Best Scuba Dive Regulators

Dive Regulator

There’s no doubt dive regulators should be right at the top of your list when thinking of embarking on a diving expedition.

Have you considered their real value?

For devices that literally keep you alive under water I’m sure you’ll only be looking at the best dive regulators on the market.

If you’re new to scuba diving below you’ll find a guide of elements to look for before making this investment.

Let’s help you pick the best.

What Components Make up a Dive Regulator?

Before we go any further you need to be aware of what exactly makes up a dive regulator:

  • The first stage: This is the part that connects to the oxygen tank
  • Second stage: This part connects to the mouthpiece
  • Octopus: This is an alternate air hose
  • BCD inflator: It supplies oxygen to your buoyancy control device (BCD)

Now that you know what you’re working with, let’s look at a couple of considerations to note before selecting one.

Basic Do’s and Don’ts

I’ve found a bargain!

Looking for a bargain when trying to buy the best dive regulator might not be a bright idea. The more you spend the easier you breathe. It’s that simple. For instance, cold water regulators will cost more but they offer better free flow because of their specifications.

Expensive is safer

However, never assume buying the most expensive dive regulator you can find on the market means you’ve bought the safest option.

Rather opt for well-known brands. Most major brands have high safety standards. Their regulators go through rigorous tests before they’re put on the market.

Different brands

So your uncle gave you that air hose that’s been sitting in his garage. And all you need to do is find the remaining parts, even if they’re a different brand, right? Not quite.

When it comes to the components of a dive regulator, as mentioned earlier, always use parts from the same manufacturer or brand. This ensures that they’re compatible.

How to Choose a Dive Regulator

Are you Going for a Cold or Warm Dive?

Answering this question will help you select the right dive regulator for the appropriate water temperature.

If you’re diving in cold water opt for regulators which are designed to handle those low temperatures. For instance, cold water regulators have a seal to withstand water temperatures of around or below 15°.

Balanced or Unbalanced Regulators

Balanced regulators

This regulator makes you breathe evenly throughout a dive regardless of other variables. For instance, if you and your diving buddy are thinking of sharing a dive regulator, you can both breathe easily without difficulties.

Unbalanced regulators

Breathing using an unbalanced regulator becomes a challenge if you plan on going deeper into the water. If the tank pressure decreases, breathing is negatively impacted. The only upside to unbalanced regulators is they cost less to service.

So, in a nutshell, balanced regulators are a bit on the pricy side. But we’re pretty sure parting with a few extra dollars to have a regulator that won’t compromise your breathing is worth it, don’t you think?

Breath Flow

How important to you is regulating the amount of oxygen the regulator gets into your body?

Some regulators give you an easy, steady flow, while others offer more resistance. If, however, you prefer to control the airflow opt for an adjustable dive regulator.

How Comfortable is the Mouthpiece?

Even though this device is crucial for your breathing you really don’t have to sacrifice on comfort. How comfortable is the regulator to carry in your mouth?

Don’t panic if it might seem heavy when you try it on at home. As soon as you go underwater it becomes weightless. That’s the beauty of science!

Some mouthpieces are designed to allow you to have a natural bite. However, they don’t fit every mouth.

Piston or Diaphragm

Selecting between these two will depend more on your budget and personal preference.


A piston has only one moving part attached to the first stage so it’s easier to service. Unfortunately, this setup allows for some water to go into the first stage, so extra and frequent care is required to avoid premature corrosion. If durability is your main priority then I’d recommend the piston regulator.


A diaphragm is made of more parts compared to its piston counterpart. If you’re environmentally conscious, opt for a sealed diaphragm regulator. Not only is it environment friendly, it lasts longer in cold or salty water. You must however be prepared to spend a little more when servicing it.

Attributes that Differentiate these Dive Regulators

Different dive regulators come with different attributes depending on what you want to use it for.

Over balanced

What does it mean if the first stage is over balanced? This means you’re able to enjoy excellent performance from the regulator because it increases your air supply the deeper you go.


Different first stages in regulators have different pressure ports to fit your hose in. Most regulators have one high-pressure port and four low-pressure ports.

What you must know is that a high-pressure hose is too big to fit in a low-pressure port. You need to establish whether the regulator has different port sizes to avoid errors.

Compact Second Stages

Is comfort one of your major concerns? Are you planning on being under water for a while?

The size of the second stage will go a long way in alleviating some of your concerns. Some regulators come with compact second stages and this will mean a lighter physical weight resulting in reduced jaw fatigue.

A regulator with a smaller second stage will also mean less dead space and thereby reducing any potential carbon dioxide build up.

Now let’s find you perfect choice.
