FROM THE LIGHT INTO DARKNESS
There are many reasons to venture into submerged caves, from scientific survey to exploration or technical sport diving. It is important to understand your motivation for cave diving and make an investment to educate yourself as much as possible to safely dive in these sometimes alien and hostile environments. Training options are available below.
Caves are some of the harshest, but most captivating diving environments
Leaving the Cavern Zone and venturing further into the overhead environment requires more skill, awareness and procedures.
As a cave diver, you will move beyond the daylight zone and enter "The Dark Side" where the hazards increase and the exit becomes further away.
The Intro to Cave Diver course will extend and refine your Cavern level skills and require you to connect onto cave lines and safely navigate the cave while being aware of line markings, exit directions and other teams inside the cave.
Additional emphasis is placed on gas management since you will be further inside the overhead environment and have to allow for emergency procedures to be able to safely exit the cave at all times.

CAVERN DIVER
4 to 5 days
A strong foundation is essential when undertaking overhead training and the Cavern Diver course aims to build exactly that.
A cavern has some formal definitions such as always being able to see natural light, but it requires the utmost attention and concentration to be able to safely navigate this overhead environment. Since direct access to the surface is not possible, there are no less safety measures involved in Cavern Diving compared with further overhead training.
The Cavern Diver course will introduce the concepts, techniques, equipment, hazards and safety measures required for all of your cavern and cave diving - as such, I consider it to be the most important course in the education of an overhead diver.

Feel free to get in touch to discuss your training.
4 to 5 days
FULL CAVE DIVER
Travelling further into the overhead environment with skills and procedures for complex navigation.
As a Full Cave diver, you will be able to increase the duration and complexity of your cave dives through increased gas allowances and navigation options.
The Full Cave Diver course will extend and refine your Cave level skills and require you to perform complex navigation involving directional choices at line intersections (T junctions), gaps, jumps, circuits and traverses.
Additional emphasis is placed on diver skill, awareness, navigation awareness and procedures to be able to safely exit the cave at all times.

CAVERNS, CAVES & CAVE DIVING
Caves are unlike other diving environments
With their fascinating geology and unforgiving nature, there is a huge amount to learn about caves and cave diving. If you are interested in learning more about these places, take a look below to get started.
ACCIDENT ANALYSIS
Most cave diving accidents occur with untrained cave divers - the environment calls for specific equipment, procedures and training.
In 1979, Sheck Exley published the now famous 'Basic Cave Diving – A Blueprint for Survival.'. You can obtain this free of charge from The National Speleological Society-Cave Diving Section (NSS-CDS) here https://nsscds.org/blueprint-for-survival/
Accident analysis was used as a tool to create a set of rules and safety protocols that work in real-life situations.
Research showed that five major factors led to a diving fatality in most cave diving accidents. This led to the development of the five rules of accident analysis.
Among trained cave divers, these rules are still being broken - the most common cause of fatalities among trained cave divers is exceeding the safe depth for their breathing gas. You can read more in depth statistics from the International Underwater Cave Rescue and Recovery (UCCR) here http://www.iucrr.org/cave-diving-fatalities.html
Taking cave level training is the first step to enable you to make safe cave dives, but making regular cave dives to gain experience and keep your skills up is essential.
CAVE ORGANISATIONS
The are several organisations dedicated to cave education, safety and environmental awareness.
NATIONAL SPELEOLOGICAL SOCIETY
The NSS (National Speleological Society) is the largest organization in the world working to further the exploration, study, and protection of caves and their environments, and foster fellowship among cavers. For over 70 years, the National Speleological Society has promoted safe and responsible caving practices, effective cave and karst management, speleology, and conservation.
CAVE DIVING GROUP
The CDG (Cave Diving Group) is the representative body for Cave Divers in Great Britain and Northern Ireland. Its function is to educate and support cavers for recreational and exploratory operations in British sump conditions. Formed in 1946, it is the longest running cave diving organisation and amateur diving club in the world.
NATIONAL ASSOCIATION FOR CAVE DIVING
The NACD (National Association for Cave Diving) is dedicated to promoting a greater appreciation and a full understanding of the special needs required in The Art of Safe Cave Diving. A not for profit, member's based professional cave diver training organisation serving the cave diving community throughout the world since 1968
