Are you considered a "pig teammate" when diving? The air in the gas cylinder (many people call it oxygen cylinder) is always consumed faster than others, so it has to go ashore ahead of time.
Why is that? A big possibility is that you didn't choose a flipper, because the efficiency of the flipper directly affects the speed of air consumption in diving time and space, so we must choose a suitable flipper when diving!
So how do we choose flippers?
When using the set foot style, the whole foot is put on the foot like a shoe, and it is usually used with a specific sock.
Small and light
If the foot size is not suitable, it will hurt the foot
To buy a set of flippers, you must buy the right foot. When you stand up with your toes, the flippers will stick to your heels, not fall into the water.
If the flippers are not suitable, they will grind and even scratch their feet, so do not buy the improper toe binding flippers.
You must put on a pair of diving boots before putting on the fins.
Adaptable to a variety of foot sizes
More complex to use
Bifurcated fins: when you swim, the blades can generate eddy current in the water. Even if the propulsion force is very small, the bifurcated blades can open and allow the water to flow.
3. Easy to use, more suitable for novice divers
Paddle type flippers: paddle type flippers have existed for many years, characterized by the ability to produce gurgling sounds.
2. Suitable for various environments
2. General propulsion

3. How to choose flippers?
1. material
Flippers are mainly made of rubber, thermoplastic, glass fiber and carbon fiber.
Rubber flippers: due to the elasticity and density of rubber, they are very suitable for beginners and dominate in scuba diving.
Thermoplastic flippers: due to the molding method of plastic products, it has the characteristics of changeable modeling, colorful, light and cheap, so it is the best choice for free diving beginners and fishing and hunting enthusiasts.
Fiberglass fins: high cost performance, high durability, poor resilience compared with carbon fiber.
Carbon fiber flippers: they are the most expensive ones. They have better toughness and resilience, provide better power, and have low weight. They are basically prepared for professional players and senior enthusiasts. It can bring users a sense of pleasure, which is not really comparable to the first three materials.
2. length
3. soft and hard
If the fins are easily bent 90 degrees, they can't provide enough power for you; if they can't be bent to 90 degrees, they may be too hard to use.
In fact, the problem of softness and hardness depends more on personal preference. Some people like the feeling of strong kicking water, so the flippers with heavy weight of full rubber are undoubtedly suitable. But some people like the feeling of more fit between soft and water, so they can choose the relatively portable and light plastic flippers.
Here is a way to test the hardness of the flipper: put the blade and the foot sleeve on the shoulder, and then hold the front end of the flipper with your hand and try to bend it 90 degrees, which should be difficult under normal circumstances. (Note: some fins are not suitable for this test method)
4. Selection of shackles
Choose quick shackle and spring steel strip?
There is no more advanced difference! Usually, the standard configuration of flippers is quick shackle, that is, the buckle on and off quickly, which makes it very convenient to put on and take off flippers.
4. How to test your chosen fins?
After choosing the flippers, it's better to try them on in the swimming pool provided by the dive shop to see if they really fit you. You can test the following 9 aspects:
