The Best Spearfishing Fins for Deep Water Spearfishing

Your spearfishing fins are critical for your effectiveness as a hunter. Having the best spearfishing fins guarantees a more relaxed and less energy-consuming experience. 

Many spearos ask, “is there a difference between freediving fins and spearfishing fins?” There’s a lot of similarities and overlaps. Competitive freedivers will opt for the best freediving fins for their use case of diving deep, whereas a spearo will have a different use case of conserving energy while hunting.

This can be possible if we gear up the right way so here are the best fins for spear fishers underwater: 

Best Spearfishing Fins for 2021

1. Cetma 

These are from 100% carbon fiber materials. The design allows optimized stiffness distribution, ensuring the maximum hydrodynamic efficiency of CETMA. So when you kick the blade with a certain frequency, you actually spend low effort to perform the thrust.

The stiffness available are Super soft (XS), soft (S), and medium (M). Thus, giving spearos the liberty to choose for their preference.

These fins are made from carbon using the infusion technology with an innovative double vacuum process. This makes the carbon fiber stand impregnated perfectly in the resin. Thus, your kicks form fewer microbubbles.

They have a thermo-rubber foot pocket that helps make your dive comfortable. Plus, the interchangeable blades allow you to change the long blade to your preferred stiffness. The fins come in (20) soft, (25) medium, and (30) hard blades.

These carbon fins will not tire out your legs when kicking on the surface for more extended periods. Plus, the blades push you most during descents and ascents, even in great depths.

3. Riffe/DiveR fins

The Riffe and DiveR partnered to produce a top of the line fin blade. These fiberglass fin blades have a “medium” hardness for the greatest performance. It has Veloc foot pockets for each 35-inch fin.

These fins have a custom epoxy resin system and aerospace-grade fabrics that transfer the load progressively from toe to heel. Something spearos would appreciate when deep underwater

With this fin, Cressi combined three different materials to guarantee an unsurpassable performance. They used special polypropylene for reactivity and lightness of the fins.

Additionally, a guaranteed perfect leg-fin thrust transmission is because of the soft elastomer. This elastomer anatomically wraps around the spearo’s foot. Spearos and some Scuba professionals consider these fins as one of the best deals in the market.

Gara 2000 HF by Cressi is comfortable to wear with or without neoprene socks. Aggressive freediving fin best for professionals of spearfishing and apnea diving. 

5. Leaderfins

How to Choose The Right Size

HOW TO Pick the Best Spearfishing Fins | Spearfishing 101

Choosing the right size for the foot pockets, you will first need to put on a thick sock. Many spearos and divers make the mistake of fitting a pocket without a sock on. When fitting, we always want to think of the worst-case scenario, so we advise you to fit with at least a 4mm sock on. 

Next, stretch out your foot, and put it in the pocket. Position your foot as you would in the water. Do not stand on it as you never stand on your feet underwater. This is a common mistake when fitting, which leads to the spearo purchasing the wrong size of fins. 

When you have the foot in the pocket, you try to feel the fit. You want a nice pressure and not one that restricts your foot’s movement in the fin.

How to Mold Your Fins

You can modify the size of some pockets in the market to expand as they are moldable, but they do not shrink. They can only expand. That’s why some spearos buy pocket fins that are a bit snug as they expand over use. If you want to mold your fins before your trip, you can:

a.) Boil water, and put your pocket in until soft. Take it out, and put your foot in with double socks. Cool it before taking your foot out. Keep in mind to mark which side of the foot you’re molding as the fins can become confusing after the process.

b.) Use a blow dryer carefully to soften the pocket before putting your foot with double socks in. Repeat the same procedure as mentioned above. Remember that you don’t want to leave the blow dryer in one spot for too long as it will melt that specific spot. 

Factors In Choosing Spearfishing Fins

Choosing spearfishing fins is trickier than most divers make it out to be. You don’t essentially need to have the fanciest type to be able to go down underwater. There are many aspects of your dive that should influence your choice. 

If you have the money to spend on carbons, that will save you a lot of energy down underwater kicking, but it is not 100% necessary. You could get away with a Fiberglass and even a plastic fin depending on your dive’s depth. 

When fishing to a 5 to 30-foot range, keep in mind that you’re going to kick around rocks and big boulders. That is if that’s the type of diving you want to do. If your concern is efficiency, choosing fins made from efficient materials will definitely be a significant factor. 

Basic Fin Information 

If you are an amateur spearo and don’t have much idea about diving gears, specifically the fins. Here are your basic fin infomation to help you choose the best fin for each foot. 


With fins, there are essentially three kinds of materials to choose from. The first are those made from plastic. They are typically the most common because of their affordability. However, aggressive diving will put these types to shame as they do not perform up to par with the other types.

The second and third are fiberglass and carbon made fins. They are superior to plastic when it comes to power and price.


The hardness of your fins influences your performance in the water. That much is true. The less the fin’s hardness, the easier it is to kick as there is less resistance. But as the hardness increases, so does the force the fins generate. Lastly, there is the middle ground, medium fins, which have soft and hard aspects. 


Pockets are the space on the fin where the foot settles. If the blades of your fins are interchangeable, chances are, so as the pockets. This feature allows the comfortable performance of your fins without you having to buy a new pair. 


Long blade fins are indeed ideal for many average divers and spearos. But if you’re the type to challenge yourself or when the time comes that you will become a pro-spearo, specialty fin may be fun for you.

Monofins are single fins that are like that of a whale’s tail. It is difficult to maneuver as it is a large fin. Yet, with constant practice, these fins can take you deeper into the water. 

Spearfishing fins vs. Scuba or Any Fins

Spearfishing fins have longer ribbed blades rigid enough to propel you with power. Thereby covering more distance with less time, oxygen, and energy from the spearo.

What’s more, is the power they drive is proportional to its length and material used. Maneuvering these fins take individual skills. They are not advisable to use in close to reef or tight spaces exploration.

These fins generally need more leg strength as the kick may be more demanding due to the fins’ stiffness. But as you get used to the technique of maneuvering these fins, your muscle strength grows. They pay off in power and guarantee a less energy-consuming experience. 

Scuba fins aim for more power in the water as the equipment weight and volume make you less hydrodynamic. They are designed for more challenging water conditions. These fins come in varied lengths and flexibility. But they are typically shorter than spearfishing fins and longer than snorkeling fins.

They propel with more power than the snorkeling fins. But less than that of what can spearfishing fins give you. They have an open heel foot pocket design as opposed to the usual full-foot pocket design of spearo fins. 

Snorkeling fins are flexible and light. They have shorter blades for easy maneuver. Thus, needing less strength to paddle on or below the water surface. These fins are safer and convenient. They give you less chance to accidentally kick someone or damage the coral reef you’re swimming near on.

Additionally, these fins allow snorkelers to go in and out of the boat, or even walk right onto the beach. But they are only efficient for swimming on or below the water surface. Using them in spearfishing, you will need more energy than you’re supposed to use. This does not constitute an enjoyable experience. 

Frequently Asked Questions

What are the best fins for freediving?

There are many fins to choose from. Choosing the best freediving fins essentially depends on many things. Consider the type of dive you plan to do, your skill level, and the environmental condition. (link to CS free diving article) 

Why do freedivers use long fins?

Longer fins mean more power to propel you under the water. Spearos and freedivers alike benefit from these fins in energy, time, and oxygen. 

Can you use freediving fins for scuba?

If you scuba dive in a less crowded area, you may use these longer fins. But if you are diving in a bit crowded or tight spot, try to think of everyone’s safety and the coral reef as well. 

What are the best fins?

Choosing the best fins essentially depends on what you need it for. Is it for scuba? Freediving or spearfishing? Snorkeling? These activities will need different types of fins as the conditions in each are different. 

Insider Advice

Whenever spearfishing California or Baja, it is helpful to have a backup fin with you or a fishing buddy with a backup. We can never tell if we will lose things or break things while spearfishing with time and place.

If you think plastic fins don’t break, they do. And if you can take a special carbon fin with you, bring it. This makes your experience more relaxed, and the diving will take less toll on you.
