Split Fins - A Powerful Design!

Split Fins

A lot of engineering has gone into making scuba flippers more efficient. Of all the newer designs, the style, pictured to the left, is the most popular. Each flipper has a vertical sliver (some wider than others) taken out from the middle of the blade. The advanced design allows these fins to cut through the water like a propeller on a boat. They create suction and lift, which produces smooth forward propulsion. Instead of accumulating on the top of the flipper, water escapes via the vertical slit and creates a channeled force that pushes the diver through the water.

PROS:

•Efficient. You are able to cover more ground in fewer strokes. Many regard this fin as the most efficient flipper on the market.

•Clean. Because of the vertical slit, they cut through the water very neatly.

•Speed. You are able to move quickly through the water because of the diminished drag.

CONS:

•Versatility. Although the split flippers are regarded as highly efficient, there is much debate about their versatility. Many think that they have poor maneuverability and that they make the frog kick technique difficult.

•Cost. Although you can usually find this flipper design for a reasonable cost, you will still pay more than you will for the basic styles.

Horizontal Split Fins

These flippers are very similar to the vertical version, except (you guessed it!), the slit goes side to side. The engineering on this type of design pushes water back, instead of up and down, as on most of the other styles. It is said that if you like the ease of the kick and lift principles of the originals, but don't like the idea of giving up maneuverability, than the horizontal style would present the best of both worlds. The inner blade on the flipper smoothes and stabilizes, while the outer blade and flex rails maximize speed and propulsion.

The new technology can become overwhelming for new divers trying to choose the right equipment. Just remember, as with all scuba equipment, you need to find what works best for you!
