What Is a Scuba Diving Regulator?
If you have any prior diving experience, you will have heard of a regulator or “reg” before. But if you’re looking to buy your own regulator outright, it helps to understand exactly what this important piece of kit does.
A diving regulator is a device that allows scuba divers to breathe compressed air from the tank while underwater. It reduces the high-pressure air from the scuba tank to a breathable pressure and delivers it to the diver’s mouthpiece. This process allows divers to inhale and exhale air as they explore the underwater world.
The regulator typically consists of several components, including a first stage, a second stage, a hose, and a mouthpiece. Some regulators may include additional features like alternate air sources or gauges. Regulators can come in various types and designs, each with its own unique advantages and disadvantages.
Choosing the right regulator for your needs and preferences is crucial for a safe and comfortable diving experience.
Why You Should Buy a Scuba Regulator as a Beginner
If you’re a beginner diver, you may wonder if buying your own regulator is necessary or even possible. In short, buying a regulator is absolutely possible and highly recommended if you will dive often!
Here are some reasons why you should buy your own regulator as a beginner:
Works Out Cheaper
Buying a regulator is essential if you see yourself doing a lot of diving in the future. Renting regulators is an excellent way to figure out what type of regulator you prefer, but it can quickly add up in cost. Purchasing your own is a much more economical solution in the long run.
Improved Comfort and Safety
Having your own regulator means you’ll be able to get a more comfortable fit. The mouthpiece and hose of a regulator can be adjusted to suit your individual needs. This is especially important for your safety, as having the right fit is essential for proper breathing.
Increased Convenience
Having your own regulator also means you don’t have to go through the hassle of renting or borrowing one every time you dive. You always need a regulator when diving – so having your own ensures you’ll be prepared for every dive!
More Hygienic
Finally, owning a regulator is much more hygienic. When renting a regulator, it’s impossible to know who has used it before you and if it’s been adequately cleaned and maintained. Having your own regulator eliminates these risks and ensures you’ll always have access to clean, safe gear.
Factors to Consider When Choosing a Scuba Diving Regulator
When choosing the right regulator, there are several important factors to consider. Here are some of the most essential ones:
Diving Environment
The type of diving you plan to do will significantly impact your chosen regulator. One big factor to consider is the temperature of the water you’ll often dive in. There are two regulator choices that are best suited for different environments: unsealed and sealed.
Unsealed Regulator
When you’re diving in warm, clear water, an unsealed regulator can be a great choice. It’s designed to work in environments where the risk of dirt and debris entering the regulator’s first stage is low. This means an unsealed regulator is perfect for places where the water is clean and free of debris. The other consideration is temperature. If you are planning to dive in cold water, having a sealed regulator will prevent water from freezing inside the regulator which leads to freeflowing.
Sealed Regulator
If you’re serious about scuba diving and want the best equipment for your underwater adventures, you’ll want to consider a sealed regulator. A sealed regulator is completely enclosed, so the first stage is protected from contaminants like sand, salt, and debris. This makes them perfect for diving in cold or contaminated water environments, where the water could freeze in your regulator.
While the differences between sealed and unsealed regulators are clear, the price difference may also affect your decision-making process. Sealed regulators cost more than unsealed ones, so an unsealed regulator may be better if you’re on a budget.
Type of Regulator
Aside from sealed and unsealed, there are a few other options when choosing a regulator.
Different types of regulators cater to different kinds of diving and have their own unique advantages. For example, balanced and unbalanced regulators deliver air to the diver differently. Balanced regulators maintain consistent airflow to the diver, regardless of the depth, while unbalanced regulators tend to require more effort to breathe at greater depths.
Additionally, regulators can be divided into diaphragm and piston types. Diaphragm regulators are generally more reliable and may require less maintenance, while piston regulators tend to deliver air more efficiently.
When choosing between these types, it’s essential to consider your diving style and preferences.
Total Budget
It’s important to consider your overall budget when choosing a regulator. Regulators can range from basic models to more advanced ones with extra features. As a beginner diver, going for the cheapest option may be tempting – but it isn’t always the best choice.
If you’re planning on diving often, it’s worth investing in a better quality regulator that will last you for years.
Personal Fit and Comfort
Your regulator will be in your mouth for extended periods, so you’ll want to ensure it feels comfortable and doesn’t cause jaw fatigue. Look for regulators with a mouthpiece made of a soft, pliable material that fits comfortably in your mouth.
You should also consider the size and shape of the regulator, as a bulky or poorly designed regulator can cause discomfort during your dive. The flexibility and length of the hose is also a factor to consider. The hose should be long enough to allow for comfortable movement – without getting in the way.
Getting feedback from other divers before making a purchase is a good idea. Always read reviews when purchasing online and, if possible, consider renting a regulator before you buy. This will help ensure that your chosen regulator is right for your needs.
Overall Performance
When it comes to choosing a scuba diving regulator, performance is a critical factor to consider. After all, you want a regulator that delivers air smoothly and consistently throughout your dive.
Not all regulators are created equal, and some perform better than others. Some regulators may require you to breathe harder to get air or deliver more air than others – which can impact your bottom time and overall enjoyment of the dive.
As you evolve as a diver and become more experienced, you’ll understand what level of performance suits your needs. For now, consider what you liked/disliked about any regulators you’ve previously used and consider that when purchasing.
Number of Ports
You should pay attention to the number of ports on the regulator. Most regulators typically have two high-pressure ports and 4 low-pressure ports. The more ports you have, the more accessories and equipment you can connect to your regulator. This will be useful when you eventually upgrade your gear and want to add more items to your setup.
Regulator Weight
The total weight of your regulator will directly affect your comfort while in use and also how easy it is to travel with. Regulators aren’t usually too heavy, but it’s worth considering if you plan to travel with yours. The size and construction will impact the weight, so look for regulators with lightweight materials and a streamlined design – without sacrificing performance.
Brand Reputation
Look for well-established brands with a reputation for producing high-quality regulators and providing reliable customer support. Your scuba diving regulator is incredibly important, so it’s worth investing in a brand that stands behind its products.
Understanding Scuba Diving Regulators
A scuba diving regulator comprises several components, each serving a specific purpose. You must understand how a regulator works to make an informed decision when choosing which to purchase.
Here is a beginners guide for the basics of regulator function and operation:
First Stage
The first stage attaches to the scuba tank and reduces the high-pressure air in the tank to a pressure suitable for breathing. It serves as the primary source of air for the regulator, delivering air to the second stage and other components of the regulator system.
Second Stage
The second stage is the part of the regulator you put into your mouth. It’s responsible for delivering air to the diver at a consistent, safe pressure when you inhale. Along with the mouthpiece, the second stage will feature a purge button. The purge button is a feature you press to clear any water from the second stage before taking a breath.
Some regulators also feature an adjustment system that allows full control over the second stage’s delivery.
Octopus/Alternate Air Source
An octopus, or alternate air source, is a secondary second-stage regulator. It’s connected to the first stage via a low-pressure hose and allows you to share air with another diver in an emergency situation. It is also used as a backup if your primary regulator fails.
Yoke or DIN
The yoke or DIN connection is the attachment point between the first stage and the tank valve. Yoke connections fit over the tank valve while the DIN connection screws into it. The type of connection used will depend on the type of diving your regulator is best suited for.
Hoses
Scuba regulators have a few hoses, with each serving a different purpose. Low-pressure inflator hoses feed your buoyancy control device (BCD) and/or dry suit if needed. A medium-pressure hose connects the mouthpiece to the second stage, and a high-pressure hose is used for your gauge.
Submersible Pressure Gauge (SPG)
The SPG is a crucial component of the scuba diving regulator. It allows you to accurately measure the amount of air in your tank so you can plan your dive accordingly. Your SPG is connected to the first stage via a high-pressure hose.

Beginner Tips for Choosing the Right Regulator
Even with all the information available, choosing a scuba diving regulator can be intimidating. Here are some tips to help you narrow down your choices and make the right selection:
Make Sure Replacement Parts are Readily Available
When choosing a regulator, make sure the replacement parts are readily available. Some brands are lesser known and not as widely sold, meaning you may have difficulty finding parts when needed.
Consider a Balanced Regulator
Balanced regulators provide consistent airflow throughout your dive, regardless of your depth. This can be helpful for novice divers who may not yet be familiar with adjusting their breathing based on their depth. Balanced regulators tend to be more expensive, but the added cost is often worth it.
Check the Warranty
A good warranty can give you peace of mind and protect your investment. Look for a regulator with a comprehensive warranty that covers any manufacturer defects or issues.
Choose What’s Best for You
When choosing a regulator, it’s important to consider the type of diving you will be doing. Do your research and read reviews to understand which regulators are best suited for your needs. Don’t be tempted by the cheaper options if they don’t meet your diving requirements or the latest model if it isn’t necessary for your diving.
Ultimately, it’s important to choose a regulator that best fits your budget, preferences, and diving needs.
