Halcyon H-50D First Stage Regulator

A first stage, two second stages — your primary and your octopus — a low pressure inflator hose and a gauge. You can mix and match all of it depending on how you dive. Talk to us and we will put a set together with you rather than selling you a box.

For most divers, yes. A good regulator, serviced on schedule, should last you a lifetime of diving — it will outlast almost everything else in your kit. That is exactly why it is worth buying properly the first time rather than buying twice.

Balanced, if it is in budget — we would always suggest it. A balanced regulator delivers the same breathing effort regardless of how much gas is left in the cylinder or how deep you are. An unbalanced one gets progressively harder to breathe as the tank empties and as you go deeper, and in cold Sydney water at the end of a dive that difference is noticeable.

Put the money into a good balanced first stage and primary second stage, and go simpler on the octopus. It does not need to match your primary.

Yes. We change hose lengths in store — just ask when you order. We can also configure a regulator for any technical setup you are running.

That is what we are here for. Come into the shop, call us, or message us online and we will talk it through — on this or any other product, with no obligation to buy anything.
