What is Tec Diving?

Technical scuba diving is defined as diving other than conventional commercial or research diving that takes divers beyond recreational scuba diving limits. It is further defined as and includes one or more of the following:

  • diving beyond 40 metres/130 feet deep
  • required stage decompression
  • diving in an overhead environment beyond 40 linear metres/130 linear feet of the surface
  • accelerated decompression and or the use of variable gas mixtures during the dive

Because in technical diving the surface is effectively inaccessible in an emergency, tec divers use extensive training and technology to manage the added risks. Even with these, however, tec diving admittedly has more risk, potential hazard and shorter critical error chains than recreational scuba diving.

Why would I want to be a tec diver?

Tec diving not only has more risk, but it requires significantly more effort, discipline and equipment. It’s not for everyone, and you can be an accomplished, avid top-notch diver your entire life without making a tec dive.

However, there are divers who want to visit places underwater that relatively few people can. Many spectacular, untouched wrecks lie at depths well below 40 metres/130 feet. Deep reefs have organisms you don’t find in the shallows. Some people enjoy the challenge and focus tec diving requires. Others want to be involved with cutting edge technologies.

The fun part of  PADI Tec is rising to the challenges as you dive deeper and longer than most divers ever do.


The PADI Tec programme debuted in 2000. Although it is not the first tec diving programme (cave diver training has been around for decades), it is highly regarded.

  • PADI Tec courses are integrated into an instructionally valid course flow that takes you from beginning tec diver to one qualified to the outer reaches of sport diving using different gas mixes.
  • Each level introduces you to new gear, planning and procedures appropriate to extend your diving limits.
  • The PADI Tec course is an integrated sequence of three subcourses: Tec 40, Tec 45 and Tec 50.  You can complete them continuously, or you can complete each level separately with a time span between them.  This gives you learning efficiency, instructional integrity and schedule flexibility.

The Scuba Gear You’ll Use

Tec diving uses much more equipment than recreational diving. The technical scuba gear typically uses two to four or five regulators, a dive computer, and some accessories.


PADI Tec prerequisites vary from course to course, but in order to enrol in Tec 40, which is the normal starting point, you must be:

PADI Advanced Open Water Diver (or equivalent)
PADI Enriched Air Diver (or equivalent)
PADI Deep Diver (or equivalent)
Have a minimum of 50 logged dives, of which at least 10 must be enriched air dives, 12 must be deeper than 18 metres/60 feet and at least six must be deeper than 30 metres/100 feet
Minimum age: 18 years old, and finally, you must submit a “fit to dive” medical signed by a physician.
