Description
The MTX-RC first stage has been designed to provide optimum cold water performance from it's satin plated brass body with heat exchanging ribs, to the innovative over-moulded first stage endcap and environmental diaphragm. It helps to prevent ice build-up that can cause free-flowing of a first stage in extreme weather circumstances. These features also protect the first stage from impact damage. The diaphragm design provides an over-balancing feature. This allows the medium pressure gas in the hose to increase at a faster rate than ambient, resulting in superior performance at depth.
The first stage has 5x medium pressure ports (4 of which are mounted on a rotating turret for improved hose orientation), and 2 angled high pressure ports. These ports allow for optimal hose routing and fitting of air pressure transmitters. It has a double swivel hose for greater freedom of movement and comfort while diving, and an easy to grip DIN hand-wheel, or over-moulded yoke hand-wheel which require only one hand to release. Tested for Octopus use - EN250A to 60 metres cold water.

Frequently Asked Questions
Find answers to common questions about our gear, courses, and policies.
What is in a standard regulator setup?
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.
Is a regulator a one-time purchase?
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 or unbalanced?
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.
How do I save money without ending up with a bad regulator?
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.
Can you set it up for a long hose configuration?
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.
I am not sure what I need. Can you help?
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.
