Oceans 5 Gili Air offers more than dive trips and beginner courses. Our work now includes Divemaster internships, instructor training, technical diving and marine conservation. We have developed dedicated websites for these areas so you can find detailed information about the program that interests you. …
How Far Can Scuba Diving Take You? For many people, scuba diving begins with one simple idea: I want to see what is underwater. Maybe it starts with an introduction dive while travelling through Indonesia. Maybe it is an Open Water Diver course on Gili Air. …
The Gili Islands are famous for scuba diving.
Every year, divers travel to Gili Air, Gili Meno and Gili Trawangan to explore warm tropical waters, coral reefs, walls, wrecks and dive sites where encounters with sea turtles are part of everyday diving.
But there is another side to diving around the Gili Islands that deserves just as much attention.
Marine conservation.
The underwater environment that attracts divers from around the world cannot simply be taken for granted. Coral reefs face pressure from climate change, coastal development, pollution, marine debris, irresponsible tourism and the cumulative impact of thousands of people using a relatively small marine environment.
At Oceans 5 Gili Air, we believe divers can be part of the solution.
Marine conservation doesn’t necessarily begin with a major scientific project. It can start with something as simple as controlling your buoyancy, keeping your fins away from coral, refusing to touch marine animals and understanding the protected area in which you are diving.
For divers visiting the Gili Islands, responsible diving should simply be part of good diving.
Gili Air, Gili Meno and Gili Trawangan are surrounded by the Gili Matra marine conservation area.
This means that when we go diving around the three islands, we aren’t simply visiting recreational dive sites. We are entering a marine environment that has been designated for conservation and managed through regulations and zoning.
For a deeper introduction to the area, read our guide to the Gili Matra Marine Park.
Understanding this is important.
Marine protected areas don’t protect themselves.
A line on a government map cannot stop somebody standing on coral. A regulation cannot physically prevent a diver from chasing a turtle. A protected status cannot remove plastic from a beach or automatically prevent pollution from reaching the ocean.
Protection depends on people.
That includes government authorities, local communities, businesses, dive centres, scientists, conservation organisations and visitors.
It also includes you as a diver.
For more information about conservation, regulations and environmental issues affecting the three islands, visit Gili Conservation Dive.
Sometimes we make conservation sound complicated.
It can involve scientific surveys, water-quality analysis, coral monitoring, species identification and long-term datasets.
Those things are important.
But there is another form of conservation happening every day on the reefs around the Gili Islands:
responsible diving.
Imagine hundreds of divers visiting the same reef every week.
One diver accidentally touching coral may seem insignificant. One pair of fins kicking the reef might appear to cause little damage. One person holding onto coral for a photograph may not look like a major environmental problem.
Multiply those actions by thousands of dives.
Suddenly, diver behaviour matters enormously.
That is why Oceans 5 places so much emphasis on neutral buoyancy.
Our students are taught skills while neutrally buoyant rather than routinely kneeling on the bottom. Certified divers are expected to maintain good buoyancy and avoid contact with the reef.
The philosophy is simple:
Look, enjoy and photograph — but don’t touch.
Divers who want to understand this approach in greater detail can read the guide to responsible diving in the Gili Islands.
One of the most valuable conservation skills a diver can develop is excellent buoyancy.
A diver who has good control can hover comfortably above the reef without using the bottom for stability.
This protects coral, but it also makes you a better diver.
You use less energy.
Your breathing becomes more relaxed.
Your air consumption can improve.
Your photographs become easier to take.
And you are much less likely to accidentally damage the environment.
This is one reason Oceans 5 doesn’t see buoyancy as something students should learn after becoming certified.
It should be part of learning to dive from the beginning.
Marine conservation and good diver training are directly connected.
The Gili Islands are particularly well known for sea turtles.
For many visitors, seeing a green or hawksbill turtle underwater becomes one of the highlights of their holiday.
But seeing an animal doesn’t give us the right to interfere with it.
Divers should never chase, touch, grab, feed or block marine animals for photographs.
The same applies to sharks, rays, octopuses, moray eels, nudibranchs and every other animal we encounter.
A good wildlife encounter is one where the animal can continue behaving naturally.
Instead of asking:
How close can I get?
Try asking:
How can I observe this animal without changing its behaviour?
That small change in attitude makes a considerable difference.
Responsible divers should also understand that marine conservation isn’t based solely on voluntary behaviour.
Protected marine areas have rules.
These can relate to zoning, fishing, anchoring, tourism activities, environmental protection and the ways different parts of the marine area can be used.
Visitors don’t need to become experts in Indonesian environmental law before going diving.
But understanding the basic principles of the protected area you’re visiting is part of responsible tourism.
You can learn more through the Gili Matra Marine Park rules and conservation information.
The important point is that marine park rules exist for a reason.
The Gili Islands are simultaneously a home, tourism destination, business environment and protected marine ecosystem.
Finding the balance between those different uses is essential for their future.
It is easy for divers to think of marine conservation as something that happens underwater.
Unfortunately, the ocean doesn’t work that way.
What happens on land can eventually affect the sea.
Waste management, wastewater, coastal construction, groundwater, rubbish and development can all potentially influence the surrounding marine environment.
That is why Oceans 5 believes marine conservation should include prevention, not simply repairing environmental damage afterwards.
We explored this subject in detail in From Reaction to Prevention: Why Marine Conservation Must Start Before a Reef Collapses.
Coral restoration can be valuable.
Beach clean-ups can be valuable.
Reef restoration can be valuable.
But we should also be asking:
Why was the ecosystem damaged in the first place?
If we can identify and reduce environmental pressures before major damage occurs, that can be far more effective than trying to repair an ecosystem afterwards.
People who have been diving around the Gili Islands for many years have seen changes underwater.
Some are natural.
Others may be connected with global or local environmental pressures.
Climate change, increasing sea temperatures, coastal development, tourism pressure, pollution and extreme weather can all influence coral reef ecosystems.
Oceans 5 has been operating on Gili Air since 2010, which means our team has had the opportunity to observe the reefs over many years.
We discussed some of those observations in Why Coral Reefs Around the Gili Islands Are Changing.
Observation isn’t the same as scientific proof.
That distinction matters.
Seeing algae somewhere doesn’t automatically tell us why it appeared. Seeing coral decline doesn’t immediately identify the cause.
But observations can create questions.
And questions can lead to research.
Marine conservation needs evidence.
Without data, it becomes very easy for discussions about environmental problems to become based on assumptions, anecdotes or personal interests.
That is why Oceans 5 supports marine research around the Gili Islands.
Our cooperation with the University of Mataram gives Indonesian university students opportunities to gain practical experience collecting marine data around Gili Air, Gili Meno and Gili Trawangan.
Oceans 5 can provide resources that would otherwise be expensive for students and researchers to access: boats, scuba equipment, tanks, compressors, facilities and experienced dive professionals.
You can read more about the development of this cooperation in Oceans 5’s partnership with the University of Mataram.
Supporting research doesn’t mean deciding what the research should conclude.
Quite the opposite.
Good conservation requires independent data.
Indonesia contains some of the world’s most extraordinary marine ecosystems.
Their long-term future should involve Indonesian scientists, students, conservationists and dive professionals.
This is one reason education has become such an important part of Oceans 5’s conservation philosophy.
Indonesian university students participating in conservation programs at Oceans 5 receive opportunities to improve their diving abilities and marine-species knowledge while developing practical experience in the field.
Oceans 5 has supported students with SSI Ecology training covering subjects such as coral identification, shark ecology and sea turtle ecology.
You can read more about how Oceans 5 is supporting future Indonesian marine scientists.
For more information about the broader education and community programs connected with conservation around Gili Air, visit Community & Education at Gili Conservation Dive.
Conservation isn’t only about coral.
Long-term conservation works best when local communities are involved and benefit from protecting their environment.
Education, professional dive training and access to employment can therefore be part of a broader conservation strategy.
Oceans 5 provides a Divemaster internship opportunity for Indonesian citizens, helping Indonesians develop professional-level diving experience and potentially build careers within Indonesia’s diving industry.
More information about this initiative can be found through Gili Conservation Dive’s Indonesian Divemaster Internship information.
Developing local dive professionals matters.
People who live and work around Indonesia’s marine environments can become some of their strongest long-term advocates.
Not every conservation action requires a university, laboratory or research vessel.
Sometimes you simply need a pair of gloves and a rubbish bag.
Oceans 5 has been organising beach clean-ups on Gili Air since 2010.
Every Friday at 17:00, our team, Divemaster candidates, visitors and volunteers meet at Oceans 5 and clean sections of the beach and surrounding areas.
Sometimes we collect relatively small amounts.
Sometimes we collect tens of kilograms.
The next week, we do it again.
And again.
And again.
That consistency matters.
A single beach clean-up makes a beach cleaner for a day.
A conservation culture can change people’s behaviour for much longer.
If you’re on Gili Air on a Friday, you’re welcome to join us.
There is another issue that the diving industry shouldn’t avoid.
Dive centres make money because people want to experience the ocean.
We sell scuba courses.
We organise fun dives.
We train Divemasters.
We train SSI instructors.
We take people to coral reefs.
Healthy marine ecosystems are therefore economically valuable to our industry.
At Oceans 5, we believe that creates responsibility.
This is why we invest our own resources into conservation activities rather than making every project dependent on outside donations or grants.
We explain that philosophy further in Why Oceans 5 Invests Its Own Money in Marine Conservation.
Our boats, tanks, compressors, swimming pools, classrooms, equipment and staff exist primarily because we’re a dive centre.
But those same resources can also support students, scientists and conservation activities.
For us, the two shouldn’t be separated.
You don’t need to become a marine biologist to make a difference.
Start with your own diving.
Develop excellent buoyancy.
Keep your fins away from coral.
Don’t kneel on the reef.
Don’t touch marine animals.
Don’t chase turtles or sharks for photographs.
Don’t take anything from the ocean.
Reduce unnecessary plastic.
Listen carefully to environmental information in your dive briefing.
Respect marine park regulations.
Choose dive operators that take environmental responsibility seriously.
Participate in a beach clean-up.
And perhaps most importantly:
Stay curious.
Ask questions about the environment you’re diving in.
Learn what you’re looking at.
Understand why the marine area is protected.
The more divers understand the underwater world, the stronger the connection becomes between enjoying it and protecting it.
Oceans 5 opened on Gili Air in 2010.
Since then, conservation has increasingly become integrated into how we operate, teach and think about diving.
We don’t believe one beach clean-up will save the ocean.
We don’t believe one research project will answer every question.
And we don’t believe putting the word “eco” or “conservation” on a website automatically makes an organisation sustainable.
Marine conservation requires consistency.
It requires education.
It requires research.
It requires responsible tourism.
It requires government.
It requires local communities.
And it requires businesses to accept responsibility for the environments from which they benefit.
Most of all, it requires time.
We have created Gili Conservation Dive as a dedicated resource for people who want to learn more about marine conservation around Gili Air, Gili Meno and Gili Trawangan.
The website brings together information about the Gili Matra Marine Park, responsible diving, conservation rules, marine ecosystems, environmental issues, education, research and community initiatives.
Visit Gili Conservation Dive – Marine Conservation in the Gili Islands to explore the project.
Because protecting the Gili Islands shouldn’t only matter while we’re underwater.
It should matter long after the dive is over.
Marine conservation around the Gili Islands involves protecting coral reefs, marine animals and the wider coastal ecosystem surrounding Gili Air, Gili Meno and Gili Trawangan. It includes marine protected-area management, responsible diving, research, education, pollution prevention, waste reduction and community participation.
Yes. Gili Air, Gili Meno and Gili Trawangan form part of the Gili Matra marine conservation area. Divers and visitors should respect the applicable zoning, regulations and environmental protections.
Divers can maintain good buoyancy, avoid touching coral and marine life, never chase animals for photographs, reduce waste, follow marine park rules and choose environmentally responsible dive operators.
Yes. Oceans 5 organises a beach clean-up every Friday at 17:00, and visitors are welcome to participate.

The protection, management and responsible use of Gili Matra are supported by several layers of Indonesian law. Together, these regulations govern conservation zoning, coastal development, environmental protection, wastewater and pollution, business activities, public access and the use of small islands.
Among its key provisions:
National legislation does not operate by itself. Provincial, regency and village regulations may impose additional or more detailed requirements concerning:
A land certificate, business licence or village approval does not automatically override environmental, spatial-planning, coastal-setback or conservation requirements. A project may need to comply with several different approvals at the same time.
Gili Matra does not suffer from a lack of laws. The greater challenge is consistent implementation, monitoring and enforcement.
A conservation-area designation has little practical value if zoning rules are ignored, buildings extend into protected coastal setbacks, untreated wastewater enters the environment, beaches become privately obstructed or developments exceed the islands’ freshwater and waste-management capacity.
Effective protection requires cooperation between the Ministry of Marine Affairs and Fisheries, the conservation-area management authority, environmental authorities, the West Nusa Tenggara Provincial Government, the North Lombok Regency Government, village governments, local communities and businesses.
It also requires transparent spatial plans, clearly marked conservation zones and coastal boundaries, routine environmental monitoring, investigation of reported violations and meaningful sanctions when regulations are breached.
This overview is intended as public information and not as formal legal advice. The official Indonesian text of each regulation and the latest provincial and regional spatial plans should be consulted when assessing a particular activity or development.
What Are You Actually Paying For? When comparing scuba-diving prices, it is tempting to choose the lowest number. A fun dive is a fun dive, right? You receive a tank, join a boat, go underwater and return to shore. Why pay more when another dive …
Cannot Control Their Buoyancy A scuba certification gives someone permission to dive within the limits of their training. But does a certification card automatically prove that the diver is currently capable of diving safely? The honest answer is no. Some certified divers return to the …
You finish a beautiful dive around the Gili Islands and look at your pressure gauge.
You have 50 bar remaining. Your buddy still has 90 bar, and the Divemaster appears to have barely used any air.
Does that mean you are a bad diver?
No.
Air consumption varies considerably between divers. Body size, depth, experience, physical effort, current, equipment, buoyancy, stress and even how interested you are in what you see can all influence how much gas you use.
It is natural to want to improve, but air consumption should never become a competition.
The objective is not to return to the boat with more air than everyone else. The objective is to breathe normally, monitor your pressure, communicate honestly and complete the dive with a safe reserve.
Your pressure gauge provides safety information. It is not a scorecard.
Every diver is different.
A larger person will generally need more breathing gas than a smaller person because they have a larger lung volume and their body requires more oxygen. This does not automatically mean that the larger diver is less efficient or less experienced.
Air consumption can also be influenced by:
DAN notes that recreational divers’ breathing rates can vary widely depending on body size, stress and workload.[1] Comparing your remaining pressure directly with another diver therefore tells you very little unless you used identical cylinders and followed the same depth profile under similar conditions.
Even then, you are still comparing two different bodies.
Divers often assume that they used more air because they were nervous or inefficient. Sometimes the main explanation is simply depth.
The deeper you dive, the greater the surrounding pressure. Your regulator must provide breathing gas at the pressure of the surrounding water. This means every breath taken at depth uses more gas from your cylinder than the same-sized breath at the surface.
At approximately 10 metres, the surrounding pressure is about twice the pressure at the surface. At 20 metres, it is about three times the surface pressure. At 30 metres, it is approximately four times greater.
A diver breathing 15 litres per minute at the surface would use the equivalent of approximately:
SSI explains that gas consumption increases with depth and that physical effort raises a diver’s breathing rate.[2] DAN uses the same relationship when teaching divers how to calculate their Surface Air Consumption rate and estimate the gas required for a dive.[3]
This is why a deep dive normally uses more air than a relaxed shallow dive, even when the diver’s breathing pattern feels exactly the same.
It is also why moving a little shallower can sometimes extend a dive without requiring the diver to do anything unnatural with their breathing.
Swimming against a current requires more effort. More effort means the body needs more oxygen and produces more carbon dioxide. The diver must breathe more to meet this demand and remove the additional carbon dioxide.
The same can happen when a diver:
DAN explains that greater exercise and greater depth both increase breathing-gas requirements.[4]
If you are swimming hard at 25 metres while your buddy is relaxed at 18 metres, comparing the two pressure gauges is meaningless. You have not completed the same dive physiologically, even if you entered the water together.
Breathing often becomes faster when a diver feels nervous.
This is common among:
The last example can create a frustrating cycle.
The diver notices that their pressure is dropping, becomes concerned, starts thinking constantly about breathing and becomes less relaxed. Their breathing rate then increases further.
Trying too hard to save air can have the opposite effect.
The best response is usually not to force your breathing. Slow down, establish neutral buoyancy, move a little shallower if appropriate, stay close to your buddy and guide, and allow your breathing to settle naturally.
Some divers try to make their air last longer by pausing for an unnaturally long time between breaths. Others begin skip-breathing: inhaling, holding the breath and then exhaling.
This is not a safe or effective solution.
Holding your breath can allow carbon dioxide to accumulate. An increased carbon-dioxide level can contribute to headache, breathlessness, anxiety and a feeling that you cannot get enough air. It may also create an even stronger urge to breathe.
Most importantly, scuba divers must never hold their breath while ascending. As the surrounding pressure decreases, gas inside the lungs expands. If it cannot escape, the expanding gas can damage lung tissue and potentially cause an arterial gas embolism.[5]
The safer approach is to maintain continuous, relaxed breathing.
SSI recommends a deep, balanced and rhythmic breathing pattern while diving.[2] Do not try to take the smallest breaths possible. Breathe normally and comfortably.
Efficient breathing is relaxed breathing—not restricted breathing.
Air consumption often improves as divers gain experience.
This does not happen because experienced divers develop smaller lungs or need less oxygen. It happens because many unnecessary movements, worries and corrections gradually disappear.
With more diving experience, you may become better at:
A beginner may inflate the BCD, rise too far, dump too much air, sink, kick upward and inflate again. Every correction requires movement and attention.
An experienced diver often makes much smaller adjustments. They use their breathing for fine buoyancy control, remain streamlined and allow the water to carry them during a drift dive.
The result is less physical work and usually lower gas consumption.
Making ten dives during one holiday can produce more improvement than completing ten dives over several years.
When divers take long breaks, each new trip may begin with a period of readjustment. They must become comfortable with the equipment, buoyancy, breathing and underwater environment again.
Regular diving helps these skills become automatic.
This does not mean you need hundreds of dives before you can become efficient. Some divers develop excellent control quickly, particularly when they receive focused coaching. Others need more time.
The number in your logbook is less important than what you practise during those dives.
Simply making more dives while repeating the same inefficient habits may produce only limited improvement. Experience is most valuable when it is combined with feedback and purposeful practice.
One of the best ways to improve air consumption is to improve buoyancy.
A diver who is correctly weighted and neutrally buoyant does not need to kick constantly to remain at the same depth. They do not need to inflate and deflate the BCD repeatedly, and they are less likely to contact the bottom or reef.
Good buoyancy reduces unnecessary effort.
It also helps the diver become more relaxed because they feel in control of their position. Less effort and less stress can both contribute to more efficient breathing.
Poor buoyancy can increase gas use in several ways:
Good buoyancy is therefore not only about looking comfortable underwater. It affects safety, gas efficiency and environmental behaviour.
The SSI Perfect Buoyancy specialty is designed for divers who want focused coaching rather than hoping their buoyancy will improve automatically over time.
During the specialty, divers can work on:
SSI recommends the Perfect Buoyancy specialty for divers who want additional buoyancy knowledge and repeated practical exercises.[6]
At Oceans 5 Gili Air, buoyancy is closely connected to our conservation philosophy. A diver can understand marine conservation, avoid deliberately touching coral and participate in beach clean-ups—but without adequate buoyancy control, their fins or equipment may still damage the reef.
Perfect buoyancy makes responsible intentions effective underwater.
It can also make diving feel completely different. Instead of constantly correcting your position, you can relax, observe marine life and move with much less effort.
For many divers, improved air consumption becomes a natural result of that increased control.
It should not be the only reason to complete the specialty, but it can be a valuable benefit.
Trim describes a diver’s position in the water.
A diver in a balanced horizontal position presents a smaller surface area in the direction of travel. This reduces resistance and makes movement more efficient.
A diver in a vertical or head-up position creates more drag. They may need to kick harder to move forward, and part of every kick pushes them upward rather than forward. They then release air or stop kicking, begin to sink and repeat the process.
Equipment positioning also matters. Hanging gauges, alternate air sources and accessories create drag and can damage the reef.
Improving trim does not require a single equipment configuration for every diver. Body shape, exposure protection, cylinder type and equipment choices all affect balance. Moving weights or adjusting cylinder position can make a significant difference.
This is another advantage of professional buoyancy coaching: the instructor can observe what is happening rather than expecting the diver to diagnose their own position underwater.
Scuba diving is not a race.
Swimming quickly usually means:
Around the Gili Islands, many dives are drift dives. When conditions are suitable, the current does much of the work. Divers can maintain position, avoid unnecessary finning and allow the reef to pass beneath them.
Stay behind or beside the guide as instructed during the briefing. Do not repeatedly swim ahead and then fight the current to return.
A slower diver often sees more.
Some divers feel embarrassed to tell the guide that they have used more air than the rest of the group. They may display the wrong number, wait too long to report their pressure or hope that nobody asks again.
This creates a safety risk.
Your Divemaster needs accurate information to decide:
Using air faster is not a problem. Hiding it is.
At Oceans 5, divers are divided into small groups with a maximum of four certified divers per guide. Grouping divers by experience, air consumption and interests makes it easier to create a pace and profile appropriate for everyone.
Tell your guide before the dive if you know that you normally consume gas quickly. This information helps us plan; it does not create a negative judgment.
Training and experience can improve efficiency, but divers do not all have the same physical gas requirements.
A larger, experienced diver may naturally consume more air than a smaller buddy. Even with excellent buoyancy and relaxed breathing, the difference may remain.
In this situation, using a larger cylinder can make sense.
Oceans 5 offers 15-litre tanks for divers who would benefit from additional gas. The current supplement is IDR 50,000 per tank.
A larger cylinder is not a substitute for monitoring gas or following the dive plan. It simply provides a larger supply and can help buddy teams with different consumption rates enjoy a similar dive time.
There is no shame in choosing the cylinder that best matches your needs.
Good general fitness can support relaxed diving, especially in current or when surface conditions require additional effort.
However, the relationship between fitness and air consumption is not always simple. A highly muscular athlete may still consume more gas than a smaller, less athletic diver. Anxiety, technique, depth and buoyancy can have a greater influence during a particular dive.
Useful areas of fitness for divers include:
The goal is not to become the strongest person on the boat. It is to avoid unnecessary exhaustion and remain comfortable within your personal limits.
If conditions require more effort than you are comfortable with, inform the guide. Changing the site or dive plan is better than trying to prove that you can keep up.
If you want to use your gas more efficiently, focus on the complete dive rather than only your breathing.
Progress is easier to see when you compare similar dives over time.
There is nothing wrong with wanting to improve your air consumption.
Using gas more efficiently can lead to more relaxed dives, longer bottom times within safe limits and better compatibility with your buddy. It can also reflect improvements in buoyancy, trim and overall comfort.
But pressure remaining at the end of a dive does not define the quality of the diver.
A diver who surfaces with 70 bar after following the plan and communicating honestly has completed a better dive than someone who surfaces with 100 bar after holding their breath, hiding their pressure or ignoring their buddy.
More diving can help. Regular experience allows you to become calmer, reduce unnecessary movements and develop better awareness.
Focused training can help even more. The SSI Perfect Buoyancy specialty gives you the opportunity to work directly on weighting, trim, control and efficient movement with professional feedback.
At Oceans 5 Gili Air, we would rather help you become comfortable and controlled than tell you simply to “breathe less.”
Relax. Maintain your buoyancy. Stay close to your buddy. Report your pressure honestly and enjoy the dive.
Your air consumption will often improve naturally as the rest of your diving improves.
Yes. Body size, depth, workload, stress, experience, fitness and cylinder size can all affect gas consumption. Two divers should not expect to finish every dive with identical pressure.
No. It may indicate areas that can be improved, such as buoyancy or relaxation, but some people naturally require more breathing gas. Safe monitoring and honest communication are more important than having the lowest consumption.
Dive regularly, improve buoyancy and trim, slow down, avoid unnecessary movement, remain streamlined and breathe continuously in a relaxed rhythm. Do not restrict your breathing.
It often does. Regular diving can increase comfort, reduce stress and make equipment use, buoyancy and movement more automatic. Focused practice and instructor feedback usually produce better results than merely collecting dives.
Yes. The specialty focuses on weighting, neutral buoyancy, trim, streamlining and efficient underwater movement. These skills can reduce unnecessary effort and may therefore improve air consumption.
No. Holding or skip-breathing can contribute to carbon-dioxide accumulation. Holding your breath during an ascent can cause serious lung injury. Maintain continuous, relaxed breathing.
Yes. The regulator supplies gas at the surrounding pressure. As depth and pressure increase, each breath removes more gas from the cylinder.
Report your pressure whenever requested and at the limits agreed during the briefing. Never delay or give an inaccurate reading because you feel embarrassed.
Yes. Oceans 5 offers 15-litre tanks for an additional IDR 50,000 per tank. Tell the team in advance so the correct equipment can be prepared.
No. Nitrox changes the proportion of oxygen and nitrogen in the cylinder, but it does not significantly change how quickly you breathe the gas. Nitrox can offer decompression-related benefits when used correctly, but it is not a solution for high gas consumption.[7]
The 27–28 August TCN survey and the announced beach clearance may mark a turning point—but only lasting enforcement will protect the marine park Gili Air, Gili Meno and Gili Trawangan are not simply three popular holiday islands. Together with their surrounding waters, they form Gili …
