One of the first concerns many qualified divers have is buoyancy and their air consumption. As an Instructor, skipper and Divemaster I am often reminded of my own concerns when I started diving. Don’t envy the diver on the boat staying down the longest on the smallest cylinder. Dive often, enhance your training, hone your skills and soon you will be that diver, first in and last out, with air to spare.
It makes no difference who your Instructor was, which certification agency you obtained your qualification from or where you are diving. All divers are taught the basics of diving during their initial training. However, the duration of your qualifying dives has a huge impact on your level of competency at the end of your training.
If you have done four, or five in some instances, short twenty minute dives (the minimum for PADI) and – let’ s presume – you spent two hours in the water during your confined water training then your total bottom time will be less than four hours. However if your qualifying dives were 50 minutes each it will be the case that your total bottom time when you’re newly qualified is a lot more.
Some people take to diving instantly and do not find any aspect of the training intimidating and within two hours of getting into the water they are relaxed, have good buoyancy and controlled breathing. For others it is a little harder coming to terms with the heavy gear, good buoyancy control seems to be a distant dream and managing to get 30 minutes on a 12 litre cylinder in shallow water is out of the question.
With bottom time comes perfection. This involves becoming comfortable with your gear so you instinctively find your pressure gauge, being correctly weighted (a huge factor in air consumption), being warm, and moving slowly with the correct profile. All of this improves air consumption dramatically.
Another important factor is confidence. Diving beyond your ability and training, doing a dive you feel you should rather not be doing are huge ”gas guzzling” factors so don’t do that deep dive to a wreck because you feel you can or think you should, do it when you know you can and really want to.
The learning curve for a diver is steep and for me the most rewarding aspect of teaching diving is to watch and be a part of a students initial flapping around in the water like a fish out of the water, to becoming relaxed, calm and confident, and watching them grow into a competent diver in such a short period of time.
