Have you wondered why your dive leader used a weird frog-style kick instead of the flutter-kick? Do you stir up so much silt that visibility drops to hantu-level when you “lift-off’? Turning underwater is awkward and unglam?
Now that you’ve mastered buoyancy control, it’s time to do something about your finning methods!
Standard Flutter Kick
The kick we grew up with, the one kick to rule them all! Forward thrust is provided by the downwards strokes. It’s most effective when legs are kept more or less straight, but it seemed that new divers tend to do a bicycling movement rather than a standard long upward and downward stroke. Learn to do it the right way!



Modified Flutter Kick
In confined spaces, the knees can be bent at right angles (thighs parallel to the ground), strokes shortened and propelled using mainly the ankles.
Pros
Powerful and fast (esp. against a current)
Good on the surface
Cons
Stirs up silt when near a silty/sandy bottom
Might destroy corals and other marine life

Frog Kick
The underwater equivalent of the breast-stroke kick. Thrust is provided by twisting the fins, propelling water backwards.



Modified Frog Kick
Similar to the modified flutter kick, the knees are bent, and propelled using mainly with calves and ankles. This modified frog kick is preferred by cave, wreck divers and photographers. Good practice to follow, especially when diving on sites with a sandy bottoms.
Pros
Don’t stir up silt; very little downward wash (very important advantage!)
Rest muscles used by flutter kick
Cons
Not enough when prolonged speed is needed
Can’t be used on the surface

Helicopter-turn
A more advance finning method. This method is the most useful for doing a zero-radius turn. It is designed to rotate about the horizontal plane without paddling with your hands. It is essentially a modified frog kick on one leg.
Pros
Allows you to turn on the spot!
Cons
Not much…

Backwards kick
A more advance finning technique. Fins are not meant to be used backwards, so this technique is very unglam and not very refined. The technique is a reverse of the frog kick.
Technique
1. Fins are turned out and as square to the leg as they can go.
2. The legs are then spread out and the knees bent to scoop the fins forwards with respect to your body, pulling you backwards in the water.
3. Fins are rotated sideways to the water so that they can be moved back to the starting point without pushing you forwards again and undoing all the work.
4. The scooping is done with the upper surface of the fins, bending them downwards relative to your feet.






Pros
For situations where you need to move backwards and you can’t turn (think the reverse gear in a car)
Cons
Can’t be used when you want to move forward (duh!)

Note: Finning methods can be only mastered after your horizontal trim is good. Take a look at how to improve your trim: http://www.youtube.com/watch?v=btgcJXUNCY0&feature=related
Practice makes perfect! Keep practicing!
