We set up the equipment for the class, tank, BCD, weight belt, regulator, mask, snorkel & fins. Morgan was pretty excited about taking her class and our PADI instructor Pako started out by covering the basic principles that allow pretty much anyone to get out there & dive!
The pool class takes about 45 minutes to an hour and covers basic dive theory, proper use of equipment and basic exercises that help each diver feel comfortable and confident when they're out there diving in the ocean.
Once all of the equipment was set up, Morgan was ready to hop in the pool. Ideal pools for scuba classes go from shallow to about 10-12 feet deep so you can start in water that's up to your waist and cover all the practice exercises, then head to the deep end to practice what you've learned.
The first part of dive theory that is covered in our Discovery Dive program is understanding how pressure affects your body as you descend from the water's surface. You can imagine what happens to a balloon that is filled with air when you start to submerge it underwater ... it starts to shrink in size. The same principal can be applied to the human body with relation to air spaces such as your sinuses or ear cavities.
When you dive, you may feel a slight pressure on your ear spaces like when you're in an airplane or when driving up a mountain side. To relieve the pressure you simply compensate the air spaces by gently blowing air through pinched nostrils. Some people are able to compensate by simply swallowing or moving their jaw around.
With Pako's help, Morgan went through the intial exercises of checking the equipment, clearing the mask & regulator (which is the hose & mouthpiece that allows you to breathe underwater) and practicing the signals for communicating underwater. These exercises are designed for first timers and beginners and are an excellent way to become a confident scuba dive enthusiast.
Practicing certain skills like clearing the mask or recouperating the regulator make diving a more fun and rewarding experience. They also allow a diver to focus less on their equipment and more on the amazing underwater life that surrounds them!
Within a short time in the pool, Morgan was already feeling comfortable with the dive equipment and had experimented with the initial exercises. She was soon ready to take a lap to the deep end! Here she gives the diver "OK" sign which means that everything is A-OK.
The best part about scuba diving is being able to communicate underwater without even having to speak. Divers have special hand signals that they can use to communicate with their dive guide (Divemaster) ensuring maximum enjoyment of each dive.
