Product description of C4 Predator Diving Fins

Description summary

Unleash your potential with the C4 Predator fins, 100% made in Italy. Ideal for novices and experts alike, these fins merge an ultra-light 250 footpocket with a soft yet highly reactive technopolymer blade. The advanced TPE polymer construction ensures maximum energy transfer, while integrated water rails provide superior stability and prevent drifting. Experience unparalleled comfort, efficiency, and power on every dive. Perfect for spearfishing and freediving, the Predator is your ultimate underwater advantage

PREDATOR Fins.

Manufactured entirely at C4 plant in Italy, Predator fins are made by overmolding a technopolymer blade with 250 foot pockets.

These fins are ideal not only for diving novices but also for more experienced spearfishermen and freedivers who want a light fin with a comfortable foot pocket, a soft but.

reactive blade, and who do not consider it essential to have a fin with a blade that can be disassembled from the foot pocket.

FOOTPOCKETS 250.

PREDATOR fins are equipped with the new 250 footpockets.

Thanks to the use of a TPE 75 ShA polymer, the energy transmission of the 250 footpocket to the blade is increased, thus obtaining highly efficient fins.

The study of the geometries has allowed us to obtain minimum thicknesses, allowing the weight of the 250 footpocket in size 41/42 to be reduced to just 250 grams.

BLADE PREDATOR.

We have sourced and tested a specific polymer to obtain a soft blade with high elastic return and strong resistance to breakage.

The presence of water rails in the final part of the blade prevents the fin from drifting during the kick, thus improving performance.

100% MADE IN ITALY.

All C4 carbon fiber blades have always been entirely manufactured in our production plant in Italy.

Starting this year, a new plastic injection department has been added at C4 plant and this is where the 250 footpockets and PREDATOR blades are manufactured.

PREDATOR fins are a 100% MADE IN ITALY by C4.

Lukas

They are very practical and wonderful for beginners. One thing they don't mention is that you need to buy soft-soled neoprene booties, however, they are a very good option for starting out. I recommend them to any beginner or even those who are not so beginner.

New technologies. The fins are very light, so much so that they float. The downside is that they are very hard to put on, the heel is hard, you would need a shoehorn.

The material is good and everything, the shipping was fine, but they were too tight, I'm considering getting a size larger and compensating with diving socks, it's better than them being tight, I have to return them and order a larger size!! :D:D

Very light, effective

Dan

Thr fins are very light compared with orher. I spearfished for 4 hours. I don´t dive deep, max 4m. I can build speed, snorkle easy didn´t need to compensate with weights. The size is acurate, I ordered my number and can use a 3mm sock. Great product

Incredible fins...!!!

Álvaro Lorca

"cucumber" of fins!!!! quality price more than incredible..... super professional fins for a more than affordable price. Just keep in mind that they fit big... I have a 43-44 and when buying them with this listing I have seen that they fit big so I adjust when purchasing and go one size lower. Good delivery service... and now we will see the exchange rate since 42-43 would be better for me. In general everything Excellent.

Super fins

My daughter wears c4 400 40/41 2mm socks, but can't get them on with 5mm socks. Looking for a pocket she can wear with 5mm. Should I go 42/43 or 43/44? How do the 250/300 compare with 400 to fit? Cheers

Yes, 42-43

Hi, how would it possible to take the fins onboard as hand luggage? Is it possible to fold it or needs to be straightened? Any practical suggestions? Thank you

Answer of Sarah

In my opinion they don´t stand a chance in hand luggage. I had them in my big carry-on suitcase and they were bent there. On holiday it takes a few hours and then they become smooth again.

Karoly

Sorry about the simple question but I’m totally new to free diving. Is the product foldable? Can I take it to the airplane as hand luggage? Do you have any suggestions how to transport it?

Answer of Alessandro

No absolutely not, being made of plastic it will crease, you need to have a special bag.

Answer of Dan Gabriel

The product is not foldable and cannot be carried in hand luggage. Transport is not easy, it will most likely have to be registered as special or sports luggage.

Answer of Sarah

No. You can bend them a little so they fit into a large suitcase in your checked baggage.

Hi.. is this fin best for freediving for beginner. How good this fin give propulsion. Is it lightweight . Regards Anip

Answer of TradeInn Expert

Dear, these were way too long for me

Answer of Alessandro

Yes for beginners it is great and it is quite light for being plastic...

Answer of Jérôme ou Jessica

Hello, There are better carbon fins for example, it is not the same budget. To start they are very good. For a plastic fin, they are very light and the foot pocket very comfortable. The propulsion is very good for soft. I use them mainly in the pool for freediving and target shooting (training and competition).

Answer of frank

Light fins and good propulsion. Sufficient for a beginner +. Low weight compensation required. (or even no compensation) Only downside: they deform when stored: curvature of the blade due to the great length, but propel well in the water Remedy: position them flat during storage and in a bag.

Ideal buyer profiles

Spearfishing Adventurer

This user is dedicated to spearfishing and requires gear that offers a blend of power, efficiency, and durability for successful hunts. They value fins that provide a strong, reactive kick without causing fatigue during long sessions in the water.

The C4 Predator fins are an excellent choice as their recommended use is specifically for spearfishing. The technopolymer blade is engineered to be soft yet highly reactive, providing a high elastic return for powerful and efficient propulsion. This allows for quick movements and sustained effort. The blade's strong resistance to breakage and the secure closed foot pocket design make them a reliable tool for demanding underwater environments.

Freediving Enthusiast

This individual practices freediving and seeks fins that maximize energy conversion into forward motion. They prioritize a lightweight design, a reactive blade, and a comfortable foot pocket to enhance their performance and extend their time underwater on a single breath.

These fins are well-suited for the freediver. The highly reactive technopolymer blade with its high elastic return translates kicking energy into efficient forward motion, conserving vital oxygen. The closed foot pocket ensures a direct transfer of power from the leg to the blade. The soft blade characteristic also allows for subtle, controlled movements, which is beneficial in freediving.

Competitive features

When selecting the right fins for spearfishing or freediving, details like blade material, foot pocket design, and overall weight make a significant difference. In this analysis, we're looking at the C4 Predator Diving Fins, a product made in Italy and specifically recommended for spearfishing. We'll compare them against several other popular models, including the Omer Stingray Evo and Cressi Gara Turbo Impulse, to see how their unique features stack up.

Where it excels

The C4 Predator fins stand out with their lightweight construction, with a specified fin weight of just 250 grams, making them easy to handle in the water. Engineered for performance, the fins feature a technopolymer blade with characteristics described as soft, highly reactive, and possessing a high elastic return for efficient propulsion. The closed foot pocket is made from a TPE 75 ShA polymer, designed to provide a comfortable and secure fit for effective energy transfer from the diver to the fin.

Consider alternatives if...

Divers who prioritize having a modular fin system should note that the Predator's blade is permanently overmolded onto the foot pocket and is not designed to be disassembled or swapped out.

Verdict

The C4 Predator Diving Fins are an excellent choice for divers seeking a lightweight, high-performance fin straight out of the box. Their Italian-made construction combines a highly reactive technopolymer blade with a comfortable TPE polymer foot pocket, making them well-suited for their recommended use in spearfishing. While they offer great performance, their non-detachable blade design means they are best for users who do not require the ability to customize or replace individual components.
