When it comes time to take your scuba diving experience to the next level, it isn’t just going to new locations to see the underwater scenery. Changing how you dive and interact with the ocean can provide you with a new appreciation for the sea. Utilizing a rebreather on your next dive can give you that newfound experience in the ocean you have been seeking.
What is a Rebreather?
When you use a regular scuba diving device, you breathe in the fresh air from your tank as the CO2 you breathe out gets exhaled through a regulator. A rebreather allows you to breathe your own air continuously throughout the dive with little to no bubbles obstructing your vision. The rebreather removes the exhaled carbon dioxide through the use of a canister of scrubber material.
Then, the rebreather has to replace the used oxygen. This process is accomplished through the use of small tanks that contain pure oxygen or a gas mixture of oxygen and either nitrogen or helium. The system is also equipped with sensors that monitor the oxygen mixture as the dive progresses.
Benefits of Rebreathers
Rebreathers offer divers a variety of advantages over conventional scuba gear.
- Rebreathers offer better gas efficiency over standard scuba breathing equipment. In your standard scuba system, there is a considerable amount of wasted oxygen since divers do not consume all of the oxygen when they breathe through the regulator.
- The rebreather is lighter. Most conventional scuba tanks carry a compressed air mixture that is 78% nitrogen, a naturally heavier gas than oxygen. Since rebreathers replace the used oxygen, you can have a smaller sized tank that is considerably lighter since it is only carrying oxygen.
- Less Decompression. With the lower percentage of nitrogen in the gas mixture, decompression times can be much less if used properly.
- Stealth. Rebreathers produce minimal bubbles during the dive. The lack of bubbles minimizes how much you disturb marine life during your dive. You can observe them in their natural habitat without causing too much of a stir.
