I came back to the dive centre a week later. Now I had signed up to the course, it was time to learn some serious techniques and apply them in the water.
I was eager to get back in the water, but before I could do so, I first had to prove my knowledge. Since my last dive, I had been instructed to read the first two chapters of the Open Water Diver manual, and answer the questions.
We went through the questions and answered and and that I got wrong were explained carefully. I then had to complete two questionnaires independently (one for each chapter)
We began with all the usual pre-dive checks: equipment, safety, signs, and a buddy check. Once everything was ready, we got into our wet suits – this is always done after the safety checks to prevent excessive overheating.
We then plunged into the water, the same way as before, and the training began.
First up, I had to take off my mask completely for 10 seconds, put it back on and clear all of the seawater. Then, my oxygen was turned off and I had to use my instructor’s “octopus” or spare regulator. This was scary at first, but it soon proved to be no problem. I knew that learning these skills could one day save my life.
I also had to attain neutral buoyancy. After some initial trouble with deciding which weights I needed, I eventually accomplished this. You can tell when you have neutral buoyancy when you float slightly when breathing in and sink again when breathing out.
Other skills that are covered in the second and third confined water dive are:
- Five point descent
- Fixing a loose cylinder band
- Five point ascent
- Post dive care
Once I was back in my surface attire, I booked my next two diving lessons. My training would continue next week.
