Speargun Building Essentials: Everything You Need at Diversworld

1. Speargun Barrels: Aluminium vs. Carbon

One of the first decisions you’ll need to make is choosing the right barrel for your speargun. At Diversworld, we offer both aluminium and carbon barrels, each with its own benefits.

• Aluminium Barrels: Known for their durability and affordability, aluminium barrels are perfect for spearos looking for a reliable and sturdy option. Aluminium can withstand rough underwater environments and is an excellent choice for beginner builders or those on a budget.

• Carbon Barrels: If you’re looking for superior performance and reduced weight, carbon speargun barrels are the way to go. Carbon barrels are lighter and offer better maneuverability underwater, making them ideal for advanced spearos targeting faster or more elusive fish. They also resist corrosion, ensuring longevity in saltwater environments.

2. Constrictor Knot Cord

A constrictor knot cord is essential for securing the bands on your speargun. This high-strength cord ensures that your bands are tightly fastened, which is crucial for both accuracy and power when shooting. At Diversworld, we offer a variety of constrictor knot cords that are tough, durable, and easy to work with.

3. Roller Heads and Roller Gun Bridles

Roller spearguns are becoming increasingly popular thanks to their efficiency and power. To convert your speargun into a roller setup, you’ll need roller heads and roller gun bridles.

• Roller Heads: These heads allow the speargun to utilize the entire length of the barrel, providing a longer power stroke for each shot. This results in more power and speed without the need for additional bands.

• Roller Gun Bridles: Roller gun bridles are used to anchor the bands and transfer power to the shaft. They are essential for creating a smooth, frictionless loading experience and are designed for easy installation and maximum durability.

4. Mono and Dyneema Reel Line

Spearfishing requires a robust line that can withstand high tension, especially when you’re pulling in big fish. At Diversworld, we offer two popular options for your speargun’s reel line: Mono and Dyneema.

• Mono: Monofilament line is an affordable, strong, and abrasion-resistant option that’s perfect for spearfishing. Mono is ideal for clear water conditions and is known for its low stretch, giving you excellent control when spearing.

• Dyneema Reel Line: Dyneema is considered one of the strongest materials available, offering exceptional strength and resistance to abrasion. Dyneema is especially useful for large pelagic fish, where you need a line that can handle extreme conditions without snapping.

5. Shark Clips

Shark clips are essential accessories for attaching various components of your speargun rig, such as lines, floats, or reels. At Diversworld, we stock high-quality shark clips designed to be corrosion-resistant and easy to operate with one hand—ideal for fast, efficient rigging underwater.

6. Neptonics Push Rod

The Neptonics Push Rod is a must-have for speargun builders using roller setups. This push rod helps facilitate smooth band engagement and enhances the overall loading experience. Designed for durability and reliability, the Neptonics Push Rod is the perfect accessory for speargun builders looking for high-performance components.

7. Reels and Rubber

Finally, a custom speargun wouldn’t be complete without the right reel and rubber. At Diversworld, we carry a wide selection of reels, from entry-level models to advanced options designed for large fish. Our selection of speargun rubbers also ensures that you can fine-tune your speargun’s power to match your specific hunting style.
