 Buyer’s Guide

There are many regulators on the market and brands that are constantly improving their products to get to the top. So before you take the dive to purchase a regulator, there are some things you should consider to make sure you are getting the regulator that will fit your needs perfectly.

Regulator Parts

Before you consider anything, the most important thing for you to know is that different parts that make up a regulator, what their function is and how they all work in conjunction with a scuba mask.

A regulator is made up of a first and second stage that are attached together by an air hose. The first stage of the regulator is the part that you connect to your air tank. Its responsibility is the take the high-pressure air – which is usually 3000 PSI – from the tank and drop it down to a lower pressure that is usually called ‘intermediate’ pressure. The first stage supplies and directs air to the second stage of the regulator through the air hose.

The second stage of the regulator is responsible for transporting the air from the tank into your mouth at the right pressure for breathing. The second stage drops the pressure down even more until it reaches what is called atmospheric temperature. A good regulator will balance the air to the pressure of the water around you, allowing you to inhale.

Water Temperature

It’s important to know what type of water temperature you’ll be diving in when considering which regulator to buy. There are regulators that are designed to work better in cold water than in warm water and vice versa. Although many regulators usually work well in both conditions, if you’re traveling to a place with extreme temperature conditions, you may have to think hard about your choice, or you may end up with a regulator that will crack under the pressure.

Knowing the water temperature may also determine whether you need an unsealed or sealed regulator. Unsealed regulators allow water to get into the first stage of the regulator but will not let it into the second stage. These type of regulators are not suitable for cold water. Sealed regulators are optimum for cold water use as they don’t allow water into the first stage.

Balanced vs. Unbalanced

Most divers will prefer a balanced regulator as it provides consistent airflow regardless of the amount of air left in the tank. Unbalanced regulators cause it to become harder to breathe as the air is depleted from the tank.

Diaphragm vs. Piston

The first stage of the regulator can be designed in either a diaphragm or piston design. They control the air pressure from high to moderate during the first stage. Pistons are more favored by divers for their reliability as they have fewer moving parts. They are also much more cost-effective in terms of maintenance. This doesn’t mean to say the diaphragm doesn’t perform as well as the piston design. They both work extremely well, but it is up to you to figure out what you prefer best.

DIN vs. YOKE Valve

These determine where the regulator is placed in relation to the tank. A DIN valve will connect the regulator directly to the tank which may provide a stronger seal. A YOKE valve is screwed over the tank and is the most common form used around the world.

Number of High and Low-Pressure Ports

Depending on your needs or what you are doing while you’re diving, the number of ports may be of importance to you. Generally, it’s much more comfortable to set up your gear when you have more ports. The average number of ports a regulator provides is 4 low pressure and 1-2 high-pressure ports.


Being able to dive with comfort is probably the number one thing you want in a regulator. If you’re a traveler, you want something that is going to be light to carry around – not something that is heavy, bulky and tires you out even before you get into the water. One of the top factors that determine a good regulator is how easy it is to breathe through. Does it sit comfortably in the mouth and does the airflow provide for an effortless breathing experience on your part with minimal to no jaw fatigue?


Surely you’ll want to buy a regulator that not only works well but will last you many dives. A regulator that is durable enough to withstand the elements such as salt, ice, dirt and will be resistant to things such as corrosion or is built with technology that helps to extend the seat life of your regulator. Purchasing a regulator that is durable will mean you won’t have to spend money servicing or buying a new one.

Consistent / Reliable

Not only do you want a regulator that is comfortable and able to withstand the harsh elements of the outdoors, you want a regulator that you know you can trust to work time and time again. Products need to be tried and tested for reliable and consistent performance and the following products are some of the best in terms of their performance.
