How to Choose the Right Speargun for Reef vs. Bluewater Hunting?

Spearfishing is one of the earliest fishing techniques that uses a handheld spear or harpoon to catch fish. Over time, technological advancements led to the invention of spear guns that are either elastic or pneumatic. Having the right speargun is crucial to getting the best spearfishing experience.   

Do you feel overwhelmed when selecting the right speargun from the array of options available in the market? Let our experts guide you in making an informed decision and choosing the right speargun for reef and bluewater hunting.

Fishing in coral reefs is entirely different from fishing in large oceans. You should choose the right speargun based on your skills, diving environment, target species, and your budget. So, how do you choose the best one for your needs? Let's break it down in simple terms.

Reef Spearguns: Maneuverability Matters

When you go for reef hunting, you need to choose spearguns that are shorter and more maneuverable than other Bluewater spearguns. In a reef, you have to navigate tight spaces, coral formations, and wrecks where fish dart quickly in and out of hiding spots. Because of this, reef spearguns are built for speed, precision, and ease of movement.

Speed and maneuverability matter as you fish in a rocky or coral reef environment. Fish like snapper, grouper, and hogfish are quick to disappear into crevices, so you need a speargun that allows fast reactions. A shorter barrel, typically between 70cm and 100cm, gives you the agility to track fish without getting stuck on coral or rocks.

Besides this, you will find smaller fish in the reef, which means you need a speargun that provides enough power to impale your target fish. A single or double-band speargun provides enough force for a clean shot at close range. More bands would only add unnecessary weight and slow down your reload time, which is crucial when hunting in fast-paced reef conditions.

Handle Placement: Mid vs. Rear Handle

Another key feature of reef spearguns is handle placement. Mid-handle designs offer better balance, making it easier to swing the gun quickly when a fish changes direction. Rear-handle spearguns are also common and can be more comfortable for beginners, but they may feel slightly less maneuverable in tight spaces.

The best reef spearguns are also quieter, reducing the chance of scaring fish away. Some models come with enclosed tracks or muzzle designs that minimize noise, giving you a better chance at a successful shot.

Bluewater Spearguns: Power and Range for Big Game

When you're hunting in an ocean (bluewater), you're targeting large, powerful fish like tuna, wahoo, and mahi-mahi—species that require serious stopping power.  You need to choose longer spearguns, usually between 120cm and 150cm or more. The extra length of the speargun facilitates accuracy and range, which is crucial when fish are swimming farther away. In open water, you may not get quite close to fish, hence a longer speargun will help you successfully target a fish swimming at a distance.

What's more, bluewater fish are stronger and faster, which means you need multiple power bands (usually three or more) to ensure the spear penetrates deeply enough. A single or double-band gun might not have the force required to secure a large tuna or wahoo, leading to lost fish and frustration.

Advanced Features for Big Game Hunting

Spearguns suitable for bluewater hunting come with specialized features to handle large, aggressive fish. Breakaway systems allow the spear to detach from the shooting line, preventing the fish from dragging your entire setup underwater. Slip tips are another critical feature—they pivot upon impact, increasing the chances of a secure hold.

Float lines are also essential in bluewater hunting. When you shoot a big fish, it can take off with tremendous force. A float line connected to a buoy helps absorb the shock, giving you a better chance of landing your catch without losing your gear.

How to Decide: Reef vs. Bluewater Spearguns

Now that you know the differences, how do you pick the right one? Here are a few key questions to ask yourself before making a decision.

Where Will You Hunt Most?

If you spend most of your time in shallow reefs, caves, or wrecks, a shorter reef speargun is the way to go. The compact design of the speargun helps you move quickly and avoid obstacles. On the other hand, if you're venturing into deep open water, a longer bluewater speargun will give you the range and power needed for bigger fish.

What Fish Are You Targeting?

Smaller reef fish like snapper or grouper don't require heavy firepower, so a 90 cm gun with one or two bands is sufficient. However, if you're after pelagic species like tuna or mahi-mahi, you'll need a 130 cm+ gun with multiple bands to ensure a clean, penetrating shot.

What's the Water Visibility Like?

In murky water or low visibility, a shorter speargun is easier to handle because you'll likely be taking shots at closer range. In clear blue water, where visibility can exceed 30 meters, a longer gun helps you take precise shots from a distance.

Additional Considerations before Buying

Testing Different Models

If possible, try out different spearguns before purchasing. Some divers prefer the feel of a wooden speargun, while others like the lightweight nature of carbon fiber or aluminum. Handling a few models will help you determine which one feels most comfortable in your hands.

Maintenance and Care

Saltwater is harsh on spearguns, so proper maintenance is crucial. Always rinse your gun with fresh water after each use to prevent corrosion. Regularly check the bands, shaft, and trigger mechanism for wear and tear. A well-maintained speargun will last much longer and perform better in the water.

Final Thoughts: Match Your Gun to Your Hunt

Choosing between reef spearguns and spearguns for bluewater comes down to your hunting style, target species, and environment. A well-selected speargun from a leading supplier like Neptonics improves accuracy, safety, and success rates—so take your time and pick wisely.

Whether you're weaving through coral reefs or chasing tuna in the deep blue, the right speargun makes all the difference. Get the best spearfishing experience and always remember to spearfish responsibly!
