Regulators are the most important part of your air delivery system: they allow you to breathe underwater by converting high-pressure air from your tank to ambient pressure. Think of it as your underwater life support! Owning a regulator gives you peace of mind because you know how well it has been maintained and how it breathes. When choosing a regulator, you should consider performance, size, what will best fit your level of diving experience, and where you want to go in the future.  Your regulator can last you up to 20 years if you take care of it and choose well to begin with; let us help you make a decision that dive with you for years to come.

Below is the selection of regulators we have available for purchase at our facility. Stop by and our retail specialists will be happy to answer any questions.
