You must first complete a training program and then receive a certification from a certifying organization to become a certified diver. Scuba diving certification is given by PADI, Scuba Diving International, or SSI. There are other certifying bodies as well, such as SSI, but these are the most common. You can read more about the certification process. We'll explain the differences between each type of certification, and help you choose the one that suits your needs.
PADI
PADI stands for Professional Association of Diving Instructors. John Cronin & Ralph Erickson formed the organization in 1996. It's a membership-based organization and a diver training organisation. Members are required to earn the PADI certification before they can instruct others. PADI certifications have been internationally recognized and are the standard in diving instruction. These certifications are the most rigorous in safety and training.

Scuba Diving International
Scuba Diving International offers certifications as well as training. Technical Diving International (TDI) is the recreational arm. The goal of SADI is to help people develop their scuba skills. There are certifications available for all levels of diving including advanced divers and beginners. SADI offers a wealth information on scuba diving, in addition to certifications.
SSI
If you are looking for a new certification for scuba diving, you might be asking yourself which option is the best. PADI and SSI courses can be compared in many ways. However, there is a difference in the order 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 can help them gain self-confidence.
Other certifying bodies
There are many agencies that offer scuba diving certifications. While many of these agencies adhere to the same basic hierarchy and requirements, some names and requirements might be different. In general, instructors, open water, and divemaster are the equivalent certification levels. The table below gives an indication of the requirements for scuba divers. As benchmarks, the ISO 24801-2, ISO 24801-3 and BSAC certifications are used.
Specialties
There are many certifications in scuba diving. These specialized courses introduce divers to new worlds beneath the ocean's surface. Divers can choose from hundreds of different specialty courses. These include night diving where divers can see nocturnal creatures like octopi, and certain types fish. Some courses allow divers the ability to weave baskets underwater.

Cost of certification for scuba diving
The cost of certification to dive in the ocean varies depending on which class you take, where you are located, and what program it is. For example, the PADI Open Water certification course costs about $500. However, it may cost more if you are going to Maui. The certification costs include the cost of your scuba gear (including a mask, fins, and snorkel). It is a life-long achievement and a great way for you to get started scuba diving in ocean.
