PADI certifications are a great option for certified divers. PADI offers several levels of training. You will find three main components to most courses: an online self studying module to teach you diving theory, confined diving to improve your equipment's comfort, and open water divers to put all your new 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 various courses for those who wish to become diving professionals. PADI offers many certifications from Open Water Diver to 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 may be completed online or in-person. The training will include several sessions in open and confined waters. An instructor who is specialized in water safety will assist you with organizing your skills according to how you perform.
NAUI
There are many differences among the NAUI Certification charts and PADI. Most notable differences are in certification requirements and teaching methods. These differences can make a big difference in a diver's ability level. The best way to choose which certification to pursue depends on your attitude toward diving and your physical capabilities.
