Poseidon has announced via social media that they are offering an upgrade for MKVI units.
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.
