Regulator Packages — Complete, Matched Air Delivery Systems

Buying a regulator piece by piece works, but it asks you to make several decisions that have to be right together. The octopus needs to be compatible with the first stage. The hose lengths need to suit your configuration. The gauge or computer needs to connect to the right port. Get one of those wrong and you're back ordering adapters.

A package removes that problem. Each of these bundles a first and second stage with the components that complete the system — an octopus, a gauge or dive computer, a regulator bag, or some combination — matched by the manufacturer and configured to work together out of the box. For a diver buying their first regulator, or replacing a whole setup at once, it's both simpler and better value than assembling the same components individually.

At DiveCatalog.com we carry regulator packages from Scubapro, Atomic Aquatics, TUSA, Zeagle, Oceanic, Dive Rite, and Hollis as an authorized dealer for every brand.

The Regulator Package Range

Scubapro Packages

The largest selection here, and the most systematically structured. Every Scubapro package pairs a first and second stage with an R105 Octopus and a Definition Reg 10 Regulator Bag, so the only variable is the regulator itself — which makes comparing across the range straightforward.

The line runs from the MK2 EVO, the piston first stage that has been in production since 1963 with only minor revision, through the compact travel-oriented MK11 EVO, the environmentally sealed MK17 EVO2 and MK19 EVO, and up to the MK25 EVO — Scubapro's premier cold-water-resistant first stage with XTIS freeze protection. Second stage options include the R105, S270, C370, G260, S600, S620Ti, and the all-metal A700, with Carbon Black Tech and titanium variants at the top of the range.

TUSA Packages

TUSA takes a different approach, building packages around what a diver still needs rather than a fixed component list. Options pair a regulator with a DC Solar Link dive computer, a pressure gauge, an SS-0001 Safe Second octopus, or a regulator carrying bag. Regulators across the range include the RS-790 with its cold-water-engineered R-700 first stage, the RS-681, RS-1207, and RS-609U. Every TUSA regulator is ANSTI machine-tested before shipping.

Atomic Aquatics, Zeagle, Oceanic, Dive Rite & Hollis

Atomic Aquatics packages bring the brand's titanium and Monel engineering into complete setups, including the AFC automatic flow control and Comfort Swivel found across their regulator line. Zeagle packages centre on the F8 system co-developed with Atomic, and the Envoy II for divers wanting balanced diaphragm performance at a more accessible level — all Made in USA. Oceanic packages pair regulator sets with Maxdepth gauge consoles. Dive Rite and Hollis round out the range with technically-oriented configurations.

What a Package Typically Includes

• First stage — in DIN or yoke, depending on the configuration you select
• Primary second stage — the regulator you breathe from
• Octopus — the backup second stage for sharing gas, on most packages
• Instrumentation — a pressure gauge, console, or dive computer on some packages
• Regulator bag — padded transport and storage, included with all Scubapro packages here

Exactly what's included varies by package, and it's listed on each product page. If anything is ambiguous, contact us and we'll confirm before you order.

Choosing Your Package

DIN or Yoke?

Most packages are available in both connection types, and it's worth getting right at the point of purchase rather than adapting later. Yoke (INT) clamps over the cylinder valve and remains the standard across recreational rental fleets in North America and the Caribbean. DIN threads directly into the valve, handles higher working pressures, and creates a more secure connection — the standard for technical diving and common across Europe.

Choose based on the cylinders you'll actually dive. If you're unsure, ask your local dive shop what they fill, or contact us and we'll advise.

Frequently Asked Questions

Is a package better value than buying components separately?

Generally yes, and it also removes the compatibility risk. Manufacturers price bundles below the sum of their parts, and the components are selected to work together — correct hose lengths, matched octopus, right port configuration. Buying separately makes sense when you already own part of the system or want a specific non-standard combination.

What is the difference between a first stage and a second stage?

The first stage attaches to your cylinder valve and reduces high tank pressure to a consistent intermediate pressure. The second stage is the part in your mouth, reducing that intermediate pressure to ambient so you can breathe normally at whatever depth you're at. Both are needed, which is why they're sold as a set.

Do I need an octopus?

Yes. An octopus is a backup second stage that lets you share gas with a diver who is out of air, and it's a required part of a standard recreational configuration. Most packages here include one; check the individual listing to confirm.

Can I dive nitrox with these regulators?

Most modern regulators are rated for nitrox up to 40% as supplied, which covers standard recreational enriched air diving. Higher percentages and decompression gases require oxygen-clean equipment. Check the specific product listing, or contact us to confirm for a particular package.

How often will the regulator need servicing?

Follow the manufacturer's stated interval — typically annually or by dive count, though some manufacturers specify longer intervals. Servicing keeps the warranty valid on most brands, and a regulator that breathes correctly is worth maintaining regardless of warranty terms.

Can you build a custom package?

Yes. Call 888-701-4017 or email support@divecatalog.com and we'll put together a package around the specific first stage, second stage, octopus, and instrumentation you want.
