Top Sidemount Diving Koh Tao Guide & Tips
Why Koh Tao is Ideal for Sidemount Technical Diving
Koh Tao, a small island in Thailand, is famous for its beautiful underwater landscapes and rich marine biodiversity. It’s a paradise for divers of all levels, but it’s especially perfect for sidemount diving. The island’s clear waters, rich sea life, and many dive sites provide a unique diving experience that keeps enthusiasts coming back.
Koh Tao’s sidemount diving offers divers the chance to delve into more demanding environments and offers more flexibility. La Bombona Diving, among the island’s leading diving schools, offer excellent training and equipment, guaranteeing a safe and exciting experience.
Essential Information Before Diving
Prior to planning your sidemount diving journey in Koh Tao, there are a couple of crucial things you must be aware of. First and foremost, make sure you have the right certification. The Sidemount Diver course is an excellent place to begin, and it comprises four open water dives to help you develop your abilities.
In addition to obtaining the necessary certification, every diver has to comprehend the advantages and disadvantages of sidemount diving. The equipment configuration differs from standard scuba diving, and handling two tanks necessitates careful practice and accuracy. Nonetheless, the benefits, such as better buoyancy control and longer dive durations, make diving koh tao a worthwhile endeavor.
Why Sidemount Diving is Beneficial
Better Diver Flexibility and Movement
Sidemount scuba provides divers with better flexibility and movement, which is one of its main advantages. The tanks are mounted on the sides instead of the back, allowing divers to move more freely and get into tighter spaces. This is especially helpful for exploring caves, wrecks, and other small areas.
In addition, the sidemount configuration alleviates pressure on your back, making it a more comfortable choice for longer dives. This arrangement provides improved trim and balance, which enhances your overall scuba experience.
Improved Safety and Backup
Sidemount diving also improves safety by providing a backup. By carrying two tanks, divers have an independent air supply in case of equipment failure. This backup is a major advantage, especially in technical diving situations where safety is critical.
Moreover, the sidemount configuration makes managing and monitoring gas simpler. Divers can alternate between tanks to maintain an even gas supply, which lowers the likelihood of suddenly running out of air.
Longer Scuba Dive Time
Sidemount diving offers the unique advantage of longer dive times. This is because divers are equipped with two tanks, providing a larger supply of gas. This is especially useful when diving in deeper or more intricate dive sites that require more time underwater.
For example, sidemount divers can devote more time to watching sea creatures, exploring underwater structures, or making their way through complex cave systems. The increased bottom time improves the overall diving experience, making each dive more fulfilling.
Must-Have Sidemount Diving Gear
Sidemount Harness and BCD
Your sidemount harness and buoyancy control device (BCD) are the key parts of your diving gear. The harness needs to fit well and give enough support for the tanks. The BCD, which is made especially for sidemount diving, lets you control your buoyancy better and streamline.
When it comes to selecting a harness and BCD, you should take into account comfort, adjustability, and durability. A properly fitted harness and BCD can make your diving experience more enjoyable and safer.
Regulators and Long Hoses
The regulators are another vital gear for sidemount diving. You will require two regulators, one for each cylinder. It’s crucial to select top-notch regulators that are dependable and straightforward to use.
-
Main regulator: This is the regulator that connects to the tank you’ll be breathing from initially. It usually has a longer hose for easy sharing in emergency situations.
-
Backup regulator: This is the regulator that connects to the second tank and is used as a backup. It should also be easily accessible and functional.
The correct regulators and long hoses are essential for a smooth and safe diving experience.
Correct Tank and Mounting Methods
Correct tank and mounting methods are crucial for any diver considering sidemount. In a sidemount configuration, the tanks are mounted along the sides, not on the back. This arrangement provides improved balance and easier access to valves and regulators.
The type of diving you plan to do should influence your choice of tanks. Aluminum tanks are lighter and easier to manage, making them a great choice for recreational dives. However, steel tanks are stronger and offer more buoyancy, which is a plus for technical dives.
The way you mount your tanks is also crucial. Make sure that the tanks are firmly secured to the harness and placed in a way that provides the best balance. Before you go out into the open water, practice putting the tanks on and taking them off in a controlled setting.
The Role of Dive Computers
Dive computers are essential tools for sidemount diving. They keep track of a diver’s depth, time, and gas consumption, allowing for a safe and efficient dive. A high-quality dive computer will also monitor your decompression status, offering instant information to prevent decompression sickness. For more information on sidemount diving, check out the sidemount diver course at La Bombona Diving.
When you’re in the market for a dive computer, you should prioritize features like the ability to manage multiple gases, displays that are easy to read, and interfaces that are easy to navigate. A reliable dive computer isn’t just a tool—it’s an investment in your safety and it can significantly improve your diving experience.
