鳍101.

Using fins to help us move faster and easier through the water is not a new idea. By adding fins we are adding extra surface area to help push us through the water. Our legs are then able to provide most of the work that lets us move more streamlined and efficiently through the water without creating drag from using our arms.

鳍的发展及时回归，一路从古代到莱昂纳多·达芬奇，从19世纪初到法国海军到本杰明富兰克林捆绑椭圆形木头到他的脚，在马萨诸塞队游泳。这些天，Fin技术是一种科学 - 也许也许是所有漂亮颜色，形状和设计的艺术。Fin工程师具有成形翅片，以模仿不同物种的翅片，如鲸鱼尾巴，并添加分裂和开口腔室，以允许水通过而不会导致潜水员尽可能地工作。1zplay添加角度并使用不同的材料。所以现在真正的问题是，“我如何选择哪种鳍最适合我？”

打开脚跟与全脚

翅片之间的一个主要区别是它们是否有足部脚袋，脚坐在脚踝周围的带子上的脚跟或带有肩带的开放鞋跟。全脚鳍不需要靴子（尽管湿衣服靴/氯丁橡胶袜子可以磨损）。这些翅片通常重量轻，提供更少的功率，使其成为浮潜或在平静的水条件下潜水的理想选择。全脚鳍通常有几种尺寸对应于鞋尺寸，并且找到一个舒适的贴合来说，这是一个不太紧张或过于松动的舒适合身，以防止摩擦和水泡。

Divers usually prefer open heeled fins because they provide the most power in the most conditions. They are usually thicker and sturdier, providing more power for divers who need to move themselves and all their gear through the water. The extra power they can provide is important in the event of something like a current or swimming a longer distance.

Shore diving usually requires open heel fins because they have the larger foot pocket for boots that will protect your feet while entering and exiting the water, and while carrying heavy gear. They are also better for cold water diving, where the warmth of the boots is required.

The straps that wrap around the ankle are usually adjustable and have quick release buttons to remove them. Normally open heel fins come in only a few sizes such as small, medium, large, and extra-large, based on the size of the foot pocket. To find the right size, they must be tried on with boots, because boots can have different thicknesses and therefore require a different-sized fin depending on the boot.

形状，尺寸和材料

Fin shape can alter the efficiency in which a diver moves through the water and the amount of energy a diver must exert to move the fins. Traditional fins move the water up and down creating thrust; the more surface area, the more power can come from the fins. Some fins have holes in the blade; these vents and channels have been incorporated into fins to help move water through the fins and reduce stress while kicking, but without losing the power from the kick.

Each brand has its own design for the best performance. Some fins have been shaped after marine animal’s fins such as Scuba Pro’s Sea Wing Novas, which are modelled after a whale's tail. Aqualung’s Slingshot fins have silicone “power bands” in the fin blade that help load energy like a rubber band on the up-kick and release on the down-kick to provide extra power.

The larger the fin blade, the possible the power. Free divers often use fins that are very long (2-3ft long blades) because they are trying to swim as far and as fast as possible, and the long fins give them the most power. Scuba divers usually don’t use free diving fins because most diving involves moving slowly through the water and free diving fins can also damage the reefs if used improperly because they are so long.

Fins are made out of several different materials to be durable and flexible including neoprene rubber, silicone, plastic, and combinations of several materials. Fins should be flexible and ridged enough to get power from each kick. Often the foot pockets are made out of a softer material such as neoprene rubber and the blades from plastic to be comfortable and powerful at the same time.

鳍也有各种颜色。选择颜色可以是个人偏好或一种让您更加可见的方式。明亮的黄色鳍比黑色更明显，一些潜水导轨喜欢佩戴鲜翅片或多种颜色的创意组合（右侧的红色，蓝色在左侧），以帮助区分自己水下。1zplay
