Types of fins
Experienced divers note that the best manufacturers of the product are: Cressi, Mares, Scorpene, Omer, Leaderfins, Sporasub. Representatives of rescue services give good reviews to the products of these brands.
Fins for diving
This category includes popular models that are used for professionals and Amateurs of underwater diving. They differ in length and stiffness. Sometimes they are equipped with corrective blades and laminators, which make it possible to make a change in the flow direction and increase the maneuverability of the swimmer.
- length for increased maneuverability;
- the heel is designed to be comfortable as well as ergonomic;
- keep up the great work;
- equipped with blades and flow laminators;
- availability of a large range of models.
- more expensive;
- they are intended for use in a narrow specialization.
Fins for underwater hunting
These models are quite long, they are based on a combination of materials that contribute to changing the degree of stiffness of the fins, allowing you to speed up movement. They have a broken design: the horizontal blade is deflected by 10 or 15 degrees – this increases maneuverability. The products are equipped with an adjustable backdrop, which makes their landing on the feet more reliable.
- have a long length;
- they stay on their feet comfortably and ergonomically;
- the blades have a broken design relative to the horizontal at an angle of 15 degrees;
- dark camouflage products are produced: they have a variable degree of stiffness due to the combination of different materials during the creation process.
- more expensive;
- it cannot be used for Amateur use or diving.
Fins for snorkeling
Snorkeling is diving into some depth using a mask and snorkel. The fins used in this case are not very heavy, having compact dimensions, as well as comfortable and convenient to use.
- comfortable fit on your feet;
- operation without skills; small size; inexpensive.
- only the “tourist” option, cannot be used for professionals.
Fins for children
Models of fins designed for children are similar in design to fins for snorkeling, the difference is shown in the size. They are short, it is good to use them in the pool or sea. You can buy them for your child to teach him to swim.
- suitable for people who can’t swim;
- they are conveniently fixed on the feet; universal in use.
- it is not recommended to buy “for growth”.
The design of the fins seats
- The adjustable fins created with an open heel are equipped with a rubber tie, so they are considered ideal for snorkeling and Amateur use. Open type fins can be used for different foot sizes. At the same time, the fixation is considered insufficiently rigid, there is a risk of being left without fins if an object is caught underwater.
- Non-adjustable products with a closed heel contribute to a reliable, as well as tight fixation of them on the feet. This design is well suited for Amateurs to swim at an intense pace, they do not move on their feet. It is necessary to make a responsible choice, taking into account the thickness of the thermal socks used, if they are equipped with them. They are not purchased “for growth”. They are the best view for diving, as well as for spearfishing.
- The moon last is designed for highly specialized use only in acrobatic tricks and sports. It allows you to significantly increase your speed. The product is made in the form of a wide blade, which is driven by both feet in accelerated motion. Fixation on the legs is carried out using rubber socks.
Material for the production of fins
- Carbon fiber, or carbon fiber, is a very light, comfortable, and functional material. It is used to create the most expensive fins, advanced in technical terms.
- Rubber. Cast-in-place products are made from this material, and they can also be different in physical parameters. This is a budget option, at an inexpensive price, is in demand among fans.
- Plastic. Advanced material that is used in the manufacture of products that have an average selling price.
Fins size choice
- Short — (about 0.6-0.7 m) – great for snorkeling, as well as active recreation in the beach season.
- Medium — (0.7-0.9 m) are versatile, well suited for use for diving, and spearfishing too.
- Long ones (1 m or more) are used for scuba diving, spearfishing and diving.
Selecting the fins size
- For a holiday at the sea. When relaxing on the sea, you can make dives of 5-7 meters. The water surprises with its crystal clarity and lush vegetation. Long products with plastic blades are optimally suited. The design for accelerated diving and surfacing consists of blades and laminators. The open heel provides an opportunity to fix them tightly, based on the desired size of the diver.
- For underwater hunting. For this purpose, hunting fins are used, which are created with a length of 0.9-1.1 m. They have a closed heel, made of materials with different degrees of rigidity. Their blade is made at an angle of about 15 degrees, which contributes to a fast deep-sea dive.
- For the pool. The best option for the pool is considered to be short fins designed for snorkeling. They are created with an open heel, have a blade length of 0.5-0.7 m. their Blades are made of plastic or rubber. This is not suitable for those who want to practice swimming and diving techniques in the pool. They need to use the main fins used by the diver for deep-sea diving or spearfishing.
- For a child. Pick up the child’s short fins with a length of 0.5-0.6 m with an open heel. After the baby has mastered swimming skills, it will be possible to make a choice of other suitable models.
- For diving and snorkeling. For diving, fins are slightly different from similar products for snorkeling. Powerful and long, designed for diving enthusiasts, are made of carbon fiber or plastic. For those who are engaged in snorkeling, short ones with an open heel are suitable, equipped with a blade length of 0.6-0.8 m. Using compact fins for diving and Vice versa, the functionality of the design will not be effective enough.
How to choose diving fins?
The main purpose of fins for diving is to provide movement and maneuvering of the underwater swimmer. In order to understand which fins are better and how to choose fins for diving, we need to learn more about the environment in which they are used.
Water is a liquid substance that is almost 800 times denser than air. Oddly enough, this is both good and bad news. The bad news is that the viscous density of water creates a so-called drag for anybody that moves in it, which requires an effort to overcome it.
The good news is that it is the density of water that allows you to use it to make movement. In order to move forward, you need to create a force slightly greater than the resistance force. Here is for ensuring this movement and responsible fins.
As you may have guessed, the effectiveness of our direct movement depends on the effectiveness of the interaction of fins for diving with the water environment. This is why there are so many models on the market of the dive industry.
After all, every manufacturer believes that it is the design of its fins that is more effective. In fact, there are two rules that must be considered in order to choose the right fins for diving.
First, in each type of underwater activity, one basic design of fins will be effective. This means that fins for diving and fins for free diving or spearfishing are not the same.
Also, fins for recreational diving and fins for professional and technical diving also have serious differences.
First select the preferred type of activity and focus on a narrow segment of fin models. In the same way, we will drop the fins for spearfishing and freediving in this review and focus on choosing good fins for diving.
The first thing we will determine is the type of galoshes. As a rule, there are two options – a whole galoshes and a half-galoshes. The first option is intended for dressing the flippers on the barefoot. This is a pronounced recreational (Amateur) version of fins and it is widely used in dive centers for rent or often used for beach diving.
The second option, with a half-galoshes, is the most common among both Amateur and professional divers. In the second case, the foot is inserted into the galoshes for half or a little more, and the heel protruding from behind is pressed by an elastic strap and thus securely attaches the foot to the fin.
The option with semi-galoshes is worn on diving shoes – it can be both neoprene wetsuit boots, and boots or dry wetsuit boots.
From a practical point of view, flippers with half-galoshes are more preferable, since the use of such flippers together with shoes provides greater comfort when paddling and also boots protect the feet from damage (for example, against corals).
Galoshes of flippers can be more or less elastic, but make sure that excessive elasticity does not lead to a loose leg. Structurally, the galoshes can be wide, with a different amount of foot lift, and also different depths. Fitting fins (preferably on your bots) will give you the correct answer “they are yours or not”.
Pay attention to one nuance, when you try it on, as a rule, your bot is dry and perhaps because of friction, the galoshes will not be very much put on, but do not rush to immediately increase the size.
Keep in mind, when the bot is wet, it will easily slip inside, and also, wet neoprene will be more elastic and this will give the foot more freedom inside the galoshes. Dangling flippers are very bad!
Feel the flippers on your foot, wait a couple of minutes, let the foot get used to the crimping. Move your leg to simulate paddling movements, make sure that the flippers do not dangle when you shake them sideways. If the fins are too tight on your toes, and even after a couple of minutes you don’t feel comfortable, then change the fins – they are not yours.
The next typical parameter when choosing fins is the material from which they are made. As a rule, we can find three options on the market: fully plastic flippers, combined flippers (with plastic and elastic inserts), and rubber flippers (or flippers made of monopren).
In order not to waste your time and not to mislead you, we will immediately remove models made entirely of plastic from further discussion. These fins are usually very old models that have nothing to d o with the concept of efficiency.
And so, the combined blades of the fins are made of several parts, different in terms of stiffness of materials. Often these are plastics and soft polymers (sometimes resembling rubber).
The peculiarity of the combined blade is that during the stroke, elastic elements allow the more rigid parts of the fins to form a jet tunnel, creating a directed stream of water with a high efficiency.
In addition, sometimes elastic elements can adjust the degree of stretching and thus, with a more energetic Mach, slightly increase the area of the blade and create a short-term jerky effect.
Of course, the performance of the fin blade for diving will also depend on the overall stiffness. It should be noted that excessively soft fins can “slip” underwater, and excessively hard ones can create discomfort for an untrained diver and even reduce the leg muscles.
The next type of fins are rubber fins for professional or technical diving. It is not strange, but today a large number of Amateur divers switch to professional flippers after a while, and there are several reasons for this.
First, fins made of high-quality materials such as rubber or monopren have an almost eternal design and unlike combined and plastic fins can not break directly underwater. Yes, Yes-precisely break, from a large load on the blade.
Secondly, the design of professional flippers is such that they have a slightly shorter length and at the same time a slightly larger width, which provides an accurate application of force from the foot to the “push point” of the blades.
In other words, if the force of the push is comparable to other models, the diver uses a smaller amplitude in professional flippers and as a result spends less force on the stroke.
Thirdly, the design of the blades professional last includes three elements: the blade with a differential change in the thickness of rubber from the galoshes to the tips of the blades, and in the transverse direction, lateral “winglet” stiffeners ensure the formation of a jet of water flow and hydrodynamic channels provide two functions in the professional flippers – with a strong stroke, the mass of water that is not effective for pushing is removed into these holes and this makes the movement feel easier, and with fast and short jerks, dynamic channels prevent the disruption of the water flow that occurs from swirling microflows and thus provides high efficiency even with a small amplitude of movement.
You can still list many advantages, but we need only add that this kind of fins are widely used all over the world among professionals, cavers and those who explore sunken ships not only from the outside, but also deep in the holds.
In recent years, manufacturers of Amateur equipment are increasingly producing models similar to professional classics and this fashion is not for nothing, because the effectiveness proven for decades is truly appreciated by all divers, regardless of age and scope of application.
If you are currently in a search and you want to buy effective fins for diving, then take your time-study the market and find out how to choose fins for diving, ask your friends to give fins for the test. And remember what we said at the beginning of the article. Even if someone thinks that some model of flippers is perfect, this does not necessarily apply to you. Simply try.
As for the price, good combined fins can not cost less than $150, and good professional fins start from $180. Although recently on the market there are decent copies of semi-professional fins made of rubber and monopren at very interesting prices (from $100).
The main function of the fins
Is it possible to swim without fins? Undoubtedly. You can dive in a mask and without fins, enjoying the beauty of the underwater world. But everything changes when we put on scuba gear.
The weight of the cylinders underwater is small, but the mass, i.e. the inertia force remains the same as on land – about 20 kg. In addition, rigid cylinders restrict the freedom of movement.
The use of fins compensates for the difficulties encountered. Properly selected, comfortable, and effective fins largely determine the comfort of the diver underwater.
To assess the suitability of fins, we will select two parameters:
- ease of attachment to the leg;
- efficiency when swimming.
The first is determined by the design of the galoshes, the second – by the design of the blade and the General shape of the fin. The variety of designs of galoshes is reduced to two basic options: fins with closed and open heels.
The first are very convenient when putting on the barefoot and provide the most dense connection of the fins with the foot. It is more convenient to use open-heel flippers with a strap for putting on wetsuit boots.
They are also called regulated. Modern models of adjustable fins allow you to tighten and loosen the strap directly on the leg. The diversity of designs of fins blades is very large.
For fins, as for any engine, the efficiency factor is extremely important, i.e. the ratio of useful work to the energy spent. Underwater, everything is measured by air: the more energetic the physical work, the more it is consumed.
The more effective the fins, the less air is needed to cover a certain distance. All other things being equal, the efficiency of fins and their compliance with your individual characteristics can change the airflow rate by 20-30%. Accordingly, the time spent underwater will change by the same amount.
Excellent hydrodynamic properties have long fins with blades made of thin, elastic, and fairly hard plastic and rubber galoshes.
In terms of speed qualities, these fins are superior to the vast majority of other models and are optimal for swimming without scuba gear. It is no coincidence that underwater hunters around the world prefer the fins of this design.
Scuba divers, on the contrary, very rarely use them, since they lose to fins of a smaller size in maneuverability. For swimming with the device, fins with less long blades made of a similar material are produced.
Another way to increase efficiency is to use fins with Windows. What is their meaning? During the stroke, a zone of high pressure is created on one side of the rowing surface, and on the other – a low pressure.
The resulting eddy currents at the edges of the fins create additional resistance. Cracks in the base of the blade allow water to pass through, reduce the pressure difference, and thus weaken the vortex flows.
This design does not increase the speed reported by the fins, but reduces the effort when paddling. Significantly increases the efficiency of fins when using the tunnel effect. During the stroke, a certain amount of water inevitably rolls to the sides, not participating in the creation of the forward movement of the submariner.
If the inner part of the fin blade is made of a softer material than the side parts, then when the fin is paddled, it bends, forming a chute that orients the flow of water in the desired direction, thereby reducing the amount of water that rolls idly.
Another way to create a tunnel effect is to divide the plastic blade 2-4 longitudinal rubber grooves that allow transverse bending.
A variation of the tunnel effect is the spoon or bucket effect, achieved by a wedge-shaped insert of a softer material or rubber grooves of different lengths. Today, fins with tunnel effect are most popular among scuba divers.
How to use fins instruction
If the fins do not have metal parts, it is not necessary to wash them with fresh water after each sea dive, but it is advisable to do this before a long break-in operation.
Do not leave them in direct sunlight for a long time, do not dry them on a stove or other heating device, and avoid deformation during transportation and storage.
For the latter, do not neglect the use of plastic inserts in the galoshes included in the delivery package. If you follow these simple rules, flippers will serve you for many years.
