Scuba diving is a wonderful activity that is consistently increasing in popularity, and everyone can take part no matter where you are in the world.

However, in order to participate in scuba diving, you need some special high-performance diving gear.

scuba regulator is among the essential pieces of a scuba diver’s equipment.

The equipment links together various key components of the scuba gear, including the scuba tank.

It also transfers oxygen from your tank to you, allowing you to breathe effectively while underwater.

Using many elements, we took a look at some popular choices in the market today.

Below are our best picks for scuba regulators.


What We Looked For

It’s essential to examine all the safety and functional features of a scuba regulator before adding it to your scuba gear.

We compared the various features of these brands, how they measure up with cold water and diving depths, as well as diver comfort.

From antifreeze technology to diver controls, how scuba regulators operate can make all the difference in a useful product.

Some factors we examined when recommending the best scuba regulators for 2021 include:

  • Breathability
  • Balanced, unbalanced, overbalanced
  • Weight
  • Number of ports
  • Materials and construction

Is It Easy to Breathe Through?

Scuba divers need enough air while exploring the underwater world.

However, the amount of air one needs varies depending on the individual and the depth of the water.

The decision for unbalanced and balanced dive regulators will depend on your diving style and needs.

How quickly you descend into deeper water will also guide your choice of a regulator.

We tested each product below to ensure it’s easy to breathe through.

You can rest assured that you will have enough air supply while using any of the scuba regulators we list.

Whether you are a recreational diver or seasoned in the water, we have your breathability needs covered.

Regulators can vary between diaphragm models or piston styles.

Diaphragm types can cost you more than piston types and have more moving parts.

Piston regulators can freeze up more often but are cheaper to maintain.

The preference between diaphragm and piston regulators is typically a diver’s preference, although many individuals are partial to diaphragm styles.

Balanced, Unbalanced, or Over-Balanced

Balanced scuba regulators provide equal resistance in the shallow waters and assistance at low depths to ensure comfortable and consistent breathing while diving.

The breathing adjustment is automatic, and many beginner divers prefer balanced regs for ease of use.

Alternatively, unbalanced regulators are not automatic and may not suit all divers because of the increased inhalation effort required in deep waters or when the tank runs low.

Also, there’s another category of over-balanced regulators.

These first-stage regs come with a unique style of diaphragm, allowing a faster increase of interstage pressure in the hose than a traditional balanced regulator.

This should be your best choice for a scuba regulator in 2021.

How Heavy Is It?

You don’t want to add more weight than necessary to your body while scuba diving, as this will limit your enjoyment.

Your buoyancy rate should be positive enough to allow you to float to the surface effectively.

Scuba regulators are made with different materials which dictate their weight.

The total weight of your scuba gear should also reflect your diving intentions and environment.

While 10% of your body weight in scuba equipment is standard, the temperature of the water can also dictate divers to add or subtract four to six pounds of equipment.

Warm water divers should subtract four to six pounds of weight from their diving gear.

This adjustment can be in the form of a lighter wetsuit or one of thinner material.

Alternatively, cold weather divers should add an extra four to six pounds to help maintain core body temperature.

This adjustment will make your diving experience more comfortable.

Some regulators offer considerable weight savings but have some drawbacks.

It’s worth noting that the size and weight of the regulator should be compatible with the size of your face.

You can prevent jaw fatigue by choosing a lightweight regulator.

Titanium regulators are lightweight and allow you to move freely and effortlessly while diving.

Number of Ports

The location and number of ports a regulator has is an essential design aspect you should consider when looking for a scuba regulator.

The ports determine your options to adjust your hose routing.

This is an important feature for cave, technical, and wreck scuba divers.

Also, if you plan to use a pressure transmitter/sensor in place of a mechanical SPG, you should be concerned with the number and location of regulator ports.

Ideally, you need a regulator with more than one port (high-pressure port and low-pressure port).

Other regulators have medium-pressure ports instead of low-pressure ports.

Your choice depends on your needs.

Materials and Construction

Regulator materials will differ between the first stage and second stage.

Typically, the first stage regulators will consist of titanium or chrome-plated brass.

They are easy to service and can be less expensive than second-stage regulators.

Second stage regulators can sport a brass body, titanium, plastic, or a combination of brass and plastic.

They can be more compact than the first stage regulators, aiding in your diving experience.

You also need to consider the outside coating, also known as environmental sealing.

This coating uses alcohol or silicone-based coating to help seal regulators and protect them from salt, sediment, and prevents freezing in cold water temperatures.

This is why the regulator materials are coated to prevent corrosion and damage.

Here, you can consider titanium and chrome-plated brass.

Remember that hard materials like these will outlast plastic options.

Although, you need to thoroughly clean any scuba material after every use to ensure it lasts and continues to work as intended.

Proper cleaning and storage can help extend the life of your equipment.
