Speargun Parts You Should Always Carry on a Dive: The Survival Kit

Spearfishing demands preparation. Every dive brings new challenges. Gear fails. Conditions shift. Small parts break at the worst time. Yet you can avoid most problems with an innovative speargun survival kit. You only need a few essential parts. These parts keep your gun working. They also keep your dive safe and productive.

In this guide, you will learn the most essential speargun parts to carry on every trip. These parts weigh almost nothing. However, they can save your entire session. Let’s explore them one by one.

1. Extra Bands

Bands lose tension. Sunlight weakens them. Sharp fish scales can cut them. Therefore, always carry an extra band or two. Pre-tied bands save time. You can swap them fast. Strong bands also improve accuracy. So pack high-quality rubber that matches your gun. This simple part can rescue a ruined dive.

2. Spare Shafts

Shafts bend. Rocks eat tips. Big fish can damage shot alignment. Because of this, a spare shaft is essential. Many divers keep one clipped to their float. You can switch it in seconds. With a second shaft, you stay ready for big fish all day. It also boosts confidence because you know you have a backup.

3. Extra Shooting Line

Shooting line frays. Coral shreds it fast. One hard fight can ruin your rigging. Thus, carry extra mono, Dyneema, or coated cable. Pre-crimp it at home if possible. When the line snaps, you can rebuild fast. Your survival kit should also include crimps, cutters, and pliers. Being able to fix your line quickly keeps your dive smooth.

4. Replacement Wishbones

Wishbones fail often. Sand gets inside. Rust builds. Rubber cracks. Although they are small, they matter. A broken wishbone ends the action. So keep a couple in your kit. They weigh almost nothing. With a few spares, you avoid downtime and keep your shot accurate.

5. Extra Trigger Components

Some divers overlook this. But trigger parts wear out. Springs pop out. Pins loosen. Because triggers keep you safe, stay ready with extra pins and a spare safety spring. These small parts protect your entire day. You may never need them. Still, when you do, you will thank yourself for carrying them.

6. Tip Adapters and Slip Tips

Slip tips give you better holding power. Yet they can break or jam. Rocks can damage adapters. Therefore, keep a spare adapter and tip. This lets you change your setup fast. It also helps when you target different fish in one day. A quick swap keeps you ready for anything underwater.

7. O-Rings and Shock Absorbers

Shock absorbers take impact. O-rings seal pressure points. Over time, both wear out. They may crack at depth. Always pack fresh O-rings. Also pack a spare shock bungee. These tiny parts protect your spear, line, and accuracy. They also reduce gear stress. A simple replacement can instantly improve your day.

8. Small Tool Kit

You need tools to fix anything. Your kit should include:

• Mini screwdriver

• Allen keys

• Crimping tool

• Small pliers

• Sharp line cutters

These tools solve almost every problem underwater. They also help with emergency rigging. With them, you can maintain your gun anywhere.

9. Reel Line and Reel Components

Reels jam. Line twists. Fish can strip your spool. For this reason, carry an extra reel line. Also have a spare reel screw and knob. These tiny failures can ruin a hunt. But with backup parts, you recover fast. Always check your reel before each dive.

10. Floatline Plugs and Clips

Floatlines drag on reefs. Rocks tear plugs. Fish twist swivels until they snap. So include spare plugs and stainless clips. They help you rebuild quickly. A floatline failure risks losing your shaft, your gun, or your fish. Backup plugs prevent that.

Building Your Personal Kit

• Extra band

• Shaft

• Line

• Crimps

• Wishbones

• Tools

Organize these parts in a dry-proof pouch. Label the pockets. Keep the kit in your dive bag. With a set routine, you avoid gear mistakes. You also reduce stress before the dive.
