PADI Search & Recovery Diving

Question 1

Which PADI search pattern uses a fixed pivot point on the bottom and has a surface tender extend the line to sweep progressively larger arcs?

Accepted Answer

Circular/arc search

Answer

The circular/arc search uses a line attached to a fixed pivot point, allowing the diver to sweep arcs of increasing radius as the tender pays out line.

Question 2

What is the primary advantage of a jackstay search pattern compared to other search methods?

Accepted Answer

It provides systematic, complete coverage of a defined area

Answer

The jackstay pattern uses parallel reference lines to ensure every part of the search area is covered systematically, minimizing gaps.

Question 3

When planning a search and recovery dive, what should be established FIRST before entering the water?

Accepted Answer

A clear picture of what is lost, its approximate size, and last known location

Answer

Gathering information about what was lost, its characteristics, and last known position allows the team to select the most appropriate search pattern and equipment.

Question 4

What is the MOST important safety rule when using a lift bag for underwater recovery?

Accepted Answer

Never exceed the lift bag's rated lifting capacity

Answer

Exceeding a lift bag's rated capacity can cause an uncontrolled rapid ascent, endangering divers and potentially losing the recovered object.

Question 5

Which knot is most recommended in PADI Search and Recovery for creating a secure, non-slipping loop to attach lines to recovered objects?

Accepted Answer

Bowline

Answer

The bowline creates a fixed, secure loop that does not slip under load and can still be untied after stress, making it ideal for rigging in S&R.
