Where and how are you going to use it and which features would you like to have? Which models suit those needs best? After reading countless ratings and reviews and talking to divers, I have put together a list of the best scuba regulators on the market today to make your choice a lot easier. You will also find a quick buying guide as well as reviews to help you make the right choice.

Scuba Regulator Buying Guide – Things to Consider in Choosing the Best Scuba Regulator

Warm versus Cold Water – What is the water temperature where you plan to dive? This will determine if you need a sealed or unsealed regulator.

Unsealed Regulators – For warm water destinations like those in the tropics, almost any regulator will do.
An unsealed regulator means that water can get into the first stage which is alright when diving in warm water. These models are generally cheaper than sealed models.

Sealed Regulators – For cold water diving, you need a sealed regulator. You want the water to stay outside the first stage because at low temperatures the water could freeze inside blocking air flow. An environmental seal also keeps the first stage free from salt, sediment, and other contaminants.

Diaphragm or Piston – The first stage can have either a piston or diaphragm construction. If you are a recreational diver either one is okay, although most divers prefer piston-type first stages because they have fewer moving parts and are considered more reliable. Even though they tend to be more expensive, they are recommended as the better choice for deep diving.

Balanced or Unbalanced – No matter how much air is left in the tank or the depth you are at, a balanced regulator will have a consistent air flow. An unbalanced dive regulator will become harder to breathe from the deeper you go and as the air in the tank decreases. If you plan on deep diving you should get a balanced regulator. Unbalanced ones are a little cheaper, though, and dive shops often use them for rental when deep diving isn’t planned.

DIN or Yoke

DIN Valve – With the DIN system, the regulator is screwed directly into the tank valve. This creates a stronger and more reliable seal, which is also more streamlined. It is used a lot by cold water and technical divers and is more common in Europe.

Yoke Valve – With the yoke valve the regulator is mounted over and around the tank valve. The yoke or A-clamp is the more popular of the two, particularly in North America. It’s also much easier to mount a regulator on a tank with this type of valve.

If you do decide to go with a DIN system, you can get a DIN to yoke adapter that will allow you to use a DIN regulator on a yoke valve.

Number of Ports – A standard regulator setup for recreational diving has a primary second stage, a backup octopus, a high-pressure gauge, and a BC inflation hose. Today most regulators come with 4 low-pressure (LP) ports and 1 or 2 high pressure (HP) ports. The more ports you have, the easier it will be to comfortably set up your gear. Having 2 high-pressure ports can come in handy if you have or plan to get an air-integrated dive computer with a transmitter as you’ll need an extra port where you can attach it.

Diver Adjustable – Higher end dive regulators may have a couple of features that allow you to customize you’re breathing. A Venturi Switch prevents free flows on the surface, while enhancing breathing performance underwater. An Inhalation Adjustment Knob allows you to fine-tune you’re breathing by increasing or decreasing your inhalation resistance with the turn of a knob.
