Description

Introducing the revolutionary Diving Pro X First Stage Regulator - the ultimate choice for divers seeking top-tier performance in extreme conditions. Crafted with a forged 1st stage body, this regulator ensures maximum thermal performance under water.

Designed with an over-moulded first-stage end cap and environmental diaphragm, the Diving Pro X prevents ice build-up that could lead to free flowing, guaranteeing a smooth and safe dive every time. The ribbed diaphragm clamp and angled HP ports optimize heat exchange and hose routing, while the parallel turret ports enhance hose orientation for improved efficiency.

Built for durability, the Diving Pro X features superb impact protection on both the 1st and 2nd stages, giving you peace of mind during your underwater explorations. The simple-to-use 2nd stage requires no dive adjustment controls, reducing the risk of free flow and allowing for a hassle-free dive experience.

Experience ultimate comfort with the double swivel hose that offers greater freedom of movement, while the patented heat exchanger surrounds the valve mechanism, dissipating cold gas expansion and drawing in ambient water warmth. Tested for Octopus use to 60 meters in cold water, the Diving Pro X is developed in accordance with the United States Navy Experimental Dive Unit extreme cold water test, ensuring reliability and performance in the most challenging environments. Choose the Diving Pro X First Stage Regulator for unparalleled quality and innovation on your next dive.

Features

First Stage

  • Available in yoke or DIN configuration.
  • Suitable for cold water use (below 10°C / 50°F).
  • Unique over-balanced diaphragm design – as the diver descends, the over-balancing feature allows the medium pressure gas in the hose to increase at a faster rate than ambient. This results in superior performance at depth.
  • Over-moulded innovative endcap and environmental diaphragm, a forged 1st stage body offering maximum thermal performance.
  • The 5th 3/8” UNF medium pressure port includes a protective bumper when not in use.
  • Forged first stage body with heat exchanging ribs for maximum thermal performance.
  • Angled HP ports for optimal hose routing and fitting of transmitters.
  • Forged rotating turret with medium pressure ports in a parallel direction for improved hose orientation.
  • Ribbed diaphragm clamp for improved heat exchange in cold water conditions.
  • Double swivel hose for greater freedom of movement and comfort.
  • Tested for Octopus use - EN250A cold water.
  • Nitrox/Oxygen compatible – Up to 40% O² outside the EU (European Union), within the EU anything above 21% O² must use an M26 Connection.
    Second Stage
  • High performance, pneumatically balanced, lever operated poppet valve.
  • Large, diver friendly self-flushing controllable purge button.
  • Front cover with over-moulded elastomer incorporates a formed chromeplated brass plate improving durability of the second stage.
  • Large protective elastomer bumpers on the side and on the top to protect the second stage from impacts and scratches in the most vulnerable places.
  • Reversible second stage for either a left or right hand gas supply configuration.
  • A heat exchanger (patented) which surrounds the valve mechanism, dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water.
  • Comfo-bite mouthpiece.
  • Double swivel hose.
  • Flexible nylon braided hose has better cold water performance than traditional rubber hose.

Frequently Asked Questions

How often does a scuba regulator need servicing?

Follow the interval in your regulator's manual, since manufacturers commonly specify an annual inspection or a set number of dives and many warranties depend on it. A regulator is life-support equipment, so service belongs with a factory-trained technician rather than being attempted at home. Have it looked at sooner than scheduled if you notice increased breathing effort, free-flow, bubbles, or water in the second stage.

How do I rinse and care for a regulator after diving?

Make sure the dust cap is dry and firmly seated over the first-stage inlet before the regulator goes anywhere near water, because water inside the first stage is the leading cause of internal corrosion. Rinse in fresh water without pressing the purge button, since purging while depressurized can draw water back into the second stage. Shake out the water and hang it to dry with the hoses in wide, gentle loops rather than tight bends.

Can I fly with a scuba regulator?

Regulators travel well and are usually best carried in hand luggage where they will not be crushed or lost. A regulator holds no gas of its own, so there is nothing inherently problematic about it on an aircraft, though the airline and security screeners always have the final say. Pack it dry with the dust cap in place, in a padded regulator bag or wrapped in soft gear.

Can I use my regulator with nitrox?

Many modern regulators are supplied as suitable for nitrox mixes up to 40 percent oxygen, which is the widely used recreational industry standard, while anything above that requires dedicated oxygen-clean equipment and procedures. Confirm what your specific regulator's manual states, and follow your nitrox training and your fill station's requirements. Never assume a regulator is oxygen-service clean simply because it looks clean or is new.

What is the difference between DIN and yoke regulators?

A yoke (A-clamp) fitting clamps over the tank valve and is the most common connection across much of the recreational world, while a DIN fitting screws into the valve and is standard in much of Europe and in technical diving. DIN captures the o-ring inside the threads, which many divers consider more secure, but yoke is often what rental cylinders provide. Adapters exist in both directions, so check what is used where you dive before deciding.

What is the octopus regulator for?

The octopus is your backup second stage, carried so you can share air with a buddy who is out of gas, or breathe from it yourself if your primary fails or free-flows. It is normally on a longer, brightly colored hose so it is easy to find and hand over under stress. Secure it in the triangle between your chin and the bottom of your rib cage so it is instantly accessible and not dragging through sand or coral.

How should I store a regulator between dive trips?

Store it fully dry, out of sunlight, with the dust cap in place and the hoses in wide loops rather than tightly coiled. Avoid hanging it by the second stages for long periods, which stresses the hose fittings; laying it flat in a padded bag or hanging it by the first stage is kinder. If it has sat unused for a long stretch, have it checked before your next trip rather than assuming it is ready to dive.
