PADI Tec Basics

from €343

Course Description

The PADI Tec Basics course is designed as a ‘bridge’ between recreational and technical diving. Within this course you’ll get to learn about, and use, technical diving equipment along with associated procedures and skills, and begin to explore methods of gas planning. The course is run within recreational limits (decompression diving is NOT part of this course), and as it uses segments from the PADI TEC 40 course you can continue on and achieve the full TEC 40 rating without having to repeat these segments again.

The PADI Tec Basics course is not only for those wishing to continue on to technical diving, as it also has many advantages and benefits for recreational diving as well. Having a larger gas volume, and built-in redundancy for a separate breathing gas supply, it makes an ideal course for those who regularly dive deeper. And for those who may want to consider diving solo this course provides a solid foundation from which to enrol onto the PADI Self-Reliant Diver specialty

The PADI Tec Basics course requires four dives and two practical classroom sessions over three days, and combined with the PADI Tec Basics Information pack, provides you with the knowledge and skills to start you on your journey of twinset diving.

Course Content

The PADI Tec Basics course includes everything you´ll need. We´ll supply you with –

• Full equipment for technical diving including wetsuit, twin bladder wing, harness and back plate, dual regulator set, air/EANx dive computer, twin set cylinders, decompression cylinder, hood, gloves, boots, fins, mask and weight system
• Primary dive torch, cutting tool, DSMB & reel, wetnotes, and compass.
• PADI Tec Basics Information pack
• Certification upon successful completion

And remember that on this course there will never be more than three students per course!

You can book this course from €343 or alternatively enjoy a fully inclusive diving holiday from just €445 (2 people sharing)

Tec Basics Course

The PADI Tec Basics course comes with an informative and easy to understand information pack. Within this pack you´ll get to look at -

Tec Basics Course• The limitations of the PADI Tec Basics course
• An introduction to the PADI Tec40 course, and how this fits in to the overall PADI Tec course structure
• Equipment used for Technical diving; Exposure suits, cylinders, wing, regulator sets, stage/deco cylinders, DSMB’s, etc.
• Calculating best oxygen blend for our bottom gas
• Introduction to switching to a higher oxygen EANx
• How to use desktop decompression software
• Turn pressure and turn time

Included within the manual are two Knowledge Development sections that you´ll need to complete, and are designed to help you better understand and retain the information.

With the knowledge development completed it´s time to start on our practical and in-water sessions.

Day One

Tec Basics CourseOn our first day will be split into two segments; knowledge development & introduction to technical diving equipment, and a confined water (swimming pool) skills session.

So first we’re going to introduce you to your ‘Technical Diving Rig’. We’ll identify all of the key components of this, make sure you have an understanding of their use, and how to assemble it. You’ll be given plenty of time to practice assembly, along with a ‘dry’ practice of some of the key skills for the confined water session.

For our confined water session, we’re going to run through some of those important skills for your Tec Basics course, in particular-

Working in a team, assemble and inspect the basic technical diving rig following the previously described rigging philosophy and to meet individual/environmental needs
• Demonstrate the proper weight required for the dive
• Demonstrate neutral buoyancy while wearing the basic technical dive rig underwater in water too deep in which to stand by hovering for 1 minute without sculling or kicking
• Within 30 seconds, independently close the cylinder valve to a regulator that is experiencing a simulated free flow
• Assist a team mate by closing the correct valve to a regulator that is experiencing a simulated free flow
• Within 30 seconds, independently close the isolator valve in response to a simulated manifold leak
• Respond to a simulated out of gas emergency by signalling a team mate, switching to the teammates long hose second stage, then swimming 30 metres/100 feet using the long hose regulator and maintaining contact with the team mate
• Respond to a teammate’s simulated out of gas emergency by, on signal, providing the teammate with the long hose second stage, switching to the short hose secondary, then swimming 30 metres feet as the teammate uses the long hose regulator, maintaining contact

Day Two

Tec Basics CourseThe day will start by completing the last section of Knowledge development, and then we’ll devote time to look at gas planning and the use of desktop software. We’ll return again to the swimming pool to complete our remaining skills.

For our confined water session, we’re going to run through the remaining skills for your Tec Basics course, in particular –

• Working in a team, plan the dive following the A Good Diver’s Main Objective Is To Live procedure, and perform predive checks following the Being Wary Reduces All Failures procedure
• Working in a team, perform a bubble check, descent check and S‐drill
• Independently don, remove and re‐don a stage/deco cylinder on the bottom
• Perform gas switches to stage/deco cylinders correctly following the NO TOX procedure
• Shut down both manifold valves and the isolator valve, and switch second stages to maintain a breathing supply, beginning with any valve chosen by the instructor, within 60 seconds
• Deploy a lift bag or DSMB from the bottom in water too deep in which to stand
• Swim at a steady pace at a constant depth for sufficient time to determine the SAC rate
• Using only neutral buoyancy, maintain a simulated decompression stop for eight minutes
• Remove and replace stage/deco cylinder at the surface in water too deep in which to stand.

Day Three

Tec Basics CourseWe’re off to the open sea, to complete two dives, where we’ll be able to explore and enjoy some great diving on the Costa del Sol. Each dive will be a repeat of the confined water dives; during the dive you’ll demonstrate mastery of each skill at different points throughout the dive.

We’ll also use this deeper water to confirm your working SAC rate, and have a chance to see how well our dive planning actually corresponds to our dive.

All of the dives will be ‘No Decompression’ dives (max depth 30 metres), so we’ll be staying within the limits of our planning/dive computers, and/or back gas limits.

If you have a qualification in Enriched Air Nitrox then it is possible to utilise this and extend the bottom times, but only as long as all team members are suitably qualified.


What other courses can you link in, and achieve greater enjoyment and safety under the water? You might be completing this course to decide whether to continue on with further training to PADI’s first level of technical diver training, the PADI TEC 40 course. The benefit of progressing on is that all of the training you have completed counts toward this course, so why not look to complete the PADI TEC 40 course with us, or at any of the PADI TecRec centres throughout the world.

If you’re not looking to continue on to Technical diving, then you’ll find that during normal recreational diving the increased volume of gas you carry often means that your ‘no stop limits’, rather than gas pressure, limits your bottom time. Completing the PADI Enriched Air Nitrox Diver specialty allows you to extend your bottom times by increasing the amount of oxygen in your back gas, and can allow you to use up to 40% oxygen.
