Knowledge Sharing

In this section everyone can participate, individually or as entity responsible (schools, centers, agencies, etc.), sharing the knowledge they have acquired over the years related to diving, leaving a personal imprint on each shared knowledge.

To this end we select a series of topics on which the interested entities (we would like to have the participation of all) can participate by sending us their texts to info@skaphandrus.com

Other subjects on which you have already written or published, may also be proposed, because the important thing is to put the information and learning available to all who want to learn.
