How to Inspect and Service Your Speargun Trigger (Step-by-Step)

A smooth trigger makes every dive safer. It also boosts accuracy. Many spearfishers forget this critical task. However, frequent inspections ensure your equipment is secure and that water output is enhanced. Through this informative post, you will learn how to service and inspect your speargun trigger step by step.

The Importance of Trigger Maintenance

A trigger is the heart of your speargun. It holds the shaft under tension. It also releases it with precision. A small problem can become a big risk. Rust, sand, and salt weaken trigger parts fast. Therefore, routine care is essential. When you understand the mechanism, you dive with more confidence.

Tools You Need

Before starting, gather a few simple tools.

• A screwdriver

• A soft brush

• A microfiber cloth

• Marine-grade grease

• Fresh water

• A small flashlight

You are ready to start with these things. All the steps given below are easy and non-hazardous.

Step 1: Rinse the Complete Entire Speargun

To begin with, sponge your spear gun in fresh water. Salt builds up quickly. Sand gets into small spaces. Proper rinsing helps prevent permanent injury. Maintenance: Run water over the handle and trigger. Gently shake the gun to get loose debris. This is followed by preparing the weapon for further cleaning.

Step 2: Take out the Trigger Mechanism

Then remove the trigger from the speargun. The majority of models have two or three screws. Store the screws somewhere safe. Use a container to ensure nothing is lost. Caution is necessary, as some internal parts will slide around. However, you will have an easy time working at a pace.

Step 3: Check On each Trigger Part

Now inspect the mechanism closely. Look for rust, cracks, or bending. Use a flashlight for better visibility. Also, check the seal, housing, and safety. Gently move each part. Everything should move smoothly. If something feels stiff, you will fix it in the following steps.

Step 4: Clean the Trigger Housing

After inspection, start cleaning. Use a soft brush to remove sand. Brush lightly around the sear and pivot points. Never scratch the metal. Then wipe everything with a microfiber cloth. Make sure you remove all moisture. Moisture leads to rust. That is why this step matters.

Step 5: Lubricate with Marine-Grade Grease

Once the parts are clean, apply a thin layer of grease. Use only marine-grade grease. Regular grease washes off too fast. Start with the pivot pins. Then add a small amount to the seal contact points. Do not use too much. Extra grease catches sand. A small amount keeps the trigger smooth and safe.

Step 6: Reassemble the Trigger Mechanism

Following lubrication, reassemble the trigger mechanism. Put in each piece. Adjust the speargun to the housing. Fit the screws, but do not over-tighten. Once all is safe, check the trigger movement without any shaft loaded. It should feel crisp. It should also reset cleanly after each pull.

Step 7: Test the Trigger Before Your Dive

Testing is the final step. You must confirm everything works. Pull the trigger several times while holding the gun safely. Engage and disengage the safety. If the movement feels rough, repeat lubrication. If the parts feel loose, recheck the screws. A few extra minutes now prevent problems underwater.

How Often Should You Service Your Trigger?

You should service your trigger every few months. But if you dive often, do it more frequently. After shore dives, rinse the mechanism immediately. Sand-heavy spots require extra care. If your dives involve deep water or big fish, stay consistent. A well-maintained trigger improves accuracy and safety on every trip.

Signs Your Trigger Needs Immediate Attention

You must inspect your speargun right away if you notice:

• A rough or sticky pull

• Rust forming on metal parts

• Difficulty engaging the safety

• A loose trigger housing

• Any odd clicking or grinding

These signs warn you early. Quick attention prevents misfires. Always listen to your gear.

Upgrading Your Trigger for Better Performance

Many divers upgrade their trigger mechanism for smoother shots. A stronger mech improves handling. A stainless-steel internal design lasts longer. If you dive in heavy conditions, consider an upgrade. High-quality triggers reduce friction. They also support thicker bands and higher load strength. Choosing a reliable brand matters most.

Trigger maintenance is simple. However, it is among the most significant sections of speargun maintenance. Your speargun will be in good condition with regular cleaning, lubrication, and checks. Every diver should build this habit. You will shoot more accurately. You will also dive more safely.
