What is Extended Range Diving?

What is Extended Range Diving?

Do you have dive experience beyond open water, and a few hundred dives to show for it? Congrats! You have reached an enviable level of knowledge and proficiency that is necessary for exploring the underwater world further. Now, if you are looking for something more than just diving within no-decompression limits down to 40 meters but not quite ready yet to take on technical diving - boosted recreational diving could be exactly what you need. This type of scuba experience has different names depending on your preferred diving organisation (BSAC, PADI, TDI or SSI), but widely known as Extended Range Diving - it focuses mainly on boosting your skillset above regular open water levels to maximize the enjoyment and exploration of diverse dive sites up close.


Reason to move into extended-range diving:

  • Stay underwater longer and explore deeper your favourite dive sites
  • Expand knowledge in the physiology of diving
  • Learn how to plan and execute decompression dives
  • Learn how to use additional scuba equipment beyond just one tank 
  • Learn to use nitrox up to 80-100% for decompression

If you’re a scuba diver looking to take your passion further, then extended-range diving is the best way to do it. It’s a more advanced form of recreational diving and entails learning new techniques, using different gas blends and even entering into decompression territory – something usually only experienced by technical divers. Extended-range diving training differs from one dive agency to another so it is essential that you choose carefully before jumping in. And don't worry — on any course worth its salt, you'll get lots of support and advice as well as plenty of training for how to plan dives with higher oxygen mixes or when introducing helium into the equation. So let's take a closer look at what extended-range diving holds in store!
