Regulators

A scuba regulator takes high-pressure air from your tank and delivers it at a pressure you can breathe. The first stage attaches to the tank valve, and the second stage is the mouthpiece you breathe from. A complete setup also needs an alternate air source (octo) for your buddy and a pressure gauge or wireless transmitter.

We carry regulators from Atomic Aquatics, Zeagle, Hollis and XDEEP, along with our own Z90 regulator systems. Piston first stages are simple and durable, which makes them a solid pick for recreational and warm-water diving. Balanced diaphragm first stages keep breathing effort steady as you go deeper. Environmentally sealed models keep cold water and silt out of the first stage, which is worth considering for cooler Southern California dives.

Choose DIN or yoke based on the tanks you use most. Our Montclair, CA staff can help you match first and second stages and set up your hoses. You can also shop first stages, second stages, octos and regulator accessories.

    Scuba Regulator Buying & Setup Guide

    1. Choose between piston and diaphragm designs. Piston regulators are simple and high-performing, while diaphragm regulators are better for cold or contaminated water due to environmental sealing.
    2. Look for balanced vs unbalanced systems. Balanced regulators provide more consistent airflow regardless of tank pressure and depth, improving breathing comfort.
    3. Consider environmental sealing if you plan to dive in cold water or harsh conditions to prevent freezing and internal contamination.
    4. Check hose configuration and port options to ensure compatibility with your dive setup, including octopus, gauges, and inflators.

    A scuba regulator reduces the high-pressure air from your tank to a breathable level and delivers it to you on demand as you inhale underwater.

    The first stage attaches to the tank and reduces pressure, while the second stage is the part you breathe from, delivering air as needed.

    Balanced regulators provide smoother and more consistent breathing performance, especially at deeper depths or lower tank pressures, making them a popular choice for many divers.

    Higher-end regulators often offer improved breathing performance, lighter materials, corrosion resistance, and advanced engineering, but many mid-range regulators perform extremely well for recreational diving.

    If you dive in cold water or environments with sand or contaminants, an environmentally sealed regulator helps protect internal components and improves reliability.

    Most manufacturers recommend annual servicing or after a certain number of dives to ensure safe and optimal performance.

    Yes, regulators are commonly packed in carry-on luggage to protect them from damage, and many models are designed to be lightweight and travel-friendly.

    Key features include breathing performance, durability, weight, environmental sealing, hose routing, and overall comfort during extended dives.
