Basics of Scuba Diving

When you go scuba diving the first time, you will be faced with a unique problem and that is trying to go down below the surface of the water to your desired depth. There will be a natural tendency to float to the surface, an issue that you have to solve with ballast weights. The crucial question is that you should have ballast just right to be safe and function well at all depths. Less will push you to the surface; more will make you struggle to come up. To achieve the preferred goal, the weight of the ballast should be accurate and precise enough to match your requirements.

The first step that you will be taught is to be neutrally buoyant at 15 feet depth with an empty BC and a near empty oxygen tank. The rule of thumb and the benchmark from where all extra adjustments will start is carrying 10% of body weight in lead. Another method at stabilisation that you can try is to wear full scuba gear and carry the weight that would enable you to float at eye level with the surface of the water.

Learning scuba diving is not a complicated affair and you can do well to take help of online tutorials to know the initial steps, at least of maintaining the required buoyancy. But then if you are really enthusiastic about it get a trainer to help you out. There are risks involved so if you are practicing off the coast of Victoria, Australia, it is advisable to first contact Melbourne employment lawyers to know the liability of the trainer in case any harm should befall you. One of the expert law firms in this field is PB Law.

Coming to the matter of buoyancy, here are a few steps that you should take.

Calculation for your body – Find out the weight that will make your body neutral. Take few weights into the water simply wearing a swimsuit. If you can stand motionless with half a breath and go under when you exhale, that is the right ballast for you.

Calculate for your exposure suit – Repeat the first step but this time wearing your exposure suit. Get the weight required now to float neutral and deduct from that of the first step. This is the buoyancy weight of your exposure suit.

Calculate buoyancy of the BC – You can do so by kneading out all the air bubbles from the padding of the BC and then add weights till you find the BC hanging neutral in the water.

Once you have found out the weights required for attaining buoyancy and hanging at a neutral depth with full gear on, you can start adding ballast to go down to required depths.
