PADI requirements for all grades and ages

PADI stands for International Association of Professional Diving Instructors. It was founded by Ralph Eriksson and John Cronin at 1966. Based on the principle of teaching, they designed a complete teaching system, which quickly made diving activities flourish. At present, PADI is headquartered in Santa Ana, California, and has offices in Canada, Japan, Australia, New Zealand, Britain, Switzerland, Norway, Sweden and Singapore. PADI China is managed by PADI Asia Pacific Company in Sydney. PADI has 25,000 coaches around the world and issues more than 500,000 diving licenses every year, which makes PADI the largest diving training institution in the world. Generally speaking, PADI, like other diving organizations, is a profit-making commercial organization, which is managed by CMAS (World Diving Conference). PADI trains its own diving instructors and instructor visa officers around the world, and certifies the diving shops and clubs where these instructors are located. Certified diving shops and clubs will be authorized by PADI to become PADI diving centers. According to PADI's teaching standards and standard courseware, students are trained and assessed, and PADI diver grade certificates are awarded. Diving shops or clubs certified by PADI Diving Center are generally considered to have a considerable number of diving equipment, suitable training places and can provide training courses that meet PADI standards. At the same time, the diving center also has the conditions to sell and maintain diving equipment, which can provide more professional services for students. PADI's training courses are not only constantly improved to meet the needs of divers, but also take into account the revision and update of diving activities in its training courses. In addition, the long-term plan of marine environmental protection initiated by PADI not only teaches divers to attach importance to environmental protection, but also trains divers to become responsible divers. All PADI training courses have the same strict standards all over the world, which is also the biggest advantage of PADI training system. Divers learn the same skills and theories no matter where they train, the only difference is the learning environment. In 2007, PADI established an E-Learning online training system, so that those who are interested in learning diving can learn the diving theory officially formulated by PADI online anytime and anywhere. Then, practice the skills of calm water and open water in authorized diving centers all over the country. PADI commonly used diver level: open water diver (traditionally known as OW), which is the most basic diving course.

Participants must have the qualification of junior diver in open water or other equivalent level. First Aid First Action Medical First Aid Training is an independent course of first aid and cardiopulmonary resuscitation. This course is mainly medical training, and there is no diving course, so participants do not need to have any diving qualification. The duration of the course is about 8 hours. In the PADI system, if students have passed the training of cardiopulmonary resuscitation (CPR) of the International Red Cross, they may not study EFR. The rescue diver rescue diver course is the first time that a diver has been asked to concentrate on another diver while learning to dive. In this course, students will learn how to avoid dangers and accidents and be able to cope with emergencies in the water at any time. This course consists of 12 rescue exercises at five subject levels. Participants must have senior divers in open waters or other qualifications at the same level. Professional diving course is a short-term professional course, and the course arrangement is usually 1 ~ 2 days, mainly 2 ~ 4 professional diving trainings. The qualifications of participating students vary according to the difficulty of diving. Shi Ming Diver When a diver has completed five professional diving courses of PADI and obtained the qualification of rescue diver, he can apply for a Shi Ming diver's license. Shi Ming diver is the highest honor for leisure divers. Diving master is the first stop for diving teaching and training. Divers with a master's license in diving can be engaged in diving guides or assist in diving teaching and training. The long diving course includes three main contents: diving theory and knowledge, diving skills and practical marine experience.

Padi (pppoe Active Discovery Initiative) is the first stage of pppoe protocol discovery, which is sent by the client to the pppoe access concentrator of the ISP. In the Ethernet frame structure of PPPoE, the value of the encoding field is 0x09, and the value of the session ID field is set to 0x0000. In this step, the Ethernet destination address is broadcast, and the data packet must contain the exact service name. Complete the discovery phase with PADO(O for quotation), PADR(R for request) and PADS(S for session confirmation).
