Scuba Declassified

In the year 2016, Typhoons made a late appearance in Japan. It ranked as the second-latest occurrence in recorded statistics for this country.While a lack of typhoon is much to the delight of divers, this extended absence led to a rise in sea temperature. This usually causes widespread coral bleaching events.In 2017, we saw the […]

Let’s dive in, full throttle!If you’re planning many exhilarating dives annually, this can lead to hefty gear rental fees…But, if we think beyond just getting a certification and a few dives sessions, there’s a smart financial move: invest in your own gear. This not only lets you explore whenever you want, but also saves you […]

From your early days of scuba diving, you may soon experience a myriad of brightly colorful fish especially when visiting tropical diving destinations around the globe. While diving deeper and deeper you will encounter and see different species.For example, when reaching around 100 feet (30 meters) you may see the one shown in this picture below:”Wow, […]

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, but rather […]

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 though it is […]

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 distribute the weight […]

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 trigger […]

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 but recommended […]

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 […]
