Ultimately, the choice depends on the dive objective, environment, and diver competence. A wreck penetration at 50 metres with tight swim-throughs may favor the self-contained twinset, while an open-water trimix dive with deco stops may be better served by a modular stage approach.

Golden rules of scuba diving

by Robert Diaz on Jun 05, 2025

Scuba diving is more than just a sport or a hobby—it’s an incredible opportunity to immerse yourself in an entirely different world.  Beneath the surface of the water lies an environment filled with astonishing marine life, vibrant coral reefs, dramatic shipwrecks, and seascapes that few people will ever get to experience first-hand. However, with this privilege comes responsibility. Every time you strap on your gear and take that giant stride into the ocean, you are placing your safety, your wellbeing, and the health of the underwater ecosystem into your own hands. That’s why the Golden Rules of Scuba Diving are not simply guidelines—they are fundamental principles that every diver, regardless of experience, should understand and follow without exception. These rules have been developed over decades of diving practice, safety research, and environmental observation. They are designed to keep you safe, ensure a smooth and enjoyable dive, protect your fellow divers, and preserve the delicate underwater world for future generations. For new divers, these rules form the building blocks of safe diving practice. For experienced divers, they serve as constant reminders that complacency has no place beneath the surface. From monitoring your air supply and never diving beyond your training limits, to respecting marine life and perfecting buoyancy control, each rule plays a critical role in shaping a responsible and skilled diver. Ignoring these core principles can lead not only to dangerous situations but can also harm the fragile marine environments that so many divers work hard to protect. The ocean is not our natural habitat—we are visitors in this underwater world. Acting with care, caution, and respect ensures that we enjoy its wonders without leaving a damaging footprint. In this guide, we will explore the key Golden Rules of Scuba Diving that every diver should know and live by. Whether you are preparing for your first dive or have hundreds of dives logged, these rules are your passport to safer, more rewarding underwater adventures. Here are ten essential safety principles every diver should follow to ensure a safe and enjoyable experience underwater. 1. Always Dive with a Buddy: Diving with a buddy is a critical safety measure. In case of an emergency, having a partner allows you to assist each other with equipment, air supply, or navigation issues.2. Plan Your Dive and Dive Your Plan: Before entering the water, make a detailed dive plan, including your depth, duration, and emergency procedures. Stick to the plan to avoid unexpected risks.3. Check Your Gear: Always perform a pre-dive equipment check (often called a "buddy check") to ensure your scuba gear, especially your regulator, buoyancy control device (BCD), and gauges, is functioning properly.4. Monitor Your Air Supply: Regularly check your air gauge to ensure you have sufficient air throughout the dive and maintain enough reserve to safely ascend and complete a safety stop.5. Ascend Slowly and Safely: A controlled ascent is vital to prevent decompression sickness ("the bends"). Always ascend at a safe rate (no faster than 9 metres per minute) and make a safety stop at 5 metres for 3-5 minutes.6. Equalise Early and Often: Equalise your ears and mask frequently during descent to avoid barotrauma (pressure-related injuries). Never force equalisation; if you are unable to equalise, stop your descent and ascend if needed.7. Within Your Limits: Dive within your training, experience, and comfort level. Avoid diving deeper or under more challenging conditions than what you are certified and prepared for.8. Maintain Good Buoyancy: Proper buoyancy control is key to safe diving. It helps prevent accidental collisions with the seabed, coral, or marine life and reduces fatigue from unnecessary effort.9. Be Aware of Your Surroundings: Keep track of your dive location, your buddy, your depth, and potential hazards like currents, boat traffic, or marine life. Stay alert to avoid dangerous situations.10. Respect the Underwater Environment: Avoid touching or disturbing marine life, corals, or fragile underwater ecosystems. Not only is this for environmental conservation, but some creatures can be dangerous if disturbed.These safety principles form the foundation for safe scuba diving, helping divers minimise risks and enjoy the underwater world responsibly.

Ten very good reasons for wearing a dry suit all year round.

by Robert Diaz on Oct 15, 2024

Wearing a dry suit whilst scuba diving offers a range of benefits, making it a valuable investment for year-round diving. Here are 10 excellent reasons to wear a dry suit:1. Thermal Protection: A dry suit provides superior insulation in cold water, keeping you warm even in icy temperatures, allowing for diving in cold regions or during winter.2. Extended Dive Time: Staying warm helps prevent hypothermia, enabling longer dives without the discomfort or risk associated with cold water exposure.3. Diving in Various Conditions: A dry suit allows you to dive comfortably in a wide range of environments, from frigid waters to temperate seas, expanding your diving opportunities.4. Year-Round Diving: With a dry suit, you can dive year-round regardless of seasonal temperature changes, offering flexibility for continuous diving activities.5. Control Over Insulation: You can adjust the undergarments worn beneath the dry suit to increase or decrease insulation depending on the water temperature, providing versatility.6. Improved Buoyancy: Dry suits offer added buoyancy control, which helps divers achieve better stability in the water. This is particularly useful in cold waters where thick neoprene wetsuits may be restrictive.7. Enhanced Comfort: By keeping you dry, a dry suit minimises the discomfort of cold water contact, allowing for more comfortable and enjoyable dives.8. Protecting Skin from Harsh Elements: A dry suit offers full-body protection against harmful marine life, pollutants, and rough underwater environments like rocks, which can cause cuts or stings.9. Increased Safety: Cold water can lead to loss of coordination and increased risk of accidents. A dry suit keeps your core body temperature stable, reducing the risk of cold-related accidents.10. Easier Surface Intervals: Staying dry between dives is more comfortable during surface intervals, especially in windy or cold conditions, reducing the likelihood of feeling chilled before your next dive.A dry suit provides essential protection and flexibility for diving in diverse conditions, making it a smart choice for divers who want to dive year-round.

Your first extended range dive.

by Robert Diaz on Mar 26, 2024

Exploring the fascinating underwater world is an exhilarating experience that leaves divers yearning for more. If you've conquered recreational diving and are now ready to embark on your first extended range dive, you're in for a treat. Extended range diving allows you to dive deeper and stay underwater longer, offering the opportunity to witness breathtaking marine life and dive sites. Let's remember the importance of protecting our precious Central Coast and its fragile marine ecosystems. Here are some essential steps to prepare for your first extended range dive. 1. Enhance Your Skills and Knowledge: Extended range diving comes with its own set of challenges and risks. Before attempting such dives, it is crucial to enhance your skills and knowledge. Consider enrolling in specialty courses such as deep diving, wreck diving, Horizon semi closed rebreather or enriched air nitrox diving to gain expertise and confidence.2. Selecting the Right Equipment:Choosing the appropriate equipment is vital for an extended range dive. Invest in high-quality gear, including a reliable dive computer with advanced decompression capabilities, redundant gas supply (twin tanks or side mount configuration), Semi closed rebreather, and suitable exposure protection to handle the colder temperatures at greater depths. Make sure all your equipment is properly maintained and serviced before each dive.3. Plan Your Dive:Proper planning is crucial for any dive, and it becomes even more critical for extended range dives. Research and choose a dive site that suits your skill level and interests. Study the site's depth, current conditions, and any potential hazards. Create a detailed dive plan that includes gas management, decompression stops, and emergency procedures. Consult experienced divers or local dive centres for valuable insights and advice.5. Physical Fitness and Mental Preparation: Extended range diving demands physical fitness and mental preparedness. Engage in regular exercise, focusing on cardiovascular endurance and muscle strength. Strengthen your core and improve flexibility through activities like yoga or Pilates. Mental preparation involves developing a calm and focused mindset, as extended range dives can be physically and mentally demanding. Practice meditation or visualisation techniques to help maintain composure underwater.6. Dive with a Buddy and Maintain Communication: Never embark on an extended range dive alone. Always dive with a buddy who is experienced and trained in extended range diving techniques. Establish clear communication signals and ensure you both understand each other's limitations and emergency procedures. Regularly check in with your buddy during the dive to maintain situational awareness and provide mutual support.Protecting Our Central Coast: As we gear up for our thrilling extended range dives, it is crucial to remember our responsibility towards preserving our natural environment. The central coast is home to diverse marine ecosystems that are vulnerable to human impact. Let's commit to being responsible divers by following established guidelines, respecting marine life, and avoiding damage to local reefs and other delicate habitats. Engage in local beach cleanups, support marine conservation organisations, and spread awareness about the importance of protecting our central coast.Embarking on your first extended range dive is an exciting milestone in your diving journey. By focusing on skill development, equipment selection, planning, physical fitness, and dive buddy communication, you can ensure a safe and memorable experience. Remember to dive responsibly and join the collective effort to safeguard our Central Coasts' marine ecosystems. Let's explore the depths with awe and respect, leaving behind a legacy of conservation for future generations of divers to enjoy. Happy diving, and let's protect our beautiful Central Coast underwater together!
