At the Beginning you learned as a diver that you carry your tank on your back because that was the standard.

SideMount configurations have evolved from Cave and penetration diving.

SideMount has established its place for all types of diving.

With the SideMount configuration there is no heavy weight on your back anymore.


  • carry more gas for both recreational or a technical dive.

  • dive longer, safer and easier. 

  • Take advantage of your No Decompression Limit when using Nitrox on recreational dives.

  • Setup tanks on land and attach inwater

  • Keeps the weight of the tanks off your body until you are ready to start the dive.

With TwinSet diving you can carry more gas so whether you are making a recreational dive or a technical dive, It means you can dive longer, safer and easier. Carrying an extra tank allows you to take advantage of your No Decompression Limit when using Nitrox on recreational dives.

Using a TwinSet with a manifold simplifies the use of two tanks, as you are able to breath from the primary second stage regulator as both tanks breath down at the same time. Unlike SideMount where you switch between tanks.  

The use of a TwinSet configuration for Tec dives cuts out the need to switch second stage regulators until required for using any Deco mix's.

PADI Tec 40, 45 and 50

Tec 40 Diver

The PADI Tec 40 course is where you transition from recreational scuba diving to technical diving.

It’s a great beginning on your Tec path because you will be qualified to make limited decompression dives to 40 metres.

To enroll in the Tec 40 course, you must be:

  • A PADI Advanced Open Water Diver

  • A PADI Enriched Air Diver with at least 10 dives using enriched air deeper than 18 metres/60 feet

  • A PADI Deep Diver.

  •  At least 18 years old

  • Have a minimum of 30 logged dives

Tec 45 Diver

The PADI Tec 45 course is the next level on your Tec path.

You’ll extend your depth limit to 45 meter's. You’ll learn to plan and execute repetitive decompression dives. You will learn how to use a single stage decompression cylinder with either backmount or sidemount.

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 deeper than 18 metres.

  • 10 dives deeper than 30 metres

  • At least 18 years old

Tec 50 Diver

The Tec 50 course allows you to dive to a maximum of 50 meters. You will know how to make extended decompression stops using up to two gases.

To enroll in the Tec 50 course, you must:

  • Be a PADI Tec 45 Diver

  • Have a minimum of 100 logged dives, with at least 20 dives on enriched air deeper than 18 metres

  • 15 dives deeper than 30 metres

  • At least 18 years old

TDI Advanced Nitrox and Decompression Procedures

What will I Learn?

On this course you will complete the TDI Advanced Nitrox and Decompression Procedures theory with your instructor.

This will include content on oxygen exposure tracking for technical and accelerated gas switch dives, equipment set up and configuration, physiology and decompression as well as a gas switch decompression dive planning workshop.


You will then move to our pool or a suitable confined water site.  Here you will learn the skills required to safely conduct decompression, gas switch dives. You can use a TwinSet and stage cylinder or SideMount and stage cylinder configuration.  This session also gives you the perfect opportunity to put the equipment changes made in the workshop to the test.


We will then progress to the 6 open water dives, during which you will demonstrate your ability to safely conduct at least four decompression dives to a maximum depth of 45 meters.

The final dive will include a switch to a rich nitrox mix to accelerate your required decompression.
