Water Entry

When arriving at the dive site, it is always necessary to assess their conditions to ensure that they are appropriate to the experience and limitations of divers. There are basically two types of water inlets: from a vessel or from the coast.


The most used entry in large vessels is the “giant step”, and care should be taken to hold the regulator in the mouth and mask on the face when jumping. In smaller vessels, the entrance of the coasts is mainly used. In any of these situations, it should always be checked that the inlet area is clear, to avoid falling on top of a diver who is already in the water.

After entering the water, still on the surface, the sign “I’m fine” (OK) for the boat should be made.


Before entering the water, the waves should be observed, checking their frequency and where they burst. To enter from land one can use one of two techniques:

  1. After all equipped, except the fins, quickly go through the burst by breathing through the regulator (the wave must be faced with the body aside and grabbing the mask). Once the blasting is overcome, the fins should be put on, inflate the vest, change the regulator for the tube and swim to the place of descent.
  2. After all equipped, including the fins, enter with their backs to the sea, not failing to look at the burst. It has the advantage of already taking the fins paved, but the balance is more difficult and it is necessary more attention and hold all the equipment so that nothing is lost. Recommended for those who have the most experience.


After entering the water, still on the surface, it is important to check buoyancy. You should have water at eye level with lungs full and sink slowly when it expires. This means that the ballast is correct. Before starting the descent, check the adjustment of the vest, the position of the regulator or the 2nd emergency floor, the belt placement and the mask. Once we’ve made sure that all our equipment and the companion’s are properly placed and operational, we’re ready to start the descent by taking air from the vest and lungs.
