Today we celebrate the 100th birthday of Sir David Attenborough.

For many of us, the fascination with the underwater world started long before our first dive. Watching the unseen world brought to life through his storytelling made us all ask the same question… what else is out there?

That curiosity is what gets us diving. It pushes us to explore further, learn more, and gain a deeper respect for the oceans we’re privileged to experience.

From everyone at O'Three, Happy 100th Birthday Sir David, and thank you for inspiring so many people.

Having recently been involved in a historic artefact removal project on the HMHS Britannic it's safe to say we’re proud to have Indepth Technical Diving - Barry McGill back in the fold as our latest O’Three Ambassador and support his continued exploration and preservation of some of the world’s most iconic shipwrecks.

His experience, dedication, and passion for underwater heritage perfectly reflect what O’Three stands for.

's latest video is a perfect example of how a simple question can be expanded into a more complex decision.

We’re often asked “Which suit is best?” and our answer is always the same “What kind of diving are you doing?”.

Depth, duration, conditions, and personal preferences all play a role in choosing the right drysuit, and getting that decision right makes all the difference.

Make sure to check the comments below for the link and see how Dom approaches this process for his latest dive on the Britannic.

We’re saddened to hear of the passing of wildlife cameraman Doug Allan, whose work brought the natural world closer to all of us.

His imagery defined a generation of storytelling.

A life spent exploring, documenting, and inspiring... A true pioneer.

Rest in peace.
