Why dive Poseidon?

Poseidon products have done their job on North Sea oil rigs, they have done their job in complex Arctic Search and Rescue missions. They will do their job and disappear into your peace of mind. Poseidon's Fully Automatic Rebreather - the Poseidon Se7en is a breakthrough within the recreational diving community. It may be the longest and quietest dive you will ever experience. The recently introduced M28 Dive Computer represents a unique "next-generation" technical dive computer.
