Regulators and tanks as well as the and the valves attached to the tanks, all form part of your breathing system – or life-support system, if you like. Claude has been a service technician for brands such as Mares, Aqualung, and Apeks for decades, and since 2023, he has also worked with the Hollis Prism2 rebreather. A few years ago, Claude decided to specialise in Apeks regulators exclusively. He has been blending Nitrox and Trimix for a long time, using the traditional method of partial blending.

To ensure the highest safety standards, Claude is very meticulous about keeping his tanks and valves clean, servicing them regularly, and logging all maintenance. Recognising that times change, and that “grandfather’s rights” may no longer hold as much weight, Claude updated his qualifications in 2023.
