Spearfishing Equipment 3 — Questions and Answers
Question 1: What material are most modern spear shafts made from?
- Aluminum
- Hardened spring stainless steel (Correct answer)
- Carbon fiber
- Titanium alloy
Correct answer: Hardened spring stainless steel
Hardened spring stainless steel resists bending and corrosion while staying strong.
Question 2: What is the benefit of a low-volume freediving mask?
- Wider field of view
- Easier equalization at depth and less buoyancy (Correct answer)
- Built-in defogging
- Stronger lens glass
Correct answer: Easier equalization at depth and less buoyancy
Low internal air volume is easier to equalize at depth and creates less drag and buoyancy.
Question 3: Which weighting system is most commonly used by spearfishers?
- Integrated BCD weights
- A weight belt or weight vest (Correct answer)
- Ankle weights only
- Lead-lined fins
Correct answer: A weight belt or weight vest
A rubber weight belt or weight vest offsets wetsuit buoyancy and is quick to ditch in emergencies.
Question 4: Why should a weight belt use a quick-release buckle?
- To adjust fit during the dive
- To drop weights fast and ascend in an emergency (Correct answer)
- To attach extra weights easily
- To hold the knife
Correct answer: To drop weights fast and ascend in an emergency
A quick-release lets a diver ditch the belt instantly to gain buoyancy and surface in trouble.
Question 5: What is a pole spear (Hawaiian sling pole) typically used for?
- Long-range open ocean hunting
- Close-range hunting of reef fish (Correct answer)
- Deep wreck penetration
- Night drift fishing only
Correct answer: Close-range hunting of reef fish
A pole spear is a short, band-powered shaft ideal for close-range reef and small fish hunting.
Question 6: What does a slip-tip (breakaway tip) do when it hits a large fish?
- Snaps off and is lost
- Toggles sideways inside the fish to prevent tearing out (Correct answer)
- Releases a dye marker
- Folds back into the shaft
Correct answer: Toggles sideways inside the fish to prevent tearing out
A slip-tip detaches and toggles inside the fish, holding securely so it cannot pull free.
Question 7: Why do spearfishing gloves often have reinforced palms?
- For better grip and protection when handling fish and rocks (Correct answer)
- To add buoyancy
- To improve insulation only
- To hold the speargun trigger
Correct answer: For better grip and protection when handling fish and rocks
Reinforced palms protect hands from spines, rocks, and abrasion while improving grip.
