Your scuba diving regulator converts the high-pressure air in your tank to a lower pressure to allow you to breathe with ease. Luckily, we have you covered with our wide variety of quality regulators in various styles. We offer both yoke and DIN first stages and DIN to yoke converters to allow you to dive worldwide without issue. We also offer piston and diaphragm designs as well as balanced and non-balanced designs.

Balanced regulators are recommended for depths over 66ft (20 m) and can come with options such as anti-freezing for cold water diving to prevent free-flowing. We offer scuba diving regulator packages and both first and second stages from high-quality and reliable brands. Explore all of our regulator options to find the right regulator for you!

1st Stage Vs. 2nd Stage Regulators

There is a key difference between the available types you have to understand before you get into the water when it comes to your scuba diving regulators. Each regulator has an important role in your next dive, so understanding the differences between them is crucial.

First stage regulators attach directly to the cylinder and help alleviate the air pressure held in the hose. Second stage regulators are commonly referred to as the “demand valve” and are the part that is held in your mouth and delivers the necessary flow. The second stage reduces the immediate pressure on the air in the hose to match the ambient water pressure around you, making it safe to breathe.

These two stages work together to help you breathe underwater and enjoy scuba diving to its fullest. We offer 1st and 2nd stage regulators from the most reliable brands, including Apeks, Aqualung, Halcyon, and Scubapro, for you to choose from.
