If you want to become a certified diver, you may want to consider a PADI certification. There are many levels of PADI training available. The courses typically include three main components: an online self-study module to get you up to speed on diving theory, confined water diving to increase comfort with your equipment, and open water dives to put all of your newfound knowledge into practice. PADI certifications will give you a solid foundation in diving.
PADI
The PADI certification chart lists different levels of certification. PADI offers several courses for divers who want to be certified as a diving professional. PADI has the right certification for you, whether you are an Open Water Diver or a Scuba Diver.

SSI
The first step to becoming a SSI instructor is to learn the SSI certification chart. Important to note is that SSI certifications begin at the basic level, and go up to more complex levels. SSI certification courses can be taken online or in person. During your training, you will experience several sessions in both open- and confined water. A specialized instructor will help you organize your skills to suit your performance.
NAUI
There are many differences in the NAUI and PADI certifications. The biggest differences are in the teaching method and certification requirements. These differences can have an impact on a diver’s ability to dive. Your attitude towards diving and physical abilities will determine which certification you should pursue.
CMAS
CMAS padi certifications are slightly different to PADI's. While the certifications of both agencies are similar, they are not identical. CMAS requires that you dive to 18 metres and complete 4 training dives. PADI requires five.
BSAC
A diver can complete the BSAC Open-Water Diver programme and then continue with BSAC. The BSAC certification list lists the courses that will help the diver reach the advanced level. These courses can be expensive and cost between 25 and 55 US dollars.

Digital Underwater Photographer
The PADI certification certificate chart for digital underwater photographers provides an introduction into underwater photography and a variety of digital camera techniques. This specialty is available as either a single or two-part course. It covers topics such as colour filters and white-balancing as well as camera setup. Students also learn how to resolve image resolution and file formats.
