Inspiration for Divers OUR MISSION...

To help divers dive better - explore further, stay longer and enjoy the ride along the way. This is not a hollow promise.

We do this by designing and manufacturing innovative (often revolutionary) products that are easy-to-use but enhance diver performance - even in the harshest conditions. Everything we make is conceived, tested and assembled in our factory and research centre in the heart of Cornwall, UK. We aim:

- To be the be the best in everything we do from the boardroom to the shop-floor.
- To help educate, support and inform the worldwide diving community wherever we can. Our doors are always open to divers who wish to visit and we're happy to discuss any aspect of diving - from the operation of rebreather units, to specific dive plans, to advice on DIY servicing and repairs, the supply of custom tools or any other questions you may have. Give us a call to arrange a visit.
- To adopt a no-compromise-on-quality approach to every product we make.
- To enjoy diving with the kit we make. Right now we’re pushing the boundaries of technical and sport diving through advanced product development – producing kit that allows divers to unlock their potential and expand their dive horizons safely, efficiently and in comfort. Our 6th generation Inspiration range of closed circuit rebreathers is a testament to our constant R&D drive-to-improve. Through extensive research and punishing test regimes we aim to make equipment for divers that is built properly, works well and tackles the snag-points and problems we all come across underwater. Where that will lead us next, we’re not always sure. But that’s just part of the adventure.

Training the trainers at Lake Annecy, and what's followed. 🇫🇷🤿

In October 2018, the AURA regional commission of the French Federation (FFESSM) organised its first training of instructors on our AP Diving CCRs. Nine days at Lake Annecy under Jean-Pierre Montseny gave the region six new instructors. We were delighted to see it. 👏

FFESSM's CCR instructor training has continued since. Its most recent national course listed on its site (October 2025) covered our Inspiration, Evo+ and Evolution rebreathers, alongside other manufacturers' units.

Good rebreather diving starts with good training, and we're proud to see so many French instructors teaching on our kit.

And we're coming to Paris. 🗼
We'll be exhibiting at Salon de la Plongée, Paris, 14th-17th January 2027. Come and meet the team, ask us anything about CCR and the Inspiration range, and tell us about the diving you want to do.

🌊💙 Blue Planet III is here!

If there's one thing that reminds us just how incredible our oceans are, it's David Attenborough. 🐋

The new series takes us deeper beneath the waves, revealing extraordinary marine life, fascinating behaviours and a whole new appreciation for just how intelligent, beautiful and precious our underwater world really is.

As divers, we get to experience a little of this amazing world first-hand, but there's always so much more to discover. 🌍🤿

A lovely reminder of why our oceans deserve our love, respect and protection.

Definitely one to add to the watch list!

Lots of fish, a calm reef, and a lost tooth. 🐠😄

A fun dive on Panorama Reef in Safaga, Egypt, from the Red Sea Silence CCR week with Orca Diving. Plenty to see, and as Tino de Rijk says in the description, you'll want to watch to the end for the tooth. 🤿

When you're breathing with very few bubbles, you can take your time and let the reef carry on around you. 🫧

Into Suluin Cave. 🇹🇷🤿

After being closed to diving since 1996, Suluin Cave, at the foothills of the Ta**us Mountains on the Turkish Riviera, has been explored again, and our friends at ATMOS MISSION shared this footage with us.

Over a series of demanding exploration and documentation dives, the team progressed through the cave to its end at 117 metres, using CCR, trimix and experimental breathing gas mixtures. We're proud that AP Diving CCRs were among the units supporting the team throughout. 🙌

Their words say it best: different pieces of equipment, one common requirement. Reliability when there is no room for compromise.

Huge respect to the whole team on a serious piece of exploration. 👏

Know an open circuit diver who needs to try CCR? Tag them. 👇🤿

RE-CYCLE. SCRUB. REFRESH. RE-USE.

On open circuit, most of your gas is bubbled away with every breath, and the waste climbs the deeper you go. On a fully closed circuit rebreather, your exhaled gas stays in the loop. It's filtered, refreshed and recycled back to you to breathe again. Bubbles escape only on ascent and when you clear your mask. 🫧

Elegant gas mixing on the fly. The Inspiration's controller injects oxygen to hold a constant PO2, the setpoint, chosen by the diver. The oxygen fraction in the loop changes with depth, so the unit mixes a suitable nitrox for every depth, oxygen-rich throughout the dive and richer still at decompression depths.

And your oxygen use doesn't climb with depth. It's governed by your metabolism. At an average rate of 1 litre a minute, the Inspiration xpd's 3-litre oxygen cylinder, charged to 200 bar, holds 600 litres: about 10 hours' worth of oxygen from a single fill. A typical Inspiration dive uses around 30 bar per cylinder.
