How to Pick the Right Speargun Length For You

There is no simple answer for the right speargun length you need. There are several factors that you will need to answer for the type of diving you are doing. By answering these questions you can narrow down the right length speargun you will need for the diving you will be doing. Here are some of the important considerations when picking your speargun length. 


The biggest factor in picking your speargun should be normal visibility in your dive location. Visibility is so important because it will impact fish behavior dramatically. The further away the fish can see a diver the longer the shot that diver may have to take. That means in clean water you will likely need a longer speargun to get the longer ranges. The opposite side of the spectrum is still an important to consider. In bad visibility you will want a short, maneuverable speargun to get the spear pointed at the fish quickly. Even in bad visibility it is important to be able to see the end of your speargun, the fish, and what is beyond the fish. Make sure you are practicing safe spearfishing and always know what is beyond your target. 


After normal visibility conditions you need to consider the speargun’s maneuverability. Other than the physical designs of the speargun, the length is going to impact how well the speargun tracks through the water. If you are hunting reef fish that dart into hole, ledges, or caves that could mean the right length speargun for you is going to be a short gun. You may not need to take a long shot, but you will need to get your speargun pointed at a fish in a hole quickly before it hides even deeper in the rocks. Pelagic species, that stay in the water column, may give you a longer opportunity to get the speargun pointed at the fish, so maneuverability may be less important. 

The Right Speargun Length for the Fish You Are Targeting

The last big consideration comes down to the type of fish you are targeting. Some species just stay far away from divers. So you need a long, powerful speargun to get the range needed to hunt them. Wahoo, Tuna, and Billfish are all great examples of fish that usually require longer shots. There are always stories about divers who were lucky enough to get point blank shots, but overall these fish keep their distance. That means long, bulk spearguns with four to six bands. That size gun loses maneuverability, and really can’t be used in limited visibility, but it is a specialized speargun for a specific purpose. Most reef species don’t need as much speargun, but it can come down to your hunting technique as well. 

Picking the Right Speargun Length – What it All Means To You

You should get a speargun that has a similar effective range to the visibility where you dive. The effective range of a speargun is generally, about two to three times the length of the speargun’s band stretch distance. Notable exceptions come into play if you are targeting reef species in holes. Then you just want a speargun that has enough power to put the spear shaft through the fish. The challenge of picking the right speargun comes down to the problem that there is no single speargun that meets all of a diver’s needs. As time goes by you will collect all the spearguns you need for the types of diving you do.

Spearfishing Terminology – A Clarification of Terms

Over the years we have had the pleasure of interacting with hundreds, if not thousands, of new divers getting into spearfishing. One of the biggest hurtles new divers have when they are getting into the sport is the spearfishing terminology that are used within diving. With the combination of slang and technical terms that may vary from similar objects in other industries, spearfishing equipment can get confusing. Additionally, the diverse groups of people that spearfish can bring with it translation miscommunications. We hope to put, in plane terms, some of the miscommunications we have heard, and create some standardization in what we mean when we use certain terms. 


Spearfishing is the act of harvesting fish while in or under the water, using any tool to penetrate a fish and secure it. This can be done with spearguns, pole spears, and Hawaiian slings. There have been several terms that new divers have used over the years. There is no shame in not knowing the right words to a new activity. Some of the more common phrases we have encountered are “spear diving” and “underwater fishing”. They are in their own way accurate descriptions of the activity, but the preferred term is “spearfishing”.

Speargun Terms

While we have seen some interesting terms for spearfishing over the years, it does not compare to the wide range of terms we have seen for spearguns. Probably the most interesting we have come across is the result of rough translations. The common Latin American term for a speargun translates roughly to “underwater shotgun” in most variations of Spanish. Other common searches come to some type of “underwater harpoon gun”. People also frequently come looking for “fishing guns”, “spearfishing guns”, or “spearfishing guns”. Many divers think of a speargun as an “underwater crossbow”, and new divers have described it that way as well. These are all spearfishing terms that are close enough that you can effectively communicate to someone in the dive industry, but the term “speargun” still is the best.

Pole Spear and Hawaiian Sling

Pole Spears are normally called multiple things within the diving industry anyway. Probably the most common mix up is calling pole spears Hawaiian slings, which is another type of spearfishing tool. Other common terms are “three prong” which refers to a pole spear with a specific type of tip on the end. Most modern high quality pole spears have resorted to using a slip tip rather than a three prong. Other divers refer to both Pole Spears and Hawaiian Slings collectively as “slings” or even “sling spears”. Some of the harder terms people have used to describe pole spears have been “hand spear” and “spear fishing pole”. While some dive shops may understand what you mean it is still best to be specific with the tools you are asking about. 

Terms for Spear Shafts

Spear shafts are an integral part of using a speargun. Within the industry there are a couple trees that are easily recognized as a spear shaft. Think of it like the term “soda-pop”. Some spearfishing terminology people use for spears, some people call it a shaft, other say spear shaft all together. All three are acceptable terms. As a company that ships things globally, we find shaft to more accepted by most country’s customs and boarder police from an importing without questions stand point. Some of the terms we have run into with some people are “spearfishing spear”, which usually get them close. Then we run into people that compare the spear shaft to similar objects in other industries. “Bolt” or “arrow” is common from people more familiar with archery and crossbows. “Harpoon” is a common mistake due to translation as well as from a comparison to a different tool.


There are a wide range of wetsuits available in the dive industry. Freediving and spearfishing wetsuits tend to be open cell wetsuits with camouflage patterns on the outside of the neoprene. They come in different thicknesses for different water temperatures. Some of the terms we run into that are a little off from the normal freediving or spearfishing wetsuit term include “spear diving wetsuit”, “dive suit” or “spearo wetsuit”. Spearo has become a slang word that has gained some acceptance in the spearfishing community. We occasionally run into someone that insists they want, or have bought, a “drysuit” from us. Drysuits do exist. They are used by scuba divers in extremely cold water, or cool water for extremely long exposures. Freedivers don’t use drysuits. Wetsuits work by trapping a thin layer of water between the diver and their wetsuit. Their body heat warms that water and insulates the diver. 


Speargun Basics – What You Need To Know

If you are just getting into spearfishing you may have a few questions about spearguns and how they work. Fortunately, they are no overly complicated tools. There will be variations in different manufacturers designs, but the basic construction is pretty similar. We will cover some speargun basics and go over some of the common questions we get from people just getting into spearfishing.

What is a Speargun?

A speargun is any tube shaped item that holds a spear shaft which is propelled by stored energy that is released with some type of trigger mechanism for use underwater. That stored energy can be from pulling back bands that connect to the spear shaft through notches bin the spear shaft. The energy can also be stored through pushing a spear shaft through a pneumatic tube into a trigger mechanism. They work by storing this energy safely and by being able to release the spear shaft to be shot at a fish at the right time. 

Are Spearguns Illegal? 

Every country has their own laws. Within some countries different regions may have even more specific restrictions. The short answer is that you need to check in your area to find out if spearguns are legal. Most states in the United States are open to spearfishing. The Bahamas and Bermuda have outlawed them, but allow pole spears and Hawaiian slings. 

Is a Speargun a Firearm?

No! Spearguns are powered by latex rubber bands or pressurized air. Firearms are powered by an explosion of a propellent that causes large amounts of pressure in a restricted space facing a small projectile through a narrow space. Don’t go through your local airport shouting that you have a speargun. The general public is not overly aware of the differences. So while traveling it may be best to refer to your gear as “fishing equipment”, unless you feel like filling out a lot of paperwork and getting some interesting questions from security and the airline. Many people ask about a spear rifle. This is a confused term. Rifles are firearms with a rifled barrel designed to spin the bullet as it passes through a barrel to increase accuracy at range. The short ranges of spearguns makes rifling is unnecessary.

Can You Use One Out Of The Water?

No! Can you physically load a speargun and fire it out of the water? You can if you are an idiot. Spearguns are designed to be used in an environment with water resistance. That water resistance helps with recoil and reduces the range of the spear shaft. That water resistance also helps by increasing the spear shaft’s accuracy. DO NOT FIRE SPEARGUNS OUT OF THE WATER. For more information on speargun safety please read this blog post. 

What is The Best All Around Length?

There is no perfect length for all diving everything. It is a continuous effort that many builders have been trying to create from the beginning. There are good general lengths that cover most diving. As you get further into spearfishing you will find that the right tool for the job makes a big difference. You will end up collecting quite a few as time goes by. For more information on picking the right gun length for your diving check out this post as a speargun length guide. 

What is The Difference Between a Speargun and a Harpoon Gun?

We already went over what a speargun is earlier. You mount Harpoon Guns to the deck of a boat. It fires a harpoon in order to retrieve large fish, like Tunas and Billfish. Some of the biggest differences are that harpoon guns are used from out of the water shoot into the water. You shoot spearguns in the water at fish that are also in the water.


There are a wide range of prices on the market. You get what you pay for with spearguns. There are plenty of inexpensive ones on the market, but make sure you you are getting a quality gun for the price. A cheap speargun may end up costing you more long term that the right purchase from the start. The cost of regular repair and maintenance can quickly get you ‘cheap’ speargun over the price of a quality Rob Allen or Amero very quickly. Most spearguns will cost between $260 up to well over $1000 depending on the type and quality you are looking for. There are even some spearguns on the market for well over $3000.

What is a Speargun’s Range?

Band stretch distance determines range. Most will shoot between two to three times the distance from the back of the band slot to the notch where the bands connect to the spear shaft. Roller guns are the exception to this rule, because the starting point of the bands is different. For more information check out this post on how roller spearguns work. Range is important for some spearfishing, but it shouldn’t b e the only thing you look for in your speargun. That means you need enough power to send the spear shaft through the fish. You also have to make sure you don’t overpower your speargun. Overpowering the speargun will c use major inaccuracy in your shots.

Riffe Speargun Series – A Look at Riffe Speargun Models

Riffe has been on the forefront of spearfishing since the 1970s. With decades of consistently creating quality spearfishing equipment it only makes sense that their spearguns are held in high regard. We will be taking a look at some of their more popular models of today.

Riffe Euro

The Riffe Euro Speargun is easily one of the best freediving wooden spearguns on the market. The Euro is streamline and easy to track through the water. This speargun is powered by two 5/8” (16mm) power bands that can be easily taken on or off the speargun. This wooden speargun has the power to make accurate shots at a great range. Riffe has set the trigger for this speargun near the back of the speargun to allow for maximum power for the length of the speargun. The rear handle design ensures easy point and shoot capability. Overall, this wooden speargun is hard to beat, with many models coming in both open and enclosed track options. 

The Competitor

The Riffe Competitor Speargun series is a classic. This particular design has been around, in some form, for around 20 years. The reason it has been around so long is simple: it works! With a narrow design it is easy to see and track your fish as you are looking down the speargun. This speargun is easily hip loaded, as the trigger is located further forward on the stock. With a traditional band slot it is easy to install pre-made power bands on this mahogany wooden speargun. 

Riffe Marauder

The Riffe Marauder Speargun is a great design for some bluewater spearfishing. The laminated mahogany stock helps prevent warping. The cuttlefish body design adds mass, while still allowing the speargun to track easily through the water. The added mass reduces recoil, allowing for more power on the speargun. The added power translates to more penetration through fish from further away. This makes the Riffe Marauder a tempting option. Available in three lengths, there are plenty of options for success.

Blister Prevention on Multi-Day Dive Trips

Blisters while freediving are often not a consideration for most divers, until they become a big problem. It makes sense that putting large amounts of force from kicking on our feet can cause blisters. The long fins that Freedivers use can compound this problem. There are a couple important ways to ensure blister prevention while freediving, and we will be going over some of those strategies in this post.

Booties – Blister Prevention while Freediving

Dive booties help prevent blisters and fill in your freedive fin foot pocket. They can also help on long walks to and from your dive site. Booties prevent blisters by adding an extra padded, protective layer, between your foot and the sometimes abrasive rubber of a foot pocket. A good neoprene bootie will help keep your feet safe from the environment around you. That can be anything from an underwater rock, to shells walking along the beach. Booties are the single biggest piece of equipment that can prevent blisters from diving. Make sure to always have a spare pair of dive booties in your dive bag to prevent skipping a day of diving, or ruining your week or month. If you have particularly sensitive feet you should consider wearing a thicker neoprene bootie.

Properly Fitting Foot Pockets

After dive booties, properly fitting foot pockets are critical to blister prevention. Foot pockets for freedive fins should be like an extension of your foot. They should be snug, but not tight. If you foot can easily move back and forward in the foot pocket they are too loose and can likely cause blisters. Make sure to get a comfortable pair of foot pockets that fit your foot well. If you are having a hard time finding a good pair of foot pockets that fit you, another good option is to use a pair of Fin Keepers to hold the foot pocket to your foot better.

Know When to Get Out of The Water

It is amazing how quickly your feet can go from completely normal to looking like ground beef. If you are on a multi day trip it ic critical to make sure you are taking care of yourself. That means staying hydrated, cleaning your wetsuit, and taking care of your feet! One of the toughest calls you can make on a trip is to know when to get out of the water. If you forgot your booties up in your room, just stay out of the water for a day. It is brutal to miss a day, but it beats missing the rest of the trip and having to heal up for over a month with major foot injuries. We speak from experience when we say it is not fun to spend more time than necessary in 3rd world clinics trying to pick up antibiotics for blood poisoning.

Putting Together a World Record Kit

Freedive spearfishing has been around for decades. The organization that maintains the standards and the records is the International Underwater Spearfishing Association, IUSA for short. This is the organization that maintains the rules for submission, weighing, and how you must land your fish for it to count as a spearfishing world record. We will be going over the basic rules and equipment necessary to submit a world record. 

Summarized Rules for Landing Your Fish

Spearfishing world records fall into four categories. Men’s Speargun, Men’s Polespear, Women’s Speargun, Women’s Polespear. These rules are obviously based on gender and the tool used to take the fish. Divers follow specific requirements in order for a fish to be considered for a world record. 

Equipment and Action Restrictions

The first rule is that the fish must be shot and retrieved exclusively while freediving. You cannot use artificial means of breathing such as scuba, Hooka, bail outs cannot be used in any part of the taking of a fish. You are technically allowed to get out of the water to get additional equipment from a boat or on shore. With that said you need to get back in the water where you left it. No short cuts to the fish allowed. The only help you can get from another diver is to receive an unloaded speargun. The diver that shot the fish then needs to load the speargun themselves for a secondary shot on the fish. You can to use chum and flashers. You need to declare the use of chum during the narration in your application. No powerheads are allowed to be used to subdue the fish.

Fish Conditions

Otherwise the fish needs to be wild and free swimming. Penned or netted fish can’t count towards a world record. Other than that you need to be following the law in the area you are spearfishing. The diver needs to shoot a healthy fish. That means it cannot be mutilated or damaged by other fish or another diver. The minimum weight to be considered a record is 10 pounds or 4.5 Kilograms for saltwater species. Freshwater species need to be a minimum of five pounds, or 2.3 Kilograms. You can enter any legal game species.

Fish Weight Requirements

For fish under 25 pounds the fish needs to beat the previous record by at least two ounces. Fish that weigh 25 pounds or more, need to be at least half of a percent more than the existing records weight to be considered. The example the IUSA gives is an existing spearfishing world record is 200 pounds. The challenger needs to be a minimum of 201 pounds to contest the existing record.

Weighing Your Catch

Ideally, an official weigh master weighs the fish. The fish needs to be clean from debris, like sand, dirt, or ice. Subtract the weight of any line used to secure the fish to the scale. A Certified Digital Scale is preferable because it gives precise measures, which the IUSA requires. Weigh the fish on a certified scale. The Scale’s certification needs to be current to within the past 12 months.  Alternatively, Certify your scale within two weeks of weighing the fish. If you have to weigh the catch at sea you need to have multiple witnesses write statements describing the highs and lows of the weight difference as well as the sea conditions. You should also provide a video with the application. 

Other Required Documentation

The legate and girth of the fish are critical in the application process. You need a tape measurer that does not stretch, even when wet to verify the fish’s measurements. For perfect clarity of the application process you need to look at the guidelines on IUSA’s official site. 

Short List of Required Gear for a Spearfishing World Record

  • Certified Scale
  • Static Tape Measurer
  • Pictures and Videos (SmartPhone)
  • Statements from unbiased individuals and witnesses
  • Rope for attaching your scale to a solid object or attaching your fish to the scale

The best practice is to keep everything you need to in one place, like a dry box or dry bag.

Storing Floatlines – The Struggle of Storage for Easy Deployment

Storing floatlines is always a struggle, and one of the big problems with using floatlines at all. Over the years we have come up with several means to help make storing floatlines easier. The biggest factors come down to space, storage space, and travel conditions.

Bait Sorting Basket or Bucket

One of the best ways to store a floatline is in a bait sorting basket. This works well on boats with plenty of deck space. The best way to store it is to rig up your floatline to your speargun first.  Then from the speargun side of the floatline flake out the line into the basket. From there you can attach your float to the other side of the floatline. To deploy you floatline you just need to put your float into the water and let the current do its work. The floatline should deploy tangle-free almost every time. 

The other benefit to the sorting basket is that it doubles for all of your equipment storage. It also has the benefit of draining well. If you have a wash basin after your trip you can basically just dunk the entire basket and be packed for the next trip. A 5 gallon bucket has similar functionality, bud does not drain well (usually). It does have the benefit of being useful in other, traditional ways. 

Figure-Eight With A Floatline Hook

If storage and deck space are limited you can use a stick after you wrap up the floatline in a figure-eight. The figure-eight prevents loops from getting tangled within the next loop of the floatline. It is not as effective as just flaking out the floatline in a limited space, but it does work.

The floatline hook can be placed in a fishing rod holder or hooked onto a railing or Bimini . It keeps the floatline out of the way while moving spots. You should make sure the figure eight is long enough that part of the floatline is resting on the deck of the boat. This keeps the figure-eight loops form unwinding into regular loops that can easily tangle. This is also a great way to transport your floatline in a bag. It prevent major tangles while traveling domestically, or internationally. It helps keep your floatline organized in your duffle or travel bag.

Figure-Eight On A Speargun

This is a good way to manage a floatline while shore diving. You can prepare this method form the comfort of your home. You essentially use your speargun as a rigid stick you make a figure-eight using the spear shaft and unloaded bands, the body of the speargun, and the handle to keep the floatline organized. No method is prefect, and is has its drawbacks. The biggest is that your floatline and speargun are not ready to be used as soon as you get in the water. You need to undo the figure eight manually, and gradually while you are in the water, This does not present and issue, until there are fish all around you as soon as you get in the water. This method of storage is highly discouraged for diving off of a boat for this specific reason. 

A Giant Tangled Mess

Anther option is to accept the giant tangled mess that is a floatline. This method is not recommended for several reasons. The biggest reason is that it can prevent you from landing big fish. This can be from the amount of time you waste trying to fix it in the water, or from actually shooting a nice fish and the resistance of a knot causing too much back pressure. Either way it is frustrating when it happens.

The other reason to try and keep it organized is to prolong the life of your equipment. Knots in a line are a natural weak point in any line. If you have a bunch of knots in your floatline it can compromise the integrity of the product.

The last concern is a tangled mess of a floatline should be your biggest concern. The risk of entangling yourself and drowning. You should be wary of any large loops in the water. If a large fish suddenly takes off and you are entangled in your floatline you have a real risk of drowning. Always keep safe in the water. 

How Frequently You Should Replace a Wetsuit 

There are several factors that can dictate how frequently you should replace a wetsuit. We will go over several of those considerations, as well as ways to extend the life of your suit. The biggest factor is the amount of use the it sees. After that the age is a big consideration. One of the biggest impacts on how long a wetsuit lasts is how it is cared for. 

Frequency of Wetsuit Use

Easily the biggest impact of how well a wetsuit works is how frequently the suit is used. Neoprene is a rubber that has small air pockets within it to help insulate a diver. The more frequently a wetsuit is used the more these bubbles get compressed and destroyed. These bubbles are what helps insulate the diver, more so than the rubber. If you are diving multiple times a week all year long your suit will compress, and be less effective sooner than if you only were diving once or twice a month. You can see how the amount you dive can dramatically impact how long your suit will last and how frequently you will need a new one. If you are diving multiple times a week you will likely need to replace your suit every year or two. 

The Age of the Suit

Even if you don’t use your wetsuit very frequently it still breaks down over time. The neoprene is a rubber, and it stiffens with age. Every once in a while you may have to buy a suit for a trip to somewhere cold. That suit may only get used every year or two, but it will still start to become less effective after a few years. Other than the neoprene getting stiffer, another factor in this is that these suits are held together by glue and stitching. That glue has a shelf life and will break down before the rest of the wetsuit. Even with effective stitching you will get water intrusion that makes the suit feel colder. Even if you take perfect care of your suit, they tend to loose effectiveness within about five years from when they were manufactured. 

Extending the Life Of your Wetsuit Through Proper Care

Taking proper care of a wetsuit can dramatically increase the life of it. One of the reasons wetsuits can loose their ability to keep a diver warm is from not being washed. We mentioned before that neoprene keeps a diver warm by having air pockets encased in rubber. Those air bubbles can become clogged with your skin cells, sweat, urine, and debris. As these air pockets get saturated with all of this they loose effectiveness to insulate you. Using wetsuit shampoo and cleaner and properly washing and drying your wetsuit cleans out these air pockets and extends the life of the wetsuit. DO NOT USE DISH DETERGENT. Any type of de-greasing soap will harm your wetsuit. Wetsuits are made of rubber, which is a petroleum product. If you use de-greasing detergent on your wetsuit it will start to fall apart.

How To Rig Bluewater Traditional Speargun To Breakaway

What Makes A Bluewater Speargun

The defining feature of bluewater spearguns is how they are powered, specifically how the bands are set up. Traditional Bluewater spearguns are larger and have between four to six bands to power the speargun. These spearguns are larger to compensate for the amount of force those bands provide. Generally speaking the number of bands adds power to the speargun, while the length of band pull adds to the range of the speargun.


Bands need to be the correct length to function properly. Most speargun rubber is powered best at a 350% stretch. That is not easy to load, but it is the best tension for a speargun to be powered properly. The way you determine the length your bands need to be is to measure the distance the band stretches. Use a tape measurer and measure from the back of the band slot to the loading tab on the shaft. Multiply that distance by two, because your bands go down both sides of the speargun. Divide that number by 3.5 to determine the length of your bands.

Spear Shafts for a Bluewater Speargun

Once you have the bands on you need to determine the right spear shaft for your bluewater speargun. You should keep the shaft overhang consistent across all of your spearguns. That means the distance from the tip of the speargun to the tip of the spear shaft should be the same from one speargun to another. That goes for flopper shafts of threaded shafts including the slip tip. Most bluewater spearing requires thicker spear shafts. That means 5/16”, 11/32”, or 3/8” thickness shafts.

Slip Tips 

The type of slip tip you use can make the difference between landing your fish and losing it. Generally you want to use a spectra slip tip for soft fleshed fish, like wahoo or mackerel. For other species it is best to use a cable slip tip. Super sharky waters may make a cable slip tip better option even with soft fleshed species.

Shooting Line

There are a couple different options for shooting line when rigging your bluewater speargun setup. Each type of line has its place. Most big bluewater species require a strong stainless steel coated cable. The coating doesn’t make the cable stronger, but it does make it easier for you to handle in the water, and is less abrasive on your gear. For Big Tuna or bill fish you need to double crimp your stainless steel cable. 

Spectra shooting line is also a great option, but is more easily cut on reefs or from shark teeth. Make sure to use a double-figure-eight knot when rigging spectra, because it is the strongest knot. A knot or splice are always the weakest part of any line.

Because bluewater spearguns have such long ranges you need to have two to three wraps of line on your speargun. The shaft will only travel as far as your shooting line. 

Floatline Breakaway Adaptors

We prefer breakaways because they are a sturdy option that streamlines your bluewater spearing setup. They present the opportunity to keep your speargun separated from your floatlines and shooting line, while keeping your shooting line tensioned on the speargun in the water. Personally, I prefer pigtail swivels because they have less chance of failure.
