To become a certified diver, you must complete a training course and then earn a scuba diving certification from a certifying body. PADI, Scuba Diving International or SSI are the certifying bodies for scuba diving. Other certifying bodies exist, like SSI, however these are the most commonly used. You can read more about the certification process. We'll discuss the benefits of each type of certification and how to choose one for you.
PADI
PADI stands for Professional Association of Diving Instructors. The organization was formed in 1966 by John Cronin and Ralph Erickson. It's a membership-based organization and a diver training organisation. Before they can teach others, members must earn the PADI certification. PADI certifications, which are internationally recognized, are recognized as the standard for teaching diving. These certifications assure the highest standards for safety and training of all scuba divers.

Scuba Diving International
Scuba Diving International (SADI), is an organization that offers certifications and training in scuba diving. Technical Diving International (TDI) is the recreational arm. SADI's goal is to improve scuba skills. There are certifications available for all levels of diving including advanced divers and beginners. Besides scuba certifications, SADI also provides a wealth of information about scuba diving.
SSI
You may be wondering which scuba certification is best for you. The SSI and PADI courses look very similar, but there are some differences in how the skills are taught. PADI requires that all students must complete all skills within a set order. SSI is more flexible and allows a diver the flexibility to skip a skill if it's not working. This will allow them to gain confidence.
Other certification bodies
There are hundreds upon hundreds of agencies that can award scuba diving certificates. Although most of these agencies follow the same basic hierarchy, names and requirements can differ considerably. In general, instructors, open water, and divemaster are the equivalent certification levels. Below is a guideline for scuba diving qualifications. As benchmarks, the ISO 24801-2, ISO 24801-3 and BSAC certifications are used.
Specialties available
There are many certifications in scuba diving. These courses are designed to introduce divers into new worlds under the ocean's bottom. Divers have hundreds of options for specialty courses. There are many specialty courses that allow divers to observe night creatures, such as octopi (and certain types of fish), and night diving. Some of these courses even allow divers to weave baskets while underwater.

Cost of certification scuba diving
There are many factors that affect the cost of certification. PADI Open Water certification is an example. This course can run around $500 but it might be more expensive if your plan is to dive in Maui. The certification price includes all scuba gear, including masks and fins. It is a life-long achievement and a great way for you to get started scuba diving in ocean.
