Question 1

What is the maximum depth limit for PADI Open Water certified divers?

Accepted Answer

30 meters (100 feet)

Answer

PADI Open Water certified divers are certified to a maximum depth of 18 meters (60 feet), though the recreational limit is 40 meters with advanced training.

Question 2

Which hand signal indicates 'I am out of air' underwater?

Accepted Answer

Flat hand slashing across throat

Answer

The flat hand slashing across the throat is the universal signal for 'out of air,' prompting your buddy to share air.

Question 3

What happens to a diver's buoyancy as they descend deeper?

Accepted Answer

Buoyancy decreases as the wetsuit compresses

Answer

As depth increases, water pressure compresses the neoprene in a wetsuit, reducing its volume and making the diver less buoyant.

Question 4

What is the primary purpose of a surface marker buoy (SMB)?

Accepted Answer

To signal your location to boats while ascending

Answer

An SMB is deployed during ascent to signal divers' positions to surface vessels, greatly reducing the risk of boat strikes.

Question 5

A diver notices their pressure gauge reads 500 psi (35 bar). What should they do?

Accepted Answer

Signal their buddy and begin a safe ascent

Answer

500 psi is typically the reserve pressure; divers should signal their buddy and begin ascending together while air remains for a controlled ascent.
