PADI Tec 40 Diver

Horizon Divers – Dive Courses
Course Description

The first step to going beyond the recreational diving limits. TEC 40 divers learn the basics of decompression diving and accelerate their decompression with higher mixes of Oxygen. Upon completion divers are trained to a maximum depth of 40m (130’), using two gas mixes up to 50% Oxygen, with a max decompression of 10 minutes. Divers can opt to take this course using a single tank, but doubles are recommended and encouraged.

Additional Information

PADI Tec 40 Diver

The Tec 40 course introduces divers to limited decompression, using software or computers, for diving within recreational depth limits. The course is prerequisite to the Tec 45 and 50 level.

Includes: Certification fees and Tec Deep Diver materials, double tanks (if used) and deco tanks, all air and enriched air fills and local boat trips.

If the diver doesn’t have their own personal gear (fins, mask, wetsuit, back plate, harness, appropriate BCD, regulators, etc) normal equipment rental charges apply.

The diver will learn how to make limited decompression dives to 40m/130ft using a single stage cylinder of decompression gas. Double tanks (or side mounted) are encouraged but not required on this course, although the full standardized technical diving rig will be discussed.

Decompression is limited to a maximum of ten minutes on this course with a single decompression gas up to 50% oxygen being used to add conservatism only.

Skills are introduced and developed to allow handling of reasonably foreseeable emergencies that may occur in this type of diving.

The course consists of one confined water dive, three training dives, three knowledge development sessions and three practical applications.


• Minimum Age: 18 years
• PADI Advanced Open Water Diver or equivalent
• PADI Enriched Air Diver or equivalent
• PADI Deep Diver or at least ten logged dives to 30m/100ft
• A minimum of 30 logged dives, of which at least 10 dives were made with enriched air nitrox, deeper than 18 meters.


To be certified as a Tec 40 Diver, the student must successfully meet all the performance requirements for the Knowledge Development and Practical Application sessions and the four dives involved.
