Scubapro C370 Regulator White

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.

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.

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.

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.

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.

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.

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.

Scubapro publishes the C370 as the second stage of two complete systems: the MK11 EVO/C370 and the MK17 EVO 2/C370. Because this listing is the second stage only, call 888-701-4017 and we will confirm it works with your first stage and hose. If you are unsure about your first stage or hose fitting, call 888-701-4017 and we will confirm it with you.

Yes. The C370 uses a diver-changeable color frame made of impact-resistant polymer that snaps on and off the front cover, and Scubapro offers six colors: white, graphite, blue, turquoise, yellow and pink. The White version ships with the standard white frame. Note that the current color frames fit the new C370 only and will not fit previous C370 models that use a metal frame.

It is a coaxial Venturi control using Scubapro's Venturi-Initiated Vacuum Assist (VIVA). In the pre-dive position it reduces assisted airflow so the regulator is less likely to free flow at the surface or in current. Switched to dive, it uses the airflow through the case to make inhalation easier. Pair it with the adjustable inhalation effort knob to tune breathing at depth.

An air-balanced valve uses supply pressure to help open the valve, so inhalation effort stays consistent as you go deeper and as tank pressure falls through the dive. Combined with the diver-adjustable inhalation knob and the hi-flow orthodontic mouthpiece, the C370 is built to keep breathing smooth rather than getting progressively stiffer toward the end of a dive.
