Remember transitioning from the basic masks we started with when we first received our scuba diving licenses and moving up to even more stylish and impressive masks…?Initially, when we got our licenses, we didn’t possess much, but as we saw others with attractive masks, the desire grew in us…Usually, a year after obtaining a license, […]

This is the most asked question by non-divers and tourists. It even happens during the preparation phase at the beach or after returning from a dive. People might have the impression that the tank isn’t very large… But, inside the Cylinder, there is air compressed to 200 times the normal pressure. It’s not pure oxygen, […]

For those unfamiliar with diving, the idea of venturing into the sea late at night might be challenging. For divers, encountering these radiant creatures is a cherished experience. Scenes like these become treasured memories!Though it might not happen every day, seeing glowing plankton is actually quite common. It is no exaggeration to say that even […]

When it comes to adjusting buoyancy underwater, two important things come to the rescue. One is the buoyancy compensator (BC) and the other is your lungs.  However, an appropriate amount of weight is important to achieve comfortable neutral buoyancy. Yet, it’s not just about getting the weight right; there’s more to consider. The way you […]

DECO, short for decompression, plays a crucial role in ensuring diving safety. As we discussed in this article, standard dives operate under the assumption of “no-decompression required”. It allows divers to explore without the need for Decompression stops. However, venturing beyond the allocated time for a no-decompression dive – NDL, No decompression Limit – will […]

First, let me ask you a quick question:「Does Recreational Scuba Diving include decompression stops?」Well, the correct answer is actually mostly “No.” However, your class may have included the practice of a Safety Stop. This Safety Stop is a simulated decompression stop at approximately 15 feet (5m) for 2 to 3 minutes and is not required […]

Have you ever thought about how pressure and density impact our lives? From morning to night, they play a significant role. Interestingly, in our daily routines, we rarely consider density. But, Scuba Diving will change that! This article explores the relationship of pressure and density of a gas such as air, making it easy for […]

Have you ever noticed that things look bigger when you see them underwater? Imagine you are at a cool café. When you’re given a glass of water with a straw, you might observe that the part of the straw submerged in water looks larger than the part above the water.  Another example is when you’re […]

Hey, fellow divers! We all want to make the most of our time underwater, right? Picture this: You’re diving with your team, and oops, you start feeling a little guilty because your air supply is running low compared to the others. It happens! We will talk about the smart ways to manage your air in […]

When it comes to scuba diving, grasping the concept of neutral buoyancy is crucial. Yet, achieving neutral buoyancy is not a one-time accomplishment. It requires continuous adjustments to the air volume inside the buoyancy compensator (BC) based on the depth. Why is it necessary to fine-tune the air volume within the BC as per the […]
