How to Choose Your First Regulator

Picking your first regulator is one of the most important gear decisions you’ll make as a new diver. Walk into any dive shop and you’ll be confronted with a wall of chrome and rubber, price tags ranging from $200 to $2,000, and enough acronyms to make your head spin.

The good news: for recreational open-water diving, you don’t need to spend a fortune. You need a regulator that breathes smoothly, fits your budget, and can be serviced by your local shop. This guide walks you through exactly what to look for.

First Stage vs. Second Stage

A regulator is actually two devices working together. The first stage attaches to your tank and reduces high-pressure air down to an intermediate pressure. The second stage is the part you breathe from — it delivers air on demand at ambient pressure. Most recreational regulators are sold as matched sets; buy them together for optimal performance and easier servicing.

Balanced vs. Unbalanced

Unbalanced regulators are less expensive but breathing effort increases as tank pressure drops. Balanced regulators deliver consistent airflow regardless of tank pressure or depth — a noticeable improvement, especially on long dives. For most new divers, a quality unbalanced reg is perfectly fine. If you’re diving deep or frequently, step up to balanced.

Serviceability Matters More Than You Think

The best regulator is one that gets serviced regularly. Buy a brand your local dive shop carries parts for — exotic brands that require factory service can leave you grounded for weeks. At Scuba Shack, we stock and service Scubapro, Atomic, and Mares, so we can turn around service quickly for those brands.

Our Pick for First-Time Buyers

Stop into Scuba Shack and breathe-test a few on the bench before you buy. We carry demo models specifically so you can feel the difference between entry-level and mid-range before committing. Our staff can also match you to a reg based on the type of diving you plan to do — cold New England waters versus warm Caribbean trips have different demands.
