The pike dive is used when you're swimming at the surface. Use the following procedure when performing the pike dive.

1. As you are swimming, bend your waist until your upper body points straight down into the water.
2. Quickly lift your legs straight up until your entire body is straightened. The weight of your legs will push your body below the surface.
3. Begin kicking as soon as your fins enter the water. Remember to equalize your ears as you descend.
