SSI Open Water Diver (Bali)

As you descend into the water, the pressure around you increases. Pressure is a key concept of diving as you are subjected to it at depth. In this course, you will learn why it happens and the effects of this increasing pressure with relative to density and volume. This concept can provide you with explanation to some of the magically wonders of the sea and your body. For example, salt water vs fresh water diving and ear popping with pressure.

The diving equipment is essential for scuba diving, as it allows you to breathe underwater and move more efficiently through the water. Learn about the different systems that your scuba equipment is made up of and its functions, as well as how to properly maintain your equipment.

The Total Diving System that enables you to be underwater, is made up of:
– Delivery System
– Buoyancy System
– Information System

Breathing air at depth as you scuba dive, has a profound effect on the body. The gas is typically a mixture of oxygen and nitrogen. The oxygen is used by the body to maintain normal metabolism. The nitrogen, however, can have a narcotic effect on the body at high concentrations.

In this Topic, you will learn about,
– Your Respiratory System and give an example of how gas could enter the bloodstream.
– What air is made out of
– Partial Pressure
– Effects of breathing gas at depth
– Identifying the 4 possible lung overexpansion injuries, symptoms, treatment and prevention
– Identifying the different diving illnesses, understanding the cause, symptoms, treatment and prevention

When scuba diving, it is always best to have a buddy. This is someone who you can rely on and who will help you if you run into any problems. Before each dive, it is important to plan your dive. This includes deciding where you want to go, what you want to see, and how long you want to stay down.

In this Topic, you will learn about,
– Importance of diving with a buddy
– How to plan and execute your dives
– The Dive Computer and how it helps you underwater
– Understanding surface intervals and repetitive dives with relative to nitrogen absorption
– Understanding No-Decompression Limit (NDL)
– How to navigate and orientate yourself underwater

The ocean is a vast and beautiful place, but it is also fragile. As divers, we have a responsibility to protect it. Learn about why the world’s ocean waters are crucial to sustaining life on land, how coral reefs are forms, why you should avoid any contact with corals or marine life underwater, common causes of diving injury and how you can contribute to protecting the ocean while diving.

When diving, it is important to be aware of the potential for emergencies and to know how to handle them. In this topic you will learn,

– Factors that lead to a panic situation and how you can avoid it
– What you should do in response to a panicked diver on surface and at depth
– 3 possible responses to an Out of Air Emergency and its conditions
