PADI Tec 45

Advance Your Tec Skills to 145' & Use Oxygen as Your Decompression Gas

PADI Tec Course Breakdown:

The PADI Tec Rec Courses are structured to build upon the skills of the previous class. The progression of classes are:


This allows the diver to take baby steps throughout their Open Circuit Technical Diving Courses. There is no bigger concern than task loading a diver with too many skills and variables to early on throughout their course. The PADI Tec Courses will ensure the diver is 100% comfortable with each step along the way of becoming a proficient technical diver.

Tec 45 Objective:

  • To qualify the diver to make limited decompression dives using air, nitrox, and oxygen to a depth of 145' or less.

  • To train the diver in the knowledge, procedures, and motor skills required for decompression diving within the limitations of the Tec 45 certification.

  • To assure the diver understands and acknowledges the hazards and risks associated with this level of tec diving and tec diving in general.

  • To train the diver to prepare for and respond to reasonably foreseeable emergencies that may occur within Tec 45 limits.

  • To lay the foundation to continue your training into Tec 50, Tec Trimix 65, and beyond.

Tec 45 Diver is Qualified to:

  • Make limited decompression dives using air, nitrox, and oxygen to a depth of 145' or less.

  • Use a single decompression gas up to 100% oxygen to make your decompression more conservative or to accelerate your decompression.
