Whether you’re a seasoned spearo or a beginner looking to improve, having a finely tuned speargun makes all the difference. Upgrades can help you achieve:
- Increased accuracy: Better band alignment and trigger consistency lead to more precise shots.
- Greater power: A well-rigged speargun can extend your range and penetration capabilities.
- Enhanced reliability: High-quality components reduce the risk of breakdowns, so you can focus on the hunt.
If you want to take your spearfishing to the next level, these top upgrades will help you maximize performance and durability.
Upgrade #1: Strengthen Your Reel Line
Upgrading your reel line is a quick win for boosting reliability. A line that’s tough enough to handle big fish yet smooth enough to minimize friction is essential.
Why Dyneema Reel Line?
Dyneema reel line is celebrated for its extreme tensile strength and abrasion resistance. It stays strong under stress, making it perfect for handling larger catches and rough underwater conditions.
Benefits
- High break strength: Fewer break-offs when fighting fish.
- Low stretch: Better sensitivity and accuracy.
- Durable: Long-lasting performance, even in harsh saltwater environments.
Pro Tip: Pair Dyneema reel line with copper crimps for secure, reliable rigging. Copper crimps are easy to install and help ensure there are no weak points in your line.
Upgrade #2: Enhance Power & Band Placement
Power bands and their supporting components can make or break your speargun’s performance. By fine-tuning band placement, you’ll achieve higher velocity with each shot.
Power Band Elevators
Power band elevators help correctly align your bands so they deliver optimum thrust. By elevating the bands slightly, you reduce drag and enhance the gun’s power transfer.
Roller Gun Bridle & Wishbone Bridle
- Roller gun bridle: Roller setups effectively multiply the band’s power, giving you a higher shot velocity without needing more or heavier bands.
- Wishbone bridle: This simpler bridle style is easy to maintain and ensures consistent tension for standard speargun configurations.
Constrictor Knot Cord
Don’t forget to use constrictor knot cord when tying off your new bands or bridles. Its secure grip and minimal slippage are key to safe, reliable band setup.
Pro Tip: Always check your knots before each dive. A loose knot can result in misfires or lost fish!
Upgrade #3: Optimize Trigger & Release Mechanisms
A smooth, predictable trigger pull can drastically improve your accuracy—and safety. Consider upgrading the core mechanisms inside your speargun.
Neptonics Heinrich Release
The Neptonics Heinrich Release offers a cleaner line release. This means fewer tangles and a more consistent shot, especially if you use a reel line or float line system.
Push Rod
A high-quality push rod ensures a seamless connection between the trigger and the release mechanism. This reduces friction and the chance of accidental discharge, giving you peace of mind on every dive.
Installation Jigs for Trigger Mechanisms
Upgrading your trigger or installing a new release mechanism can be daunting. Installation jigs make it simpler to line up components correctly, ensuring a professional fit—no guesswork required.
Pro Tip: Always follow the manufacturer’s instructions or consult a professional if you’re unsure about installing trigger components yourself.
Upgrade #4: Improve Safety & Comfort
Spearfishing should be as safe and comfortable as possible. Here are a few must-haves:
Rob Allen Loading Pad
A bruised chest is one of the biggest complaints among spearos. A Rob Allen loading pad provides cushioning and grip, making it easier (and less painful) to load your gun repeatedly.
Rear Shaft Cap for Sten
If you use a pneumatic speargun like the Sten, a rear shaft cap offers extra protection by preventing accidental shaft ejection. It’s a small but critical safety feature.
Pro Tip: Regularly inspect your speargun for wear and tear. Replacing small parts can extend its life and keep you safer in the water.
Bonus Tip: Essential Replacement Parts & Accessories
Stocking up on spare parts prevents downtime if something fails. A few extras to consider:
- Mare Line Retainer for Cyrano Gun: Keeps your shooting line organized.
- Copper Crimps: Essential for secure line rigging, as mentioned above.
- O-Rings & Seals (not listed but always good to have): Preserve pneumatic gun pressure.
Having backups on hand means you can quickly fix an issue and get back in the water.
Final Thoughts
Upgrading your speargun isn’t just about adding gadgets—it’s about ensuring every shot counts, every dive is safer, and every hunt is more enjoyable. From Dyneema reel line and roller gun bridles to Rob Allen loading pads and trigger mechanism jigs, these strategic enhancements can transform your spearfishing experience.
