If the student does not meet these requirements, the course needs to be extended by one (1) day and we will charge an additional 100 euro for this extra day.

Extra note!

1. To get the most out of your Tec 50 training it is important that you have control over your buoyancy and trim. As a guideline, you should be in a nearly horizontal position and remain stationary at a target depth while demonstrating a skill.

If you are unsure whether you can meet these requirements, consider following our XTend on TB – Trim and Buoyancy training.

2. If you want to do the Tec 50 in sidemount configuration than you need to be certified as a PADI Tec sidemount diver and have proof of sufficient experience in sidemount diving. Please discuss with us for clarification. In that case the rental of the sidemount equipment is included in the course price.

3. If you need our pick-up service, please contact us about the possibilities.
