Aim
Clear a regulator while underwater using both the exhalation and purge button methods and resume breathing from it.
Reason to Learn
This basic skill is taught so that you know how to clear water from your regulator whenever you need to put it back in your mouth while underwater. You will need to do this while sharing air with a buddy or in the unlikely event that your regulator is knocked from your mouth.
Difficulty: Easy
Time Required: One minute or less
Here's How:
- Inhale normally from your regulator.
- Holding the regulator with your right hand (as pictured) remove it from your mouth. Hold it with the mouth piece facing down
- While the regulator is out of your mouth, slowly exhale by blowing small bubbles.
- Place the regulator back in your mouth.
- You will now clear the regulator using one of these methods:
- Exhalation method: Sharply exhale into the regulator.
- Purge button method: Use your tongue as a splash guard by placing the tip of your tongue on the top of your mouth behind your teeth, or by covering the hole in the regulator with your tongue. Push the purge button on the front of your regulator gently.
- Exhalation method: Sharply exhale into the regulator.
- Cautiously inhale. Normally the regulator will be clear, but there may still be a small amount of water in the regulator. Breathe carefully from the regulator just in case. If water remains, repeat step 5.
- If all is clear, breathe normally and give your instructor the OK sign.
Tips:
- Remember to continuously exhale while the regulator isn't in your mouth.
- If the regulator begins to free-flow (air comes gushing out) when you take if out of your mouth, either turn it so that the mouth piece is facing down or put your finger over the hole in the mouth piece. Using either method the free-flow should stop.
