How to Choose a Scuba Regulator

When it comes to investing in your own scuba octopus setup, you’ll find that there are a massive amount of options out there to choose from.

As your scuba regulator is such an important piece of your scuba gear set, you should make sure that you get exactly what you need.

Your scuba octopus setup is what allows you to breathe underwater, and if looked after, it should last you a very long time.

With the importance of choosing the right piece of dive equipment in mind, here are a few things to consider before purchasing your own scuba octopus setup:

Scuba Octopus Setup

Yoke or Din – Whether you use a yoke/A-clamp or DIN, connections are an important consideration when buying your regulator. This decision should depend on your dive style, and where you’ll most often be diving and servicing your equipment. For deeper, or more technical dives, DIN regulators are often recommended due to their strength.

Unbalanced or Balanced – Most modern scuba octopus setups come in the balanced form. This is generally preferred, and is definitely recommended for more serious dives. However, balanced setups tend to be a bit pricier.

Unbalanced regulators use piston and diaphragm designs and ‘breathe’ a little harder. Balanced regulators ‘breathe’ evenly across the dive. This is usually a decision based on how much you’re willing to fork out.

Number of Ports –
Ideally, your scuba octopus setup should come with at least two high-pressure ports, and four low-pressure ports. If there are more ports available, this allows you to customize your setup further.

  • Does it include
    venturi/inhalation assist?

  • Is it an environmentally sealed regulator?

  • How much does your scuba octopus setup weigh?

With all of these considerations in mind, it’s important to understand what you are looking for in your gear. As each person has different requirements and preferences, it’s necessary to understand the variety of equipment available, and exactly what it is that you need for your dive situation.

  • Over 18 billion pounds of plastic enters the World’s Oceans every year. That’s enough trash to cover every foot of coastline around the world with five full trash bags of plastic (Every. Year).


  • As well as containing it’s own toxic chemicals, like BPA, plastic absorbs even more potent toxins from other pollutants in the Ocean such as oil, untreated sewage and radioactive waste.


  • Plastic is indestructible and never degrades. Instead it simply breaks down into smaller pieces which accumulate together, en masse.


  • Today, each square mile of ocean has over 45,000 pieces of plastic floating in it.


  • Plastic is mistaken for food and eaten by marine animals. Because it can’t be digested, it fills their stomachs and causes them to starve to death.


  • For those “lucky” individuals that don’t eat plastic, the toxic chemicals present in every part of sea water from plastic, wreck havoc throughout the ecosystem causing changes in animals behaviour, immune systems and reproduction.


  • There are 200 known ‘dead zones’, or areas deprived of oxygen and devoid of life, (area between 1 and 70,000 km²),  in the world ocean, due to plastic: this number has doubled every decade since 1960.


  • Chemicals in heavily polluted waters can make their way back to us and cause serious health issues like reproductive problems, hormonal problems, kidney damage, and nervous system damage.


  • It’s estimated that by the year 2050, there will be more plastic in the ocean than fish (by weight). AND IT’S GETTING WORSE
