Product Information
The TUSA RS1001 DIN Dive Regulator Set pairs the balanced diaphragm R1000 first stage with the S0001 second stage, giving recreational divers a DIN fitting rated to 300 bar/4350 psi, two high-pressure ports, and four low-pressure ports (two standard, two high-flow) for building out a full gear configuration.
Who it is for
This set suits recreational scuba divers who use a DIN tank valve and want a first stage that stays compact and lightweight while supporting left or right-hand hose routing. The cold water insulation system and enhanced HP poppet assembly make it a reasonable pick for divers who get into cooler water and want consistent intermediate pressure as tank pressure drops through a dive.
Key details
- First stage: R1000, balanced diaphragm design, compact and lightweight construction
- Second stage: S0001, with a venturi adjustment lever and an ortho-consciously designed mouthpiece
- Ports: 2 high-pressure ports and 4 low-pressure ports (2 standard, 2 high-flow)
- High-flow LP ports: increase air flow by up to 15%
- Connection: DIN, rated to 300 bar/4350 psi
- Case: lightweight, compact composite
- Configuration: left or right-hand hose routing

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.
Does the TUSA RS1001 come in a yoke version as well as DIN?
TUSA offers the RS1001 as a DIN-rated set (RS1001 DIN, 300 bar/4350 psi), which is the configuration sold here. Check with TUSA or your dive shop if you need confirmation on a non-DIN version before ordering, since this listing specifically covers the DIN fitting.
How many hose ports does the RS1001 first stage have?
The R1000 first stage has 2 high-pressure ports and 4 low-pressure ports, split between 2 standard LP ports and 2 high-flow LP ports. This gives enough connections for a primary second stage, octopus, BCD inflator hose, and a gauge or computer hose, or a drysuit hose if needed.
What do the high-flow LP ports on the RS1001 actually do?
The two high-flow low-pressure ports on the R1000 first stage provide up to a 15% increase in air flow.
Is the TUSA RS1001 built for cold water diving?
Yes, the R1000 first stage includes a cold water insulation system designed to help maintain consistent performance as water temperature drops. It also uses an enhanced HP poppet assembly for added reliability as intermediate pressure shifts during a dive.
