IANTD Full Cave Diver

Prerequisites
Divers interested in the IANTD Full Cave Diver Course must be Intro to Cave certified, 18 years of age, and have a minimum of 50 logged dives.

Performance Requirements:

Minimum 400 minutes of bottom time

8 to 12 dives completed

Minimum of 3 different caves

Land Drills:

Use of lines/line arrows

Blacked out drills

Lost diver drills/broken lines/line gaps

A confined water dive must be conducted:

Swim with equipment to be used in program until comfortable with it

Divers using a quick release on their harness or backpack must in confined water; swim the system while the instructor disconnects the quick release to simulate a failure. The student is to swim the system demonstrating control of buoyancy and body positioning with the quick release disconnected for sufficient duration to satisfy the instructor that the student is capable of managing this type of failure.

Demonstrate the ability to respond to a single bladder BCD failure by the two methods.

Completely deflate BCD and swim while maintaining buoyancy control for at least two minutes.

Completely deflate BCD, ascend safely to the surface, and remain afloat for at least three minutes

Swim 60 feet while simulating an out of gas situation, then commence gas sharing via the long hose, remain at rest for three breaths and swim of 10 minutes at a normal swim rate of approximately 75 feet a minute.

Two divers 50 feet apart must swim along a line circuit with eyes closed not taking a breath, while slowly exhaling until they meet. Upon meeting, gas sharing via the long hose combined with touch contact is to be performed until the line circuit is completed.

Perform a pre-dive ‘S’ drill prior to starting dive. Check all equipment for proper function. Check equipment of each dive buddy. Ascertain each team member is familiar with use and location of dive system components.

Perform an ‘S’ drill prior to every dive

Communicate the gas turn around point in psig, and if the divers are wearing different cylinder sizes, match gas per SRF tables or per dissimilar tank volumes.

Demonstrated proficiency in propulsion techniques taught in previous courses.

Practice use of reels and lines.

During a cave dive, at a point after turning the dive, perform a gas sharing drill exiting the cave for a reasonable distance/time. Exercise is to commence with Instructor at some point randomly selecting the out of gas diver, who must then go to the buddy and share gas. The out of gas diver is to keep the regulator in his or her mouth (leaving the airway open) but not breathe from it if at all possible. This drill is to be repeated on different dives until all students have been both a donor and a recipient of gas.

On a cave dive, exit cave with eyes closed or lights off maintaining contact with buddy and dive line using touch communications.

Repeat previous drill,, except at some point the Instructor will choose one of the divers to simulate being out of gas. The out of gas diver must communicate the problem to a buddy via tough contact, and gas sharing is to be performed for a reasonable distance. Repeat this skill until all students have been both a donor and recipient of gas.

Perform lost diver drills

Perform lost line drills

Demonstrate either on a cave dive or confined water the ability to drop and recover a stage cylinder. This may be the tank used as a decompression tank or an actual penetration stage cylinder.

Conduct a traverse, gap and circuit dive.

On at least three dives, the student must simulate a regulator failure and while swimming shut off the valve for the primary regulator and switch to a secondary regulator. Upon completion, the diver is to turn on the valve for the primary regulator and switch back to it. A buddy should act as a safety diver during this drill

On at least three occasions, an out of gas drill must be completed with the donor being aware of whether it is a drill or a real out of gas situation
