To obtain the first PADI “Open Water” certification, it is necessary to do the theoretical classes, 4 dives at sea and the confined water classes. Normally, confined water classes are held in a pool. However, it is also possible to make them at sea, as long as its name says, the space is confined, without current and shallow.
We believe that doing confined diving classes is not recommended at sea, since visibility is not always good. Also, no matter how much the sea is calm, there is always some current. In the psychological aspect, the sea can create more anxiety in a student who has no aquatic experience.
On the other hand, the classes in swimming pools are perfect to start diving and become familiar with the water. The main advantages of making the classes confined in the pool are:
- Pleasant temperature: You can have a heated pool or that is at a pleasant temperature. On the other hand, the sea in Lima is always below 18 degrees Celsius.
- Controlled depth: With nervous students you can start with a depth of just 1.2 meters, in which with just standing you are with your head out of the water. Then you can gradually gain more depth.
- Excellent clarity: If the pool is properly maintained, the clarity is unmatched. Even more so when compared to the sea in Lima, which does not enjoy the best clarity.
- There are no currents: Without currents you can learn and practice much more easily all the techniques, which will then be used at sea.
