Ever wondered what it feels like to dive without bubbles?20 Jul 2017
…find out with Prodivers Kuredu and their rebreathers.
Thought rebreathers were only for technical divers? Think again! Rebreathers are no longer the domain of techies; recreational divers are getting in on the action too! Rebreathers, in their basic form, have been around for more than a century and were mostly used for rescue work in the mine industry.
What is rebreather diving?
Rebreathing is diving with a closed-circuit breathing apparatus that recirculates the gas you have already used by removing the carbon dioxide metabolic product with oxygen. The diver needs to carry only a fraction of the gas that is needed for regular open-circuit scuba diving. Recycling at its very best!
What are the advantages of diving with a rebreather?
- Economical use of gas
- Longer dive time possible with less equipment
- Longer no-decompression limits
- Diver’s metabolic rate is independent on ambient pressure (depth), so oxygen consumption rate does not increase with depth, unlike open circuit diving where inhaled gas increases with pressure and the volume of a breath stays the same
- Except on ascent, rebreathing produces no bubbles which makes less noise and doesn’t startle or scare fish away, allowing divers to get closer to marine life and to experience unforgetable wildlife encounters and, ultimately, better opportunities for photography
- Limits diver’s heat loss at depth due to breathing warm recirculated air – it’s less chilling and reduces risk of hypothermic tendencies
- Breathing more humid air reduces risk of dehydration
Want to give it a try?
Prodivers offers Rebreather Try Dives as well as the TDI (Technical Diving International) Inspiration and Evolution Closed Circuit Rebreather Diver course.
The course introduces you to rebreather diving to a maximum depth of 30 meters using air as diluent and lets you experience things you never imagined possible as a scuba diver.
To enrol in the TDI Inspiration and Evolution Closed Circuit Rebreather Diver Course, you must:
- – Be an Open Water Diver
- – Have Nitrox Diver Training
- – Have a minimum of 20 logged dives
- – Be at least 18 years old
