TEC Advanced Wreck

This course builds on the TEC Wreck and allows you to perform dives with deco times of up to 30 minutes.

Training content

In the TEC Advanced Wreck course, decompression dives up to a maximum of 30 minutes decompression time are carried out and overhead dives are only permitted in large and easily accessible wreck areas. Some exercises are carried out without visibility, with a blind mask, while other typical skills are practiced under time pressure. To ensure your safety, you must be able to reach the open water very quickly if you feel uncomfortable. Overhead diving in closed rooms without direct access to the open water is prohibited.

If you have completed the TEC Fundamental or higher, you have the option of combining the TEC Wreck and the TEC Advanced Wreck course.
