Take responsibility for your own safety with a H2Odyssey Extra Air Source.
You're 40 metres (130 ft) down, and your Primary Air Source malfunctions. You can't get air! What do you do? Pull Out your Extra Air Source, Calmly make your way to the surface, make a Safety Stop, and once back on the boat or on shore, thank your Lucky Stars you dived with the H2Odyssey Extra Air Source.
The H2Odyssey EAS removes existing limits on Redundant Air Systems currently on the market and allows you to configure an Emergency Air Source tailored to your diving needs. Combined with the 2.7 litre (19 cubic foot) capacity Catalina S19 Aluminium Cylinder, this system is great for hookah diving, or scuba diving deeper recreational depths (less than 40 metre). The Extra Air Source will get you to the Surface and even provide you with enough air for a Safety Stop if configured correctly for your maximum dive depth.
The H2Odyssey Extra Air Source with Catalina S19 Cylinder is an Essential Safety Item when Solo Diving.
Having a Redundant Air Source for Increased Safety provides you with an Independent Emergency Air not Dependent on your Primary Air Supply. An Octopus or Breathable Inflator System both depend on the Reliability of your Primary Air Source. If it malfunctions you're Out of Air!

Cylinder Colour: Brushed Aluminium or Yellow.
We recommend the Brushed Aluminium. Most of the time the cylinder is in a bag, so the colour isn't seen. Eventually the Yellow paint starts to come off and for a long time you will have flakes of it everywhere.
Adding a small Button SPG to the first stage enables you to know the contents of your cylinder. It also enables you to know when to stop when doing and ait fill transfer from another cylinder.
A standard Low Pressure Regulator Hose can be added so that the 2nd stage can be separated from the 1st stage just like your primary and octopus 2nd stage regulators. Thus this becomes a pony cylinder type setup. We recommend using a 100 cm (40 inch) length hose such as the Miflex Xtreme Regulator Hose 100 cm in Fluro Yellow. We also recomend adding a Sonar LP 90 Degree Swivel Adaptor for Regulator to the hose setup.
Adding a H2Odyssey Extra Air Source FA-2 Station Filler Adaptor enables you to refill your Redundant Air System when you go to the dive shop or on a charter boat. Thus you don't have to sacrifice some of your primary air source supply to refill your EAS cylinder.

Please Note: We do not use or recommend Spare Air products. The H2Odyssey Extra Air Source solutions allow you to match an appropriately sized standard scuba cylinder to give you the right air capacity for the diving you do. Spare Air products provide a choice of 1.7 or 3 cu ft air capacity which we consider to be too little. H2Odyssey products also meet the European EN250 safety standards.
What We Think...
- This is a great safety device for hookah divers, scuba divers and solo divers staying less than 40 metre deep.
- We strongly recommend you buy a 100 cm (40 inch) regulator hose and turn this into a pony cylinder setup.
- We recommend you buy the Filling Station Adaptor so that you can fill the cylinder at a dive shop and thus not have to sacrifice air from your primary cylinder air.
