CAVE SPECIALTIES

TDI Cave Stage Diver

The TDI Cave Stage Diver course is an advanced cave diving program and is designed for divers who are already certified as Full Cave divers and who want to extend bottom times and/or penetration distance through the use of stage cylinders.
As for all overhead diving courses, students are expected to have a high level of mastery in fundamental skills such as buoyancy, trim and propulsion techniques.
Divers will learn to plan dives with more complex gas management and longer bottom times, as well as multiple methods of cylinder rigging and staging, according to the environment.
Mind-set, stress-management, awareness and conservation of the environment are all very important aspects of any type of diving and represent an important part of the program.
Upon completion of the TDI Cave Stage Diver course, students must show mastery of the specific cave stage diving skills as well as sound and mature judgement concerning dive planning and decision making.

TDI Cave Sidemount Diver

The objective of the TDI Cave Sidemount Diver course is to teach cave divers how to safely use a sidemount configuration in overhead environment, taking in consideration the specific hazards resulting of the combination of both the environment and the configuration.
Sidemount configuration is more versatile and safer to use in caves, but also allows you to go places back-mount doesn’t allow you to, therefor self-limitation and sound judgement in every situation are paramount.
During the TDI Cave Sidemount Diver course, divers will learn their equipment configuration inside-out and will be able to perform quick fix directly underwater in case of equipment malfunction, as well as manipulate their cylinders safely in and out of the water.
The program teaches the proper techniques, protocols and gas management specific to the use of sidemount configuration in a cave environment.
The TDI Cave Sidemount Diver course is also a necessary preparation for more complex forms of diving such as Advanced Sidemount Cave diving.

TDI Advanced Cave Sidemount Diver

The TDI Advanced Cave Sidemount Diver course’s objective is to teach how to safely dive into cave passages so restricted that it becomes necessary to remove equipment to pass. It focuses on the stress management and mind preparation as well as on equipment removal and advanced propulsion techniques.
The TDI Advanced Cave Sidemount course is designed for experienced side-mount cave divers who wish to push their skills and knowledge to the limit. Students will learn how to safely remove equipment in order to pass restricted areas and how to solve equipment problem and failures directly underwater.
A proper mental preparation and the capacity of calm, sound judgement in stressful situations is paramount as the hazards increase in confined passage.
At that level, cave passages become so small that in some cases divers must solve problems without the assistance of the team mates, in zero visibility and in very small caves, which leads to diver’s autonomy in all situations.
The TDI Advanced Cave Sidemount course is an extreme cave diving course and is a real challenge for the student.

TDI DPV Cave Diver

The TDI DPV Cave Diver course’s objective is to teach certified and experienced cave divers how to safely use a Diver’s Propulsion Vehicle in a cave environment. It focuses on the techniques and very high awareness level necessary to properly and safely “drive” a DPV in an overhead environment, as well as the complex gas planning involved in this kind of diving.
Divers will also learn the specificities and the different components of a DPV, as well as proper use and maintenance.
The TDI DPV Cave Diver course is designed for experienced cave divers who wish to extend their penetration range into known cave systems. Also, driving a DPV is simply a lot of fun, and that probably is a good enough reason to engage in this kind of diving in the first place! 
Students will learn how to safely handle a DPV in all situations and handle all related potential mechanical problems. Also, students will learn how to properly plan a DPV cave dive, integrating more complex and conservative gas management in their dive planning.
A proper mental preparation and the capacity of calm, sound judgement in stressful situations is paramount as the hazards increase with the much higher penetration speed.
At that level, a good team dynamics and communication is more difficult to achieve, it is easier to stray away from the line and team’s separation becomes a greater risk too. Therefor, students will be asked to raise their awareness level even higher.
Students must have an extended experience of cave diving and handling stage cylinders prior to start the course.
The TDI Advanced Cave Sidemount course is an advanced cave diving course and is a real challenge for the student in terms of refined basic techniques such as buoyancy control, awareness, communication and trim.

Duration and price

TDI Cave Surveying Diver

The TDI Cave Surveying Diver course is designed for trained and experienced cave divers who wish to collect precise data during a cave dive with the objective to create a “stick map” of the cave system. It is also a necessary preparation step for cartography, which will use the collected data to create a geological map.
The program encourages the use of cave maps for dive planning and increases the diver’s awareness and knowledge of the surrounding environment. It will focus on the safe techniques, procedures and skill necessary, associated with surveying in caves.
Gas management becomes more complex, as swimming and surveying don’t take the same time. Surveying cave divers typically tend to concentrate on the surveying datas and there is a much higher risk of forgetting basic limitations. Therefor, one of the objectives of the course is to raise awareness at a much higher level, as well as the general knowledge of the cave environment.
Modern days surveying divers use different techniques and procedures to gather the datas and produce maps. We, at DZD, will focus on the most practical solutions, such as modern surveying tools and softwares, but also teaching students “older” and more manual methods, in case the technologie fails you…
Skills will include, manual and mechanical data gathering as well as the proper use of softwares and how to exploite these tools efficiently. Also, students will learn basic preparatory techniques, such as knotting lines, advanced line techniques, etc.
Obviously, in order to gather information efficiently, surveying cave diver must display a very high mastery in basic cave diving skills such as buoyancy control, trim and propulsion techniques, as well as a high awareness and knowledge of their environment.
