Poseidon Diving Systems recalls Poseidon M28A dive computers

Poseidon M28A dive computers are subject to this recall. They continuously calculate and provide the data that divers require. The Poseidon SE7EN Rebreather with the M28A can be used separately or together. This recall only applies to dive computers with serial numbers that begin with "M28A-". On the rear of the recalled dive computers are the serial number and two metallic wet-switches.

Poseidon Reef App Launch


Plan your next diving adventure in the simple to use, easy to navigate interactive planner. Diving an open circuit or rebreather? Doesn't matter. The app has different dive modes and deco models available to match your setup and preferences regardless of level.

Choose between single dives or a series of dives and let the app calculate needed technical stops. Easily tune the gradient factors to see the difference in dive time and get a summary of the result as well as a detailed list of run time and gas switches if applicable.

Poseidon Announces Upgrade Option For MKVI Rebreathers

The (34,000 Swedish Krona) package consists of a SE7EN E-module, two HP-sensors and a HUD.

The deadline for this upgrade is 24th December 2017 and it cannot be combined with any other offers. The old MKVI e-module must be returned to Poseidon and the owner will also need to either buy a M28 or a Paddle with a can connector.

Poseidon has also confirmed that there will be a minor upgrade for current SE7EN owners so that their rebreathers are solid state sensor ready.

Taking the SE7EN for a spin

The nascence of recreational rebreathers was just waiting to happen. Spurred on by rapid advances in technical diving, new materials and technology, coupled with cost reductions, the allure of long and quiet dives, with vastly improved non-deco times, had to seep from the technical communities to recreational diving, leading to the design of a new generation of closed circuit rebreathers aimed primarily at recreational divers.
