Things to consider when buying the best scuba regulator

Safety

Major brands have high safety standards for scuba regulators. In order to be put on the market, each make and model of regulator must withstand rigorous testing. This is important because an expensive regulator doesn’t necessarily mean that it’s a safer or better option. The price of a regulator is influenced by many things, but safety is not one of them.

Basic regulators are perfect for recreational divers in warm water. The special features apply more to dive professionals, cave divers, cold water divers, and those looking to push the limits of what their equipment can do.

Cold vs. warm water diving

Different scuba diving regulators have different thresholds when it comes to water temperature. When the water is cold, around or below 15°C, it can lead to a free-flowing regulator. If you think you might be diving in cold water, it’s best to pay a little bit more for a regulator that can handle the cold temperatures.

Coldwater regulators are sealed to withstand low temperatures – but they also are best for divers in murky environments, where the regulator could be prone to collecting tiny debris. The same sealing that protects the regulator against cold also keeps particles out.

Balanced versus unbalanced

In general, balanced regulators are better – but they are of course, pricier. An unbalanced regulator breathes more unevenly when divers share air, at depth, or when the tank pressure decreases. Unbalanced regulators also typically cost less to service.

A balanced regulator breathes evenly throughout the dive, no matter the other variables. If you plan to technical dive or dive at more serious depth, it’s worth investing in a balanced regulator.

Piston versus diaphragm

A piston has only one moving part attached to the first stage, so it is easier to service. However, this set-up allows some water into the first stage, so it requires more frequent care to prevent against corrosion. They are also slightly more durable than diaphragm regulators.

A diaphragm regulator is made up of more parts, but is a top choice if its environmentally sealed. A sealed diaphragm regulator tends to last longer in cold water or silty water compared to a piston diaphragm. The issue is that diaphragm regulators tend to be more expensive to service.

Tank mount types

There are two types of tank mounts that vary between regions.

Yoke: This is the most common type of air tank mount. This is the most common type of mount in the world.

DIN: This type of air tank mount is popular among tech divers and cave divers as it tends to have less drag and is more secure. They are also more compact.

Many tanks accept both regulator mounts. If you purchase one type but want to cover your bases, invest in a tank mount adapter.

Breath flow

It might help to think of your regulator like a faucet. Some regulators have an easy, solid airflow. Others have more resistance. Some regulators are adjustable, so you can control the flow of air as you like.

Octopus and hose length

Most regulators are set to have the primary hose and the octopus hose be the same length. Some regulators don’t have an octopus (secondary hose) and some hose lengths are adjustable. More flexible hoses are great if you travel, as they are easier to fold and stow away.

Dive guides and instructors might feel more comfortable diving with a longer second stage should one of their divers need it. Others, like technical divers, might want to focus on being as compact and hydrodynamic as possible.

Mouthpiece comfort

Is the regulator comfortable to carry in your mouth? If it seems heavy at first, remember that it will be weightless underwater. Some mouthpieces are made to allow you to have a natural bite – but they don’t fit every mouth.

FAQ – Frequently asked questions about dive regulators 

What is a scuba diving regulator and how does it work?

A scuba diving regulator works by supplying air from your tank to your lungs through well crafted system. 

How do you use a scuba diving regulator?

You use a scuba diving regulator by attaching the regulator to your air tank. You breathe from the tank through a hose with a mouthpiece attached on the end of it. Scuba diving regulators are also used to inflate your BCD (buoyancy control device). The BCD keeps you from sinking or floating while in the water, allowing you to stay neutrally buoyant.

During your scuba diving course, an instructor will teach you exactly how to use a scuba diving regulator.

What are the parts of a scuba regulator?

A scuba regulator has four main parts:
1) First stage: the part that connects to the air tank
2) Second stage: the part that connects to the mouthpiece
3) Octopus: an alternate air hose
4) BCD inflator hose: supplies air to your buoyancy control device
