Oxygen sensors, or "cells," which are used in rebreathers have a limited shelf life and need to be replaced every 12 to 18 months. However, new ones are currently not available to the dive community.
In the United Kingdom, oxygen cell manufacturers have been mandated by the UK government to supply cells to the medical industry, leaving the dive community with back orders.
I completed a Module 1 course on the Inspiration Classic back in the late ‘90s but found that my limited ability meant that maintaining situational awareness while also having to continually monitor handsets was very difficult. In the early 2000s, I also did a series of technical diving courses with Global Underwater Explorers (GUE), and I still rate these lessons as the most significant dive training that I have ever undertaken.
Michael Menduno details the highlights of the various presentations given during the sixth biannual international Rebreather Meeting, which took place 1-5 May 2019 on Ponza Island in Italy.

Diving at a location where only few have gone before is every diver’s dream. Viroit Cave in southern Albania is such a place.
Award-winning underwater cinematographer and documentary producer Nathalie Lasselin reflects upon her dive expeditions in the Arctic and her epic project to raise awareness about the state of fresh water in the St Lawrence River, closer to home in Montreal.
“Rebreather Friendly” dive centres—what exactly does this mean? With emerging technologies becoming more mainstream in the diving world these days, more and more people are making the investment in rebreathers. Everyone knows the advantages of these pieces of kit—extended dive time capabilities, reduced gas usage, quieter and less obtrusive to the aquatic world, etc. But are dive operators thinking on the same lines?
There are many advantages to diving closed circuit for the underwater image creator such as better interaction with wildlife or longer dives. However, there are also a number of disadvantages to consider such as added complexity and task loading.
This information is needed because a number of divers use Spherasorb in their APD units.
APD recommend that divers should use Sofnolime 797 in their unit - the APD rebreathers are designed and tested using this sorb. However there are times when divers will use an alternative sorb due to cost, availability and / or because of perceived advantages in work of breathing or endurance.
"Due to changes in certification standards and changes in approvals of key electronics components that in turn have led to delays in the CE certification process, the expected delivery time for the first batch of M28 Computers will now be in August.
We sincerely apologize for this delay, however it is out of our hands and we are doing everything we can to keep things moving forward swiftly."
