Polespear

A typical polespear used in spearfishing.

A polespear is a type of underwater fishing tool used primarily in spearfishing. It is a simple, yet effective device that allows divers to catch fish by thrusting the spear at the target. Polespears are popular among both recreational and professional spearfishers due to their ease of use and effectiveness in various underwater environments.

Design and Construction

A polespear typically consists of a long shaft, usually made from materials such as fiberglass, carbon fiber, or aluminum. The shaft is designed to be lightweight yet strong enough to withstand the forces encountered during spearfishing. At one end of the polespear, there is a sharp tip, often equipped with barbs to secure the catch. The other end of the polespear is fitted with a rubber sling or band, which provides the propulsion needed to launch the spear towards the target.

Shaft

The shaft of a polespear can vary in length, typically ranging from 4 to 10 feet. The choice of length depends on the type of fish being targeted and the environment in which the spearfishing takes place. Longer polespears offer greater reach, while shorter ones provide better maneuverability in tight spaces such as coral reefs or kelp forests.

Tip

The tip of a polespear is crucial for ensuring a successful catch. Common types of tips include:

• Paralyzer tip: Features multiple prongs that spread upon impact, increasing the chance of hitting the target.
• Single barb tip: A single sharp point with a barb to prevent the fish from slipping off.
• Slip tip: A detachable tip that remains in the fish, allowing the shaft to be retrieved easily.

Sling

The rubber sling or band is attached to the rear end of the polespear. To use the polespear, the diver stretches the sling along the shaft, holding it in place with one hand while aiming. Upon release, the stored energy in the stretched sling propels the spear forward with significant force.

Usage

Polespears are used by divers who prefer a more traditional and challenging method of spearfishing. The diver must get close to the fish, requiring skill and stealth. Polespears are particularly effective in shallow waters and are often used for hunting smaller fish species.

Techniques

Successful use of a polespear involves several techniques:

• Stalking: Approaching the fish quietly and slowly to avoid startling it.
• Aiming: Aligning the spear with the target, taking into account the refraction of light in water.
• Thrusting: Releasing the sling and thrusting the spear forward with precision.

Advantages and Limitations

Polespears offer several advantages:

• Simplicity: Easy to use and maintain, with few moving parts.
• Portability: Lightweight and easy to transport.
• Stealth: Quiet operation, minimizing disturbance to the underwater environment.

However, polespears also have limitations:

• Range: Limited range compared to other spearfishing tools like spearguns.
• Power: Less powerful, making it challenging to catch larger fish.
