Second Stage Regulators

A regulator ensures that you can breathe normally underwater. It consists of a first stage and a second stage, combined with a hose. The second stage is the part you place in your mouth, allowing you to breathe, and it reduces the pressure from the hose to the pressure of your surroundings.

Adjustable and Non-Adjustable

Adjustable second stages have the ability to control the breathing resistance. This means you can adjust how easy or hard it is to inhale.

Balanced and Unbalanced

Most second stages nowadays are balanced. This means the second stage provides consistent performance, regardless of your depth or the pressure in the dive tank.


Venturi is the airflow in the second stage from the valve to your mouth. With an adjustable venturi regulator, you have a lever that allows you to adjust the airflow yourself.

Purge Button

A purge button allows you to expel water from the regulator.

At Lucas Divestore, we provide advice on the best second stages for your regulator. Visit our store in Nijverdal or get in touch with us for personalized guidance.
