TDI Decompression Procedures Diver

This course examines the theory, methods and procedures of planned stage decompression diving. This program is designed as a stand-alone course or it may be taught in conjunction with such TDI courses as Advanced Nitrox, Advanced Wreck, or Extended Range.

The objective of this course is to train divers how to plan and conduct a standard staged decompression dive not exceeding a maximum depth of 45 msw unless taught in conjunction with the Extended Range Course. The most common equipment requirements, gear set-up, and decompression techniques are presented. Students are permitted to utilize Enriched Air nitrox mixes or oxygen for decompression provided the gas mix is within their current certification level.

Who this course is for:

The certified Advanced Diver looking to expand their knowledge of decompression theory and diving techniques

The certified Advanced Diver who is interested in extending their bottom time

The certified Advanced Diver who has interest in moving forward with technical diving education

Course prerequisites:

Minimum age 18

Minimum certification of SDI Advanced Adventure Diver, Advanced Diver, or equivalent

Proof of 25 logged open water dives

What’s in it for you?

Ability to conduct decompression diving activities without direct supervision provided:

The diving activities approximate those of training

The areas of activities approximate those of training

Environmental conditions approximate those of training

Ability to enroll in TDI Advanced Nitrox, TDI Extended Range, TDI Advanced Wreck, TDI Trimix courses

Tec 45

The PADI Tec 45 course is the second part of the full PADI Tec Deep Diver program. You’ll extend your depth limit to 45 metres and learn to plan and execute repetitive decompression dives using a single stage/decompression cylinder. It puts you in a complete tec diving rig, which can be either backmount or sidemount. You’ll also make accelerated decompression dives using EANx or pure oxygen. This is a course where you’ll rise to the challenge and make the commitment to become a technical diver.

To enroll in the Tec 45 course, you must:

Be a PADI Tec 40 diver

Be a PADI Rescue Diver

Have a minimum of 50 logged dives, with at least 12 dives on enriched air nitrox deeper than 18 metres and 6 dives deeper than 30 metres

Be at least 18 years old

Have a Medical Statement signed by a physician within the last 12 months

Academic

Your Tec 45 training consists of three knowledge development sections, three practical application sessions and four open water dives. Building on what you learned in the Tec 40 course, you focus on the function and maintenance of tec diving equipment and associated issues. You continue fine-tuning gas planning and calculating accelerated decompression stops. Plus, you learn to think like a technical diver.
