In diving we can see these different styles, there is people that just want to do a nice tour and see a beautiful view, they are not interested in transforming their hobby in a sport that requires a lot of training.
We also have divers that see diving as a sport, in the same way as who climbs a hill these divers wants that their equipment function in the most optimal way as possible, that their movements be fluent and be able to move underwater in a harmonic and efficient way. Divers that practice diving as a sport discipline seek for the exploration of new places and many times its not enough following a guide that will always lead them to the known places. When diving becomes a sport the physical condition becomes important, mental training is also a key point, the technique to move the body and the correct use of the equipment is fundamental. Every detail related with diving becomes relevant and the training becomes imperative.
As other sports, divers can specialize in different styles of diving that require specific training and in some cases the risks associated with the activity will increase together with the complexity of the activity.
A diver that wants to transform this activity in a sport will get attracted to use specific equipment and to possess its own equipment with which it can familiarize at full, on the other hand a diver that only wants to go out for a tour once in a while only wants to be able to use the type of equipment that will rent in the common places that will visit.
