GETTING THE HANG OF BUOYANCY CONTROL
Buoyancy and buoyancy control are scuba divers most important concepts to understand and master in order to dive safely and enhance enjoyment underwater.Unfortunately, buoyancy isn’t that easy to grasp for most new divers, and is often being neglected during the short period of time it takes to become a certified scuba diver.As scuba instructors, we know how hard it is sometimes to understand this concept and fully commit to it throughout the dive, but we also know the benefits and share the enjoyment of those who finally got the hang of it and now, for the first time, truly appreciate scuba diving.
The buoyancy control workshop is intended to deliver simple and useful information to help scuba divers at all levels improve their buoyancy control.
here are the different aspects we will discuss:
Buoyancy control theory, background and terminology:
On the open water course, you learn some basic terminology and are introduced to the theory behind buoyancy control. Sometimes during these courses people tend to rush things up, mostly cause their on holidays, or they think they can do without. Here. We’ll try and simplify things, and shine some light on the theory of buoyancy:
- Negative, positive and neutral buoyancy.
- Archimedes’s Law
- Pressure, volume depth and density.
Once you understand the basic theory behind buoyancy, you may also want to know what difference it makes, and what will you get from putting all that effort into it. In order to really want to improve your skills and better understand buoyancy and it’s affects on scuba diving, we need to understand why buoyancy control?
There are several factors that affect our buoyancy control. These factors determine the need for changes in weights which we apply during pre-dive preparations, and also affect our buoyancy underwater, which leads us to changing the volume of air we hold in our BCD or Dry Suit in order to regain neutral buoyancy during the dive.
Many dive leaders, especially scuba instructor teaching introductory scuba courses such as the Open Water course, or Discover Scuba Diving courses, will often overweight their students. The main idea is that understanding buoyancy control takes some time and practice, and although it may be harder to do when carrying extra weights with you, it gives the instructor greater control over the diver and the group, as scuba instructors prefer you close to them than “popping” to the surface, struggling with your buoyancy.
As a result, some divers never tried to dive properly weighted which is easier and overall safer, once you understand buoyancy control. Learn how to estimate the right amount of weights through this simple step by step guide to make your dive experience better, longer and safer.
The practical buoyancy control section will introduce you to various tips:
- How to move properly underwater
- Ascent and descent techniques,
- How to estimate the right amount of weights for scuba
- How to perform a buoyancy check
- How to master hovering
- How to master fin pivot
- Buoyancy control and breathing
- How to use the BCD correctly.
Finally, it all comes down to practice. Most scuba divers won’t get buoyancy at once. Sadly, I must say most Open Water Graduates will have some understanding of it but rarely are perfect scuba divers at that time. The toll on the marine environment and the risks the divers take on themselves is huge, and often forgotten.
Make sure you get proper training, and keep your skill level up to date. The more you dive the easier it gets, and the better you become.
We’ll be happy to answer any questions and follow any suggestions.
