ghten out for an underwater swim (Counsilman and Drinkwater 29). Another dive is the Feet First dive. Tread water over the spot where the dive is to be made. Raise the body out of the water with a strong kick and a downward push with the hands and arms. Then straighten legs, point toes, and raise the arms overhead. The weight of the upper body and the arms will force the entire body under the surface. When the downward motion stops, bend at the hips and, with and underwater pike, either continue the dive headfirst or level off to swim (Counsilman and Drinkwater 29). The mask, the snorkel, and the fins are three of the most important tools in diving. Occasionally, water may seep into the mask, or the mask may become dislodged and flooded while the diver is under the surface. Sometimes a diver can simply surface when the mask becomes flooded, but it may be necessary to clear the mask before surfacing in order to have visibility during the ascent. Grasp the mask Korell 4 and pull it away from the face to allow the mask to flood. Roll the head to one side so that the face plate is turned to the surface. Hold the uppermost side of the mask firmly against the face, and exhale into the mask through the nose. The air trapped in the mask will fill the space and force the water out under the bottom edge. Some divers prefer to clear the mask by holding it firmly against the forehead and tilting the head back until they are looking up at the surface before blowing into it. Common errors are failing to tilt the mask toward the surface, pressing the top edge so tightly against the face that the mask is pulled away from other parts of the face, and allowing air to escape under the top edge of the mask by failing to hold the mask firmly in place (Counsilman and Drinkwater 31-33). The snorkel is a critical tool for breathing underwater. Most divers attach the snorkel to the mask strap so it cannot be easily lost underwater. First, slip the mouthpiece in...
