potential risks in scuba diving.
True. Documentation ensures participants understand risks, agree to them, and verify their fitness for scuba diving.
Well-maintained documentation, such as liability waivers and PADI medical forms, protects both participants and professionals. It ensures everyone is informed and provides evidence that proper protocols were followed.
Question 14: What steps should be taken if a participant indicates a health concern on a PADI medical form?
Correct Answer: a. Require physician approval.
Medical concerns must be evaluated by a physician to avoid risks. For example, a participant with a history of asthma needs a doctor’s clearance to ensure they can scuba dive.
Important: Never make medical decisions as a PADI Divemaster. You should always advice them to seek medical advice from a licensed Physician if they have a health concern.
Question 15: What is the likely effect of offering opinions based on experience and not actually being present during an accident?
Correct Answer: b. Could confuse the situation due to lack of observed facts.
Opinions not based on direct observation can mislead investigations. For example, speculating that a diver panicked without evidence might distract from identifying the actual cause.
If you’re getting ready to travel to Thailand, you’re likely doing a lot of research right now! You’re probably excited, maybe a little nervous, and ready to start your travels! As with any trip abroad, it is a wise idea to plan ahead to ensure safe and successful international travel. One of the best ways to ensure a memorable and enjoyable trip to Thailand or another Asian country is to purchase travel insurance for yourself. Buying traveling insurance can help provide you with assistance in case of a medical emergency or unexpected travel delay.
If you’re traveling to Thailand in particular, it is critical to note that the Thai government legally requires all foreign visitors to carry travel insurance, or they will be denied entry to the county. In addition, the Thai embassy also requires that visitors also possess the following documents for their entry to the country:
Passport
Visa (if required)
Flight Itinerary
Hotel booking confirmation
Vaccination record (if vaccinated)
COVID-19 test result (if unvaccinated)
Ensuring you have all proper documentation (including travel insurance) helps ensure smooth and safe travel internationally, allowing you to kick back and enjoy your trip!
Ten Reasons to Get Travel Insurance for Thailand
Besides just being legally required to, what are some of the other top reasons to buy travel insurance for Thailand? Getting travel insurance is one of the smartest ways to protect yourself while traveling internationally. Here are ten practical reasons to get travel insurance before your next trip abroad!
1. Protecting Against Surprise Medical Expenses
Help protect yourself from unexpected medical costs if you become ill or injured while abroad. Travel insurance can help cover things like:
Emergency medical care (like ambulance rides)
Car accidents
Injuries such as falls
ER trips
Routine check-ups
Other non-urgent care
Hospitalizations
Having a medical emergency or illness abroad can be devastating (financially and otherwise) if you don’t have the proper insurance coverage or planning in place. Travel insurance helps prevent these situations before they ever happen and assists in managing them when they do.
2. Emergency Evacuation Options
Requiring emergency evacuation while traveling internationally can be a very complicated situation logistically, on top of everything else that you’re going through. Not only does travel insurance cover your emergency evacuation, but it can also cover things like:
A medical aide to travel with you
A friend or family member’s travel costs
Emergency transportation
Repatriation (return) of remains
3. Coverage for Missing or Stolen Possessions
Not only is losing possessions abroad annoying, but it can also be very expensive financially, as well as extremely inconvenient during your trip. Travel insurance policies can provide coverage for lost or stolen luggage and personal items, so your trip doesn’t have to end or be ruined due to an unfortunate mishap.
4. Reimbursement for Cancellations and Changes
Ensure that you are reimbursed for any prepaid, non-refundable travel expenses in case of trip cancellation due to illness or injury. Many travel insurance policies offer coverage for additional accommodations or flight rescheduling, should you end up needing it.Some common reasons for trip delays, cancellations, or interruptions often include:
Bad weather
Airline strikes
Staff shortages
COVID-19-related travel restrictions
Political unrest
Nature disasters
Travel can be unpredictable at times, but having a travel insurance policy that provides reimbursement in case of rescheduling or cancellations can help you avoid these bumps in the road while planning your next international trip.
6. Having a No-Questions Cancellation Option
Many travel insurance policies allow you to cancel for any reason—no questions asked. Whether you’ve had something important come up that just can’t be rescheduled or you’re dealing with a family emergency, you can have peace of mind knowing you’re protected, should you have to cancel or reschedule your trip. It’s a great policy option to have in today’s unpredictable world as you embark on your next journey.
7. Legal Assistance and Protection
Travel insurance provides financial assistance in case of legal problems arising from an accident while traveling abroad (like negligence or car rental accidents). Having this kind of coverage is an excellent way to protect yourself abroad if you find yourself in any sort of legal trouble. Remember, it’s always better to have this coverage and not end up needing it, than to find yourself lacking and in a sticky situation!
8. Access to 24/7 Customer Support
Let’s face it, traveling abroad can be exciting and fun, but it can inevitably come with its stressful and challenging moments too, even for the experienced traveler. Luckily, with travel insurance, you can enjoy 24/7 customer service support with access to multilingual staff. They’re trained in assisting and supporting travelers just like you and can help with any issues that may arise while traveling abroad (such as lost passports).
9. Protection from Currency Fluctuations
Help protect yourself against financial losses with travel insurance. Policies can factor in and shield your finances from currency fluctuations in the destination country’s currency (if applicable). Inflation and political unrest can affect currency fast, so it’s smart to protect yourself well in advance of traveling.
10. Security and Peace of Mind
Travel insurance provides peace of mind and a feeling of security while traveling abroad. Relax and enjoy your trip, knowing that you have taken all necessary precautions to ensure a safe and memorable trip abroad!
Traveling Safely in Thailand and Asian Countries
Travel insurance protects you while you are traveling. It covers a variety of situations and emergencies, including:
Medical expenses
Medical evacuations
Lost or stolen luggage
Cancellations
Legal situations
Moments where you need help or guidance traveling
Currency fluctuations
Choosing Travel Insurance
When selecting your unique travel insurance policy, there are several other factors to consider. Here are three elements to consider when choosing a travel insurance policy!
Your Unique Coverage Needs
When selecting travel insurance, it is important to determine what type of policy best suits your needs. If you are traveling for business purposes, your needs may be different than someone vacationing who may be doing risky activities such as hiking or scuba diving. In addition, if you plan to visit multiple countries during your trip, you need to make sure that your policy covers all of them.
Any Pre-Existing Conditions You May Have
It’s critical to ensure that the policy covers any pre-existing medical conditions you may have. Many policies will not cover medical expenses related to pre-existing conditions unless they are specifically listed in the policy. It is also important to check what kind of medical care is covered by the policy and whether there are any limits on how much can be claimed for a particular incident or illness.
The Fine Print of Your Policy
Be sure to read through the fine print of the policy carefully before signing up for it. Before signing, you must understand all of the terms and conditions. This ensures that there are no surprises later on if something unexpected happens while you’re away from home.Check what kind of emergency assistance services are included with your travel insurance plan and whether they offer 24/7 customer support in case something goes wrong while abroad.
Preserve All Policy-Related Documents
Make sure that you keep all relevant documents related to your travel insurance plan safe and accessible in case anything happens while traveling abroad. This includes copies of receipts for any purchases made with your credit card as well as proof of payment for your travel insurance plan itself so that any claims can be processed quickly and efficiently if necessary.

The Fin Pivot is one of the oldest techniques that you can use to practice controlling your buoyancy with your lungs. It is very important to have great buoyancy while scuba diving and try to use our lungs as the main part to control that buoyancy. The Fin Pivot is perfect to learn to use your lungs the right way in the beginning or your scuba diving lessons.
The Fin Pivot used to be a performance requirement in the PADI Open Water Diver Course. Some years ago PADI updated standards and made it a flexible technique to choose when practicing buoyancy with your students.
The reason for this was because many people had what we call floaty ankles. This made it very hard on them to perform this scuba diving skill. So now it is optional to teach the Fin Pivot in the Open Water course. If you choose not to teach the Fin Pivot, then you need to replace it by another buoyancy technique like for example hovering.
Steps for the PADI Fin Pivot Skill
1. Make sure you are fully deflated
2. Lay flat on your belly
3. Spread your legs and try to stretch them
4. Inhale and see if you start to rise
5. If not than add a little bit of air into your BCD by using the inflator button of your LPI
6. Take another deep breath (if you still don’t rise, then repeat the steps before)
7. When you inhale you should start to rise
8. When you start rising start exhaling as there is a delay in buoyancy and the size of your lungs
9. try not to kick, scull and do “push-ups” with your hands
10. Be streamlined and only rise and fall using your lungs
Important: Make sure the when you perform the Fin Pivot that your fins are not touching any aqua life.
Have a look at this video we made for the Fin Pivot skill:
Floaty ankles can be an annoyance while scuba diving. Especially if you try to perform the PADI Fin Pivot Skill. To solve floaty ankles we recommend you to purchase heavy fins and/or ankle weights. Have a look at these two items:
Frequently Asked Questions About the Fin Pivot in Scuba Diving
What is the Fin Pivot in scuba diving?
The Fin Pivot is a foundational technique used in scuba diving to practice and understand buoyancy control. By lying prone on the bottom and using controlled breathing, divers learn to rise and fall gently, achieving neutral buoyancy. This exercise emphasizes the role of lung volume in buoyancy adjustments.
Why is mastering the Fin Pivot important for divers?
Mastering the Fin Pivot helps divers develop precise buoyancy control, leading to:
Reduced air consumption.
Minimized contact with the aquatic environment, preserving marine life.
Enhanced comfort and control underwater.
It lays the groundwork for more advanced skills like hovering.
Is the Fin Pivot still a required skill in PADI courses?
While the Fin Pivot was once a mandatory skill in the PADI Open Water Diver course, it has become optional in recent years. Instructors may choose to teach it or substitute it with other buoyancy exercises like hovering, depending on student needs and course structure.
What are the steps to perform the Fin Pivot correctly?
Fully deflate your BCD.
Lie flat on your stomach on the bottom.
Extend your legs with fins touching the ground.
Inhale deeply; your upper body should rise.
Exhale slowly; your body should lower back down.
Avoid using hands or kicking; rely solely on breath control for movement.
How does the Fin Pivot differ from hovering?
The Fin Pivot involves maintaining contact with the bottom, using fins as a pivot point, and focusing on vertical movement through breathing. Hovering requires maintaining a stationary position mid-water without any contact, demanding more advanced buoyancy and trim control.
What equipment can assist with performing the Fin Pivot?
Divers experiencing “floaty ankles” can benefit from:
Heavy fins: Such as ScubaPro Jet Fins, which help anchor the legs.
Ankle weights: Like Trident Ankle Weights, to counteract buoyant tendencies in the lower body. scubadivingtips.net
Can the Fin Pivot be practiced in all diving environments?
The Fin Pivot is best practiced in controlled environments like pools or sandy bottoms where contact won’t harm marine life. In sensitive ecosystems, divers should avoid bottom contact and focus on mid-water buoyancy exercises to prevent environmental damage.
How does mastering the Fin Pivot benefit overall diving skills?
Proficiency in the Fin Pivot enhances a diver’s ability to control buoyancy using breath, leading to improved air efficiency, better positioning in the water column, and a foundation for advanced techniques like hovering and precise maneuvering.
Are there visual resources to learn the Fin Pivot?
Yes, visual demonstrations can be highly beneficial. For instance, the “Fin Pivot – PADI Open Water Diver Course” video provides a clear demonstration of the technique seen above shows this or watch the full PADI Open Water Skills video:
The Giant Stride entry is one of the safest and most comfortable entries when you are scuba diving from a bigger boat. It depends on the size and hight of a boat what entry you choose. The Giant Stride entry is one of the best options especially if you are nervous to enter the water for the first time.
Giant Stride Entry
Usually when you scuba dive from the beach we just walk into the water using the sloping bottom contour. When we dive from a small boat we roll backwards into the water or put the dive equipment on in the water. When we are on a larger boat the some people prefer to enter backwards, however we found out that in most cases the Giant Stride Entry is much better.
In this video we used the Scuba Pro Jet Sport Fins. These fins are a personal favourite of mine. They are very light for traveling, very easy to put on and most important they are extremely comfortable to move around with underwater. Check them them out on Amazon below:
Frequently Asked Questions About the Giant Stride Entry
What is the Giant Stride entry in scuba diving?
The Giant Stride is a common water entry technique used in scuba diving, especially from stable platforms like boats or docks. It involves taking a large step forward into the water while wearing full scuba gear, ensuring a controlled and safe entry.
How do I perform a Giant Stride entry correctly?
To execute a Giant Stride entry:
Inflate your BCD to about 70% to ensure buoyancy upon entry.
Stand at the edge of the platform with your toes overhanging and fins extending beyond the edge.
Place your right hand over your regulator and mask to keep them in place.
Use your left hand to secure your weight belt buckle or the back of your head to hold the mask strap.
Look straight ahead to maintain balance and orientation.
Take a large step forward, ensuring your legs are in a scissor position during the descent.
Upon surfacing, fully inflate your BCD, switch to your snorkel if desired, and signal to the boat crew that you’re okay.
Why is the Giant Stride entry preferred in certain situations?
The Giant Stride is favored when entering deep water from stable platforms because it allows divers to enter the water smoothly and maintain control. It’s especially useful when the entry point is elevated, as it helps prevent contact with the platform or boat.
Are there common mistakes to avoid during a Giant Stride entry?
Yes, common mistakes include:
Failing to check the entry area for obstacles or other divers.
Not securing the mask and regulator, leading to potential dislodging upon impact.
Insufficient BCD inflation, which can result in sinking below the surface.
Looking down during the step, which can affect balance and orientation.
Not stepping out far enough, risking contact with the platform or boat.
Can the Giant Stride entry be used in all diving environments?
No, the Giant Stride is best suited for entries from stable, elevated platforms into deep water. In environments with unstable platforms, shallow water, or when diving from small boats, alternative entry methods like the back roll or seated entry may be more appropriate.
Is the Giant Stride entry taught in scuba certification courses?
Yes, the Giant Stride is commonly taught during scuba certification courses, such as the PADI Open Water Diver course. It helps students learn proper entry techniques and build confidence in entering the water with full gear.
What equipment considerations are there for the Giant Stride entry?
When performing a Giant Stride, ensure:
Fins are properly secured to prevent loss upon entry.
All gear is streamlined to minimize drag and potential entanglement.
Loose accessories are stowed or secured to prevent them from catching on the platform or boat.
Are there visual resources to learn the Giant Stride entry?
Yes, visual demonstrations can be highly beneficial. For instance, the “How To | Giant Stride” video seen above provides a clear demonstration of the technique.
PADI Divemaster Knowledge Review Chapter 3 Questions are explained on this page to help you understand the PADI Divemaster Knowledge Review Chapter 3 Answers.
Here I will explain all the PADI Divemaster Knowledge Review Chapter 3 Answers to help you understand all Divemaster Theory in the course. Please make sure you review this later with your PADI Instructor.
Question 1: What is your primary role as a professional assistant during training?
Your primary role includes managing logistics (e.g., organizing equipment, ensuring smooth transitions between activities) and supervision (e.g., keeping an eye on student divers who aren’t under direct instructor observation). This ensures that the instructor can focus on teaching and evaluating skills while maintaining a safe and efficient learning environment.
Question 2: Identify your possible functions during training (choose all that apply):
Supervising equipment distribution and collection: Ensures all divers have the right gear and that it is stored properly post-dive.
Supervising divers not being directly observed by the instructor: Adds an extra layer of safety for students in different areas of the dive site.
Handling logistics: Keeps training flowing smoothly by coordinating diver flow and session timing.
Conducting experience dives: Guides divers during the “tour” portion, allowing them to practice skills in a controlled yet realistic setting.
Providing feedback to the instructor: Helps identify individual student needs and performance issues for better instructional focus.
Checking divers in and out of the water: Tracks who is in the water, ensuring no one is left behind.
Assisting students with learning challenges: Offers one-on-one support for students struggling with skills, boosting their confidence and understanding.
Question 3: Why might students feel more comfortable sharing concerns with you rather than the instructor?
Students may perceive you as being closer to their level, making it easier to approach you with concerns. While instructors are seen as authority figures, you act as a bridge between the instructor and students, helping to address issues that students might hesitate to bring up directly with the instructor.
Question 4: If the dive bottom is silty during training, which arrangement is best for minimizing disturbances?
Arranging students in a line with the instructor in the center and you positioned above and behind minimizes the risk of stirring up silt. This configuration allows for efficient skill rotation while keeping the dive area undisturbed, ensuring visibility for both the instructor and the students.
Question 5: Is holding the BCD at the shoulder or low on the outside a good method for making direct contact with a student?
True. This method ensures you maintain control over the diver’s movements without compromising their comfort or safety. Holding the BCD at the shoulder or lower side allows for a secure grip while avoiding invasive or restrictive contact.
Question 7: Why might you demonstrate a skill? (Choose all that apply):
When the skill requires two people: For example, buddy-assisted skills like alternate air source sharing require both the instructor and an assistant.
To redemonstrate for a student with difficulties: Seeing the skill demonstrated again can help a struggling student understand proper techniques and improve.
Question 8: What is the most important factor in developing demonstration-quality skills?
Practice. Watching demonstrations and videos is helpful, but consistent hands-on practice builds muscle memory, confidence, and the ability to perform skills flawlessly under pressure.
Question 9: Do you only need the 20 basic skills from entry-level training and 4 skills from skin diving training at demonstration quality?
False. While these skills form the foundation, you may need demonstration-quality proficiency in other skills depending on the program or situation. Expanding your skillset ensures you can support advanced or specialty training effectively.
Redemonstrating the skill is often the best first step. By showing the correct technique, you provide a visual example for the student to follow. This approach is less intimidating than pointing out errors or having the student attempt the skill without understanding what they’re doing wrong.
Question 11: Where can you find specific requirements for working with children?
Both the Professional Membership Guide and Child Protection Guidelines outline requirements for working with children. These resources cover safety protocols, legal considerations, and best practices for interacting with minors in diving programs, ensuring compliance and safeguarding the well-being of young participants.
Question 12: Should you allow a student to handle a problem themselves unless safety or logistics require intervention?
True. Allowing students to work through problems fosters independence and critical thinking. However, you should step in immediately if safety is compromised or if the problem hinders the flow of the session.
Question 13: When assisting a student with physical challenges, where should your focus be?
Focus on what the student can do. Emphasizing their abilities rather than limitations builds confidence and encourages them to approach skills with a positive mindset. Adapt techniques to their strengths to ensure success without drawing unnecessary attention to their challenges.
Scuba Refresher Course is one of the best ways to get back to scuba diving comfortably. After some time of no scuba diving, you might feel a bit rusty and you would love to refresh yourself. The Scuba Refresher Course covers all the important scuba diving skills before your next scuba dive.
The Scuba Refresher Course is fantastic as it covers all the scuba diving training you had before. In this Scuba Refresher Course, you will review your scuba skills, scuba theory knowledge, and other scuba review topics to make sure you can comfortably and more importantly safely continuing diving.
Just remember that all this information is here to help you prepare. You should always take a scuba refresher with a certified Divemaster, Instructor and Dive Shop.
How often to do a scuba refresher?
When should I get my scuba diving certification refreshed or how often to do a scuba refresher are common questions asked. It depends on your scuba diving training organization what their standards are on how often you should do a scuba diving refresher course. This can be 6 months, 12 months, or even longer after your last scuba dive. It also depends on your experience level.
It also depends on your Dive shop’s own rules. Some dive shops are stricter than others. To be honest, I think you should always follow your dive training organization standards on how often you should do a scuba refresher course, but if they are not available then I recommend every 6 months with no scuba diving activity. In the end, it is about your safety, so why not be safe and do a scuba diving refresher course often.
How much does a scuba diving refresher course cost?
This depends on the location and the Dive shop, but in general, it is between 20 to 100 USD around the world. We have heard people complaining about the scuba diving refresher course cost as they just want to fun dive. However, a scuba refresher course can not only save your life, but it will make your scuba fun dive so much more enjoyable. There is no price tag to put on that. For only 20 to 100 USD you can feel safe, comfortable, and enjoy your dives after a period of no diving with an easy and fun scuba diving refresher course. That should be a no-brainer. The scuba diving refresher course is really valuable.
This also depends on your scuba training organization. Some organizations want you to repeat a strict amount of scuba skills during your refresher course while others are less strict and let you choose what scuba skills you would like to practice/repeat during your scuba diving refresher course. In our youtube video we cover most scuba skills that you might encounter in your scuba diving refresher course. Possible Scuba Diving Refresher Course Skills:
Should I refresh myself in confined water (swimming pool) or open water?
I recommend refreshing yourself first in confined water and if needed ask a Divemaster or Diving Instructor to refresh your scuba skills also in the open water. When you feel comfortable enough you can sign up for a fun dive again or continue your scuba diving education by joining the next course. For example, a lot of people only do the first open water diver course and then might need a scuba diving refresher course before they join the second advanced open water diver course.
If you are interested in doing a scuba diving refresher course with us then you can find more information here.
