A short history of Rebreather cave diving

The brief history listed below is by no means complete and will grow over time. Many CCR and P-SCR Rebreather cave dives are being conducted world wide on a daily basis. As Rebreathers are the perfect tool for deep diving purposes it seems natural to see them employed during deep cave diving and exploration.

1949 At the Wookey Hole cave located in the United Kingdom a group of cave explorers used Oxygen CCR Rebreathers

1956 At Wookey Hole a Semi Closed Nitrox Rebreathers was used while exploring beyond the point in the cave designated as "Wookey 13." In 1960 again using Rebreather technology cave explorers reached Wookey Chamber 15 at a depth of 71 feet / 21 meters.

1980 At the Fountain de Vaucluse Jochen Hasenmayer is using his own designed and buit Closed Circuit Rebreather, the Speleo-Twin / STR 80 double unit and reaches 434 feet - 132 meters depth.

1989 At the spring of Doux De Coly located in France cave explorer Olivier Isler refined his RI 2000 Semi Closed Rebreather (a unit built and designed by Olivier Isler and electronics engineer Alain Ronjat) that later developed into a triple redundant Rebreather unit with three separate Rebreathers. Major achievements in Italy (Cogol dei Veci) and France (Ressei, Doux-de-Coly and Gourneyras) were realized with the use of the RI 2000, the first Rebreather conceived especially for cave diving exploration. To date the Doux De Coly has been pushed back with the help of a team of British, French and Swiss divers and the RI 2000 rebreather to an incredible 27,880 feet / 8,500 meters at 164 feet – 50 meters.

1994  During a deep dry cave exploration project in Sotano San Agustin, part of the Systema Huautla, in Oaxaca, Mexico a CCR Cis Lunar MK4 Rebreather was used to explore water filled sumps. The expedition was covered by the National Geographic magazine in September 1995.

1995 Cave divers of Australia conducted a series of Rebreather cave dives on modified SCR Dolphin Rebreathers to conduct their lengthy cave penetration.

1995 Cave explorer Jochen Hasenmayer of Germany, after being paralyzed due to a diving accident, invented and constructed his extremely small and compact mini submarine, the Speleonaut. The mini sub allows him to enter water filled caves while he is breathing from a Rebreather live support system. Jochen Hasenmayer penetrated the Blautopf cave in Germany for over 5,900 feet / 1,800 meters with the use of his Speleonaut submarine.

1997 During preparations to the Wakulla II project CCR cave dives where conducted in Madison Blue Spring, Florida, USA using CCR Cis Lunar MK5P Rebreathers.

1998 At Wakulla Spring the WKPP team set a world's cave penetration record by traveling 18,000 feet / 5,487 meters from the entrance of Wakulla Springs into one of its primary conduits using Halcyon P-SCR Rebreathers at  a depth of over 240 feet - 70 meters.

1998 Wakulla Spring was host to the Wakulla II mapping and exploration project utilizing Cis Lunar MK5P CCR Rebreathers that developed into the redundant double Cis Lunar MK5P unit. During the project saturation diving techniques and hardware was used such as a surface decompression chamber and a diver transfer bell. The cave mapping unit consisted out of 32 sonar guns that created a 3-D computer generated cave map. Bottom times of over 5 hours at a depth of over 240 feet / 70 meters where achived.

2000 During the Yucatan 2000 cave exploration project conducted in the central Yucatan the Cenote Sabak Ha ( Turbid Water in Mayan Language ) was explored to a depth of 400 feet / 120 meters using CCR Inspiration Rebreathers. Dzonot Tia Malo was explored and its cave passages surveyed using a CCR Inspiration Rebreather. 

2000 - 2004 Within the cave system of Dos Ojos located in Q.Roo, Mexico lays Cenote " The Pit " which was explored by CCR Inspiration and Cis Lunar MK5P Rebreathers to a depth of 391 feet - 119 meters.

2004 Separate cave systems that where later included into the Ox Bel Ha cave system Q.Roo, Mexico where explored and surveyed with the use of CCR Inspiration Rebreathers.

2005 A world record traverse was conducted south of Tallahassee, Florida, USA. The world record for a traverse of this type is now held by the Florida diving team WKPP from Sullivan Sink to Cheryl Sink using RB-80 P-SCR Rebreathers. There are a few other caves in the world that may contain something of a traverse, but nothing like this one of 14,000 feet / 4,268 meters long and at a depth of 216 feet / 66 meters.

2006 CCR Rebreather cave dives have been conducted in Eagles Nest, Florida, USA with various Rebreathers such as the CCR O2ptima and Megalodon to a depth of 260 feet - 79 meters.

2005 Mystery Sink in central Florida, USA was explored with the use of CCR Megalodon Rebreathers reaching a depth of over 400 feet - 120 meters.

2007 During the exploration of Weecki Watchi Springs in Florida a CCR Optima diver reached a depth of 400 feet - 120 meters.

2007 During a deep cave exploratory and cave survey project in the Sra Keow Caves located in Thailand deep cave dives where conducted using the CCR Megalodon Rebreather.

2009 CCR Rebreathers are used for the ongoing Wikiwatchi deep cave exploration project in Florida.

Countries where Rebreathers are used on a regular basis for cave diving are, but not limited to: USA, Mexico, Bahamas, Belize, Brazil, Dominican Republic, United Kingdom, France, Switzerland, Italy, Croatia, Spain, Finland, Germany, Norway, Thailand, Philippines, Australia and growing.
