CAVE diving

Cave Diving combines water, darkness, and overhead environment. These factors are considered stressful factors for a human being. Cave training takes time and practice, someone  should understand the importance of a concept and attitude, as good judgement, mature, and humble with his peers, teams members, and the caves systems.
WDT Dive teaches NSS/CDS and IANTD cave diving in order to cover standards and programs. To get both certifications we will provide you both agencies student materials, exams, and skills. 



CAVERN DIVER

Cavern diver program is designed to develop cavern diving skills within the limits of light penetration and to insure that the divers are aware of self-responsibility and capable of risk management in an overhead environment.


Equipment Requirements

IANTD Cavern Diver Student Kit, NSS/CDS Cavern manual. A dual-outlet (H or Y) valve is recommended. A 40-inch (1-meter) long hose is to be attached to one of the second stages on the primary gas supply. It is recommended a long hose (5 - 7 feet / 1.5 - 2 meters) in length for gas sharing be carried by each diver. Primary reel and/or safety reel.

 Two lights.

INTRO-CAVE DIVER

Intro cave diver program is designed to provide an introduction to the cave diving environment for Sport Divers.


Equipment Requirements

IANTD Cave Diver Student Kit. All students must be taught the concept of gas matching.  All bottom mix tanks must be equipped with dual-outlet (H or Y) valves or double tanks with dual orifice manifold. A 5-foot (1.5-meter) to 7-foot (2-meter) long hose must be attached to one of the second stages on the primary gas supply.  A primary reel and a safety reel. Three lights: one primary light and two backup lights.


APPRENTICE CAVE DIVER

Apprentice Cave diver program is designed to provide a coverage of most of the academics and emergency skills required for full cave diving.
Students will make some simple explorations off the main line.

(Full) CAVE DIVER & TECHNICAL CAVE DIVER

Cave Diver program is designed to train divers in safe cave diving and if doing Technical cave the technical utilization of EANx for cave exploration, and the use of EANx and oxygen for decompression.

The final step in the process, the focus here is on gaining additional practice of all fundamental and emergency skills, under more challenging conditions. Students are expected to demonstrate their readiness to be full-fledged members of the cave diving community.

Between 12 to 16 training dives is required to reach this point, it is not unusual for students to have made many more practice dives on their own before full Cave Diver certification.


Equipment Requirements Open Circuit Cave diver

 1. IANTD Cave Diver Student Kit OR IANTD Technical Cave Diver Student Kit and NSS/CDS workbook.

2. All students must be taught the concept of gas matching.

3. All bottom mix tanks must be equipped with dual-outlet manifold valves. Independent cylinders may be used when configured as side mounts or back mounts for sump diving only.

5. An optional EANx stage cylinder containing a minimum of 50 cubic feet (1,400 free liters) of gas may be used for overhead penetration at the Instructor's discretion. 

6. Two (2) Primary regulators must provide ample gas flow. One second-stage hose must be at least 5 feet (1.5 meters) in length; longer hoses are recommended. 

7. Each gas source must have its own dedicated submersible pressure gauge.
