PADI TecRec Twinset DivingDepending on your interest level in technical diving, the PADI TecRec program challenges you with five diver level courses: Tec 40, Tec 45, Tec 50, Tec Trimix and Tec Trimix 65. You’ll experience the more demanding and challenging nature of technical diving through an existing state-of-the-art instructional design with PADI quality material and proprietary programs. You train for real-world tec diving, using a balanced mix of independent study, classroom discussion, and surface pool and open water training.

PADI TecRec courses give you the techniques and procedures required for diving beyond the recreational limits. But remember: technical diving isn’t for everyone. If you embrace adrenaline-pumping challenges and are willing to accept the risks, responsibilities ad obligations, you’ll find TecRec to be one of the most rewarding experiences you will ever have in diving.
