Deco Diver 47

If the Deep Diver certification is not enough for you, but you want to try the most challenging diving experience, the Deco Diver 40, deco Diver 47 and Deco Mix courses introduce you to decompression diving.

The Course

It is a transition course between recreational no-decompression courses and technical courses where you can extend your time and depth limits.

The main feature of these courses is that although they carry out more demanding dives than recreational ones, they do not require purely technical equipment but can be carried out using normal scuba equipment with specific refinements.

The Deco Diver -47 course is the natural continuation of the Deco Diver 40 course and expands the previous one by extending the depth up to -47 meters.

This course is available only in Italian.

To participate in an ISDA course it is necessary to present a medical certificate of suitability for diving activities. The doctor who signs the certificate cannot be the student himself. The medical certificate is valid for one year from the date of issue.

Furthermore, the student (or a tutor if the student is a minor) must complete the personal medical history form.

The Instructor may, despite all the prerequisites are met, refuse the student the opportunity to participate in the course.
