A little Information On Diving Fins
In scuba diving the main form of propulsion is achieved by using our legs. Fins provide a larger surface area in the form of the blade, allowing you to move through the water with greater efficiency and ease. Reducing the effort needed to propel yourself and therefore conserving your energy.
Fins come in two main styles, open heel with adjustable strap and closed heal,both of which come with many variations. When choosing fins the diver needs to consider their physical strength and the geographical location in which they will be diving.
Open Heel Fins
Open heeled fins with adjustable straps and quick- release mechanisms are generally the choice of recreational and professional scuba divers alike as they allow the diver to wear booty’s and in most cases are stronger and larger than the closed heal variety. These are important points as generally we dive in temped waters and the boots offer insulation as well as protection from the environment. The fully kitted up diver also needs a strong well sized fin to help propel them through the water.
Closed Heel Fins
This style of fin is more commonly used in a warm water environment, when insulation is not required and for snorkelling. Generally they are less rigid and have a smaller blade than the open heel design.
One of the most innovative designs in recent times has been the split fin. This fin is designed much like that of a seal or a whale’s tail. The theory behind this design is that when the diver kicks more water is forced back along the fin with reduced resistance and drag, making the fin more efficient. Nature`s design is without doubt superior to our own, however split fins are not suitable for all styles of diving. Tec and cave divers use varied styles of kick to propel them through tight awkward spaces and the full fin style is more adaptable in these occasions.
Long Blade Fins
This type of fin is commonly used in free diving (where no scuba is used and the diver holds their breath) and in various aquatic activities such as, spear fishing, fin swimming and non-scuba underwater photography. They are generally made of neoprene and of an ultra-soft blade. These types of diving are highly specialized therefore require specialized fins and training in and out of the water to master. However, once mastered they offer another dimension in diving, by connecting the diver with the aquatic world in a silent more personalized way.
