The Risks of Diving

Most sharks, such as this small white tip reef shark, are docile in nature and rarely a threat to divers.

Your equipment will include a pressure gauge that allows you to check your air supply at any time during the dive.
Common Misconceptions
Scuba diving is not without risk. However, the fears that most new divers face are based on misconceptions and exaggerations. The following are some common examples.

"Divers are vulnerable to shark attacks"
It's true that sharks have attacked divers, but attacks are rare and the risk is minimal. Most attacks occur at the surface, so you are at a higher risk when swimming or surfing. Most sharks pose no danger to humans, and normally flee the area when they hear your bubbles.

"It's easy to run out of air"
Divers now carry pressure gauges that indicate the remaining pressure inside their cylinders. This allows divers to monitor their air supply during the dive. If you do run out of air, you can breathe from your buddy's air supply by using an alternate air source, which is standard equipment.
