Scuba Regulator Parts You Should Know

If you buy the best budget scuba regulators for under $300, you need to learn more about its parts. Here are some of the essential details you should know.

First Stage

The first stage, the scuba regulator, regulates the airflow from your scuba tank in stages when the air goes from the tank and pressure ports until it reaches the diver.

As the name suggests, this is the primary connector you set up to your scuba tank. Its work reduces the high pressure of the air coming from the tank to a lower intermediate pressure.

The lower intermediate pressure is still not safe for humans to breathe directly. As such, there is the need for a second stage to reduce it further.

Primary Second Stage

This stage is in the diver’s mouthpiece. The airflow at this point will be at a lower pressure. During this second stage, the pressure is reduced to an ambient pressure from the intermediate pressure of the previous stage.

The ambient pressure is equal to the water or pressure surrounding the diver, and this should make it safe for the diver to inhale the air directly with dynamic flow control.

It is worth noting that there are two-second stages, and the primary second stage is attached to the standard open water regulators.

Alternate Second Stage

This stage is treated as an alternate air source or, as some would call it, buddy regulator or octopus. It functions just like the primary second stage mentioned above.

This second stage aims to serve as a backup if there is an emergency with pressure ports or when a diver has to share the air with another diver.

For ease of identification, you will find this stage being brightly colored.

Submersible Pressure Gauge

It is also commonly referred to as SPG. This part aims to help the diver monitor the amount of air remaining in the scuba tank. The last thing a diver wants is to run out of air while underwater. So this SPG will be connected to the first stage by using a high-pressure hose to handle the air’s immense pressure from the tank.

Another option for this would be using a dive computer. This computer aims to provide you with real-time data and a sharper accuracy of the remaining time before the air supply runs out.

Low-Pressure Inflator Hose

A low-pressure inflator hose is another essential part of a regulator and pressure ports. This hose is vital for carrying the intermediate air pressure onto the Buoyancy Compensator inflator from the first stage. To fill this inflator, the diver has to press a button that activates the pressure ports.

Now that you know more about the various parts to expect with the best scuba regulator under $300, it is right to look at the available products. Let us look at some of the top regulators you can buy below.

Buying Guide for the Best Scuba Regulator under $300

The Type of Diving

Before you can buy the best scuba regulators under $300, you should always consider what type of diver you are first.

You could be a tropical recreational driver or a more technical and advanced driver who prefers diving in cold water, deep diving, and many more.

For someone who does tropical warm water diving, then any scuba regulator should work fine for them. However, things are different for someone who does cold water diving. Such a person needs a better cold water diving regulator with more features to handle any high-pressure environmental conditions.

Sealed or Unsealed

Depending on where you dive, sometimes you have to consider if the regulator is sealed or unsealed. A sealed diving unbalanced regulator will prevent water from freezing in the first stage, thus blocking the air from flowing to the next stage. The same seal is vital to avoid sediments, salt, and other contaminants entering the first stage. This type of scuba regular will be ideal for cold diving.

On the other hand, the unsealed balanced regulator is for tropical dives, and it does not matter whether the water inflates the first stage as it would still work. You should find them being cheaper than their sealed counterparts.

Unbalanced or Balanced

You will also come across terms such as balanced or unbalanced. A balanced scuba regulator provides you with consistent airflow regardless of the remaining air supply or the depth at which you are.

The unbalanced regulator will keep on reducing the airflow and high pressure depending on the depth. This might make it difficult for you to breathe whenever the air supply is low or when you go deeper into the water.

A balanced regulator might be more expensive, but it is worth the investment to help you breathe better underwater.

Diaphragm or Piston

Depending on the model, some might have a piston or diaphragm construction. The piston construction will have fewer moving parts and thus making it more reliable. It is a top choice for deep divers or cave divers.

The diaphragm first stages will be cheaper and primarily designated for recreational divers.


It is important to feel comfortable while breathing underwater. It comes down to the comfort you get with a scuba regulator, and the mouthpiece primarily determines the comfort. You should never overlook this feature, as it might make your diving experience better or worse.

Look at how hard or easy it is to maintain the bite the whole time you are underwater. Also, if you breathe, is there any noise? These are the questions you need to ask if you hope to end up with a comfortable scuba regulator.


The best scuba regulators under $300 should be safe, comfortable, and durable for you to enjoy diving as a hobby. We have reviewed multiple models above, showing that you can get the best scuba regulators even when on a budget. Check out the buying guide to learn more about the critical features to consider to end up with the proper scuba regulator for your needs.
