DSAT TecRec courses provide the techniques and procedures necessary for diving beyond recreational dive limits. These are some of the most intensive, yet exhilarating, courses you'll find. Technical diving isn't for everyone but if this type of diving appeals to you and you're willing to accept the risks, responsibilities and obligations, you'll find it one of the most rewarding dive experiences you'll ever have.

Tec 40

Tec 40 is the first rung in the Tec Deep ladder, the first subdivision of the full PADI Tec Deep Diver course consists of the first four dives.You will learn to use decompression software and dive computers to plan and make decompression dives with no more than 10 minutes of total decompression and not deeper than 40 metres/130 feet. By the end you will be qualified to use a single cylinder of decompression gas with up to 50 percent oxygen (EANx50) to add conservatism to the required decompression.

Pre-requisits for the Tec 40

Pre-requisits for the Tec 45

PADI Tec 40 certification (or equivalent) 50 logged dives with the following:
- 12 dives were made with enriched air nitrox deeper than 18 meters - 6 (with or without EANx) dives were deeper than 30 metres

Be a PADI Advanced Open water diver (or equivalent)
Be a PADI Deep Specialty diver (or equivalent)
Be a PADI Enriched Air diver (or equivalent)
Have a minimum of 50 logged dives, of which at least
10 dives must be on enriched air
12 dives must be deeper than 18 metres
6 dives must be deeper than 30 metres
Obtain a dive medical signed by a physician

Tec 45

The Tec 45 course picks up where Tec 40 leaves off and takes your training as a tec diver further and deeper. It is the second sub course in the full PADI Tec Diver course. Building on the Tec 40 program, the Tec 45 module covers the skills, equipment and planning needed to dive to a maximum of 45 metres. The knowledge to plan and execute single and repetitive decompression dives using a single stage cylinder of EANx or oxygen to accelerate or add conservatism to the decompression stops. There would be no time limit to amount of decompression. Prepare for and respond to foreseeable technical diving emergencies. Master the basic skills and procedures you’ll need as you move into deeper technical diving.

Tec 50

Building on the Tec 40 and 45 course foundations, the Tec 50 (formally Tec Deep Course) consists of five Practical Applications, and five Training Dives. Using twin manifolded tanks for the back gas plus two side-mount tanks with up to 100% oxygen for decompression. Tec Deep training takes three days to complete. The course will qualify you to make gas switch, extended no decompression dives, decompression stop dives and accelerated decompression dives using air, Nitrox or up to 100% oxygen to 50m / 165ft, using technical diving equipment and procedures.
Theory is home-study or classroom with workbook with six Knowledge Reviews and Final Exam to complete.
Pre-requisites for the Tec 50

course are:

PADI Advanced Open Water Diver (or qualifying certification from another organization)
PADI Rescue Diver (or qualifying certification from another organization)
PADI Enriched Air Diver (or qualifying certification from another organization)

PADI TEC 45 certification (or equivalent)
Have a minimum of 100 logged dives of which 20 must be enriched air dives, 25 dives must be deeper than 18 metres/60 feet and at least 15 dives must be deeper than 30 metres/100 feet
