PADI Wreck & Cave Diving Fundamentals 3

Question 1

In cave diving, what is a 'jump' or 'jump connection'?

Accepted Answer

A technique to cross from one guideline to another at a T or junction

Answer

A jump allows a diver to leave one guideline and connect to another at a junction using a jump reel to maintain a continuous line.

Question 2

What is the recommended minimum number of lights a cave diver should carry?

Accepted Answer

One primary and two backups

Answer

Cave divers carry three lights — one primary and two backups — because total darkness renders the dive immediately life-threatening.

Question 3

Which hazard unique to wreck diving can cause a diver to become positively buoyant unexpectedly?

Accepted Answer

Air pockets trapped in inverted compartments

Answer

Air pockets trapped in inverted hull sections can cause unexpected buoyancy shifts if a diver enters or exits them.

Question 4

What is the significance of a 'line arrow' (permanent arrow) placed on a cave guideline?

Accepted Answer

It indicates the direction toward the closest exit

Answer

Permanent arrows always point toward the nearest exit, helping disoriented divers find their way out quickly.

Question 5

Which diving condition is most likely to cause rapid loss of guideline visibility in a wreck or cave?

Accepted Answer

Fine silt disturbed by exhaust bubbles or fin kicks

Answer

Fine silt particles are easily suspended by exhaust bubbles or poor fin technique, causing rapid and complete visibility loss.
