A spearo/free diver’s fins should comprise of a full foot pocket with a blade that is much longer than that of a standard scuba diver. The difference between the scuba diver and freedivers fin is that one is designed for torque while the later is made with shear power in mind. Because a free diver is diving from the surface to the bottom constantly he/she needs to have enough power to get down past the negative buoyancy depth and then have the ability to lift off from the bottom to return to the surface. Freediving/spearfishing fin blades come in various stiffness levels to suit the beginner through to the experienced diver. Probably the most important thing to consider here is a comfortable correct fitting foot pocket and if it is not then your diving will be greatly affected not to mention the possibility of cramps which can also occur from too stiffer blade for your leg. It is also necessary to wear neoprene socks in order to prevent any chaffing of your skin. Finding the right foot pocket for your feet can be a real problem. Blade types also differ and can be made from either plastic or carbon fiber which will give you more power than standard plastic blades with less effort. Having the right fin will offer you increased dive times as well as better lift of the bottom when departing for the surface.
