[Entry] [Descent] [Neutral Buoyancy] [Swimming] [Ascent] [Exit]
This is weightlessness that you first experience while diving, when you are neither floating nor sinking. The way you enjoy your dives will change significantly, mainly due to how you breathe. The amount of weights you put on will also change because of differences in tanks and wetsuits. Please get the hang of neutral buoyancy and learn the necesssary skills.
The image on land is important when it comes to neutral buoyancy. Because your wetsuit is buoyant in addition to your lungs, you are extra buoyant at the surface of the water, which is why we wear weight belts to descend. In the water, on the premise of achieving the right buoyancy where you are neither floating nor sinking, you will float when breathing in and sink when breathing out. Please try to picture this in your mind.
Check point!
Breathing during diving must be deep and slow. Remember that there is a time lag, not that you will float or sink immediately upon breathing.
Establishing the correct weights will change depending on your gear, weights and tanks. On the Similan Islands, we usually use 0.8kg weights and 12 litre aluminium tanks. An aluminium tank feels heavy at first but as you use up the air it becomes quite light so please keep this in mind when deciding on your weight.
The waters around the Similan Islands are extremely salty and it is easy to float, so during your check dive, please make sure that you have a slightly heavier amount of weights than a usual dive and maintain neutral buoyancy.
During diving, it is best to breathe slowly and deeply. Neutral buoyancy is generally achieved by breathing but if you are floating up when you breath out, you should dump the air in your BCD and get rid of excess buoyancy. If, on the other hand, you are sinking despite breathing in, add air to your BC to become more buoyant.
During diving, it is best to breathe slowly and deeply. If you can master this, your diving skills will greatly improve.
■ A Word of Advice Your breathing is the most important during diving. In order to breathe deeply and slowly, if you can breathe in through your regulator as if sucking through a straw with pursed lips, it will greatly save energy and air. The Similan Islands are home to plenty of sites with dynamic topography such as rocks piled on top of one another, so please do your best to acquire neutral buoyancy and enjoy your diving.
