Your diving journey always starts with your diver certification. Diving is an immensely fun activity but needs to be done correctly as it can be very dangerous when done irresponsibly. Finding the right training for the diving activity that you intend to partake can be a challenging task.
There are a number of Diver certification bodies with hundreds of different courses offered; these courses are interrelated through a system of prerequisites and requirements such as age, experience and other factors. Through manual research we have compiled a unified database of all certifications & qualifications offered by the major bodies with notes, prerequisites and age requirements for each one.
The database below should provide some insight to the path that a diver can take in attaining the perfect mix of training necessary for the conditions and activities that he/she desires to partake in.
