I noticed they used very high-quality parts and materials which I’m glad Poseidon did there. Being able to set up your very own emergency air supply helps me when I need it the most, which is when my breathing becomes a problem. It really knows how to take care of that feeling.

It has limited pressure usage at a depth that might limit divers. Not the best fit for you me think. I have gotten about this near 5 stars with what it is like and got more happy about this purchase after being given the use of it.

I’ve been using the Poseidon EBS (EU) for a few dives now, and I must say that it’s been a game-changer. It provides a comfortable breathing experience even at depths. I can not recommend this more!

I wish it came with a protective case for easier storage and transportation. It’s a great device for scuba divers, and I feel confident when using it. The Poseidon EBS (EU) exceeded my expectations in terms of breathability and durability. Would highly recommend!
