Before looking for the best brand of spearfishing fins, you need to know the fin features you should look for when hunting underwater.
Here is your basic fin information to help you choose the best set of fins.

Basic Fin Information
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.
Fiberglass fins sit between plastics and carbons. Fiberglass will give more pop than plastics but not as much as carbons. They will be a little heavier than carbons and depending on the manufacturer will be roughly the same in terms of durability. They will be cheaper than carbons, which puts them in a good spot for those looking to upgrade from plastics but can’t shell out the money for carbons.
Carbons are the higher-end dive fins. Depending on the manufacturer the responsiveness can vary between the different models. They will have the best energy transfer as well. Their price is the part that hurts more beginner spearos so stick with plastic or fiberglass until you start diving in heavy current or know how a bit better what you’re looking for with your gear.
Fins come in a spectrum of stiffnesses from extra soft to hard.
The hardness of your fins influences your performance in the water. The less the fin’s hardness, the easier it is to kick as there is less resistance. If you’re a heavier person you’ll need stiffer fins for better energy transfer for thrust. However, if you have too stiff of fins and you don’t need the stiffness, then you’ll just be wasting energy.
A foot pocket is a space on the fin where the foot settles. If the blades of your fins have an interchangeable design, chances are, so do its pockets. This feature allows the comfortable performance of your fins without you having to buy a new pair.
Some pockets allow the fins to reach to your heel which will give you better energy transfer. Some also float, making it easier to stay horizontal while you’re breathing up.
Some spearos like to freedive the line as training. There certain fins that allow for better cross-over between the two activities. If you plan to do freediving, look for a longer blade that will help you conserve your energy while kicking.
What To Look For In Spearfishing Fins
When spearfishing, you want to use a long blade rather than stubby scuba style fins, to give you more efficiency with each kick, allowing you to save more oxygen and energy for your hunt.
The extra length in the blade will help you dive deeper as it enables you to deliver more returns for each of your kick. Unlike the fins you use for a scuba dive or snorkel, which are typically much shorter, spearfishing fins require more area to help propel you into the water.
Your fin’s full foot pocket is designed to give you the most efficient way to get that energy from your foot to your fin’s tip.
Ensuring that the foot pocket has a perfect and comfortable fit as a loose one will let you expend more energy into kicking it hard, and a tight one will cramp your feet. Non-removable foot pockets don’t allow you to upgrade the blade without changing the whole fin.
When purchasing the right fins or gear, it all comes down to your preference at the end of the day while taking into account the basic rule and the type of dive you’re going to be doing.
Essentially, if you weigh at around 165 lbs or less, you can use a softer fin for spearfishing. If you weigh 165 to 200 lbs, you want to use a medium stiffness to provide you with a bit more material weight to work with.
If you weigh more, you can use the fins on the stiffer end to give your strong legs the weight to help propel you into the water. When spearfishing in the water where there are many currents, opt for medium stiffness to take you deeper into your dive.
Plastic Fins Vs. Carbon Fins
Plastic fins lean more on the cheaper price while being super durable and beginner-friendly. With plastic fins being durable, they have the disadvantage of being heavier, tiring your legs more on your dive.
Carbon fins are lighter and more reactive than plastics, allowing you to conserve more energy and oxygen while still going deeper. These fins tend to be more expensive compared to plastic.
When in doubt, just remember that a lot of great spearos started with plastic fins and still use them for shore diving lobster when they don’t want to damage their nicer fins.
