Spearfishing Spearfishing Safety and Dive Planning 2

Question 1

What is 'samba' in the context of spearfishing safety?

Accepted Answer

Involuntary muscle twitching signaling impending blackout

Answer

Samba refers to the involuntary convulsive movement a diver experiences just before or during shallow water blackout, signaling a dive emergency.

Question 2

When planning a spearfishing dive near a river mouth or in variable current areas, what is the most important pre-dive check?

Accepted Answer

Tidal charts and current direction

Answer

Tidal charts and current data help divers avoid being swept away from their boat or entry point, which is a major safety risk.

Question 3

What does a spearfisher's dive float primarily serve as, beyond marking location?

Accepted Answer

A platform to rest on if fatigued, reducing drowning risk

Answer

A dive float gives the diver a surface rest point, reduces fatigue-related accidents, and supports the Diver Down flag.

Question 4

Which condition dramatically increases the risk of shallow water blackout?

Accepted Answer

Pushing to maximum depth on every dive

Answer

Repeatedly pushing to maximum depth stresses oxygen reserves and elevates blackout risk; divers should stay well within their comfortable limits.

Question 5

What is the proper first response if your spearfishing buddy goes limp underwater?

Accepted Answer

Immediately ascend them to the surface, supporting their airway

Answer

A blacked-out diver must be brought to the surface immediately to restore oxygen supply; delay causes brain injury or death.
