8. Turn back to the boat or platform and signal to the divemaster that you are okay. Do not signal that you are okay until you know that you are. 9. Swim clear of the entry area so the next diver can enter the water. The key to doing a good giant-stride entry is to be in the stepping position (one leg behind you and the trunk of your body upright) as you enter the water. Then, as you go under water, bring your legs together to propel yourself back to the surface. A variation to this entry involves putting your feet together before you hit the water. This will take you deeper, and can be used in special cases where you do not wish to resurface immediately. This variation can also place less strain on the legs if you enter from a height greater than about 2 meters (6 feet). Back Roll Entry You use the back roll entry when a boat is so small that if you stood to enter the water you could injure yourself by falling or fall out of the boat (figure 3-31). This entry is also used if you are entering the water from the side of a boat with high gunwales. The steps to a back roll entry are: 1. Have your fins on and your mask and regulator in place. 2. Seat yourself with your back facing the water and your rear end partially over the edge. 3. Look behind you at the water below to ensure that there are no obstacles or divers below you. Chapter 3- Diving Skills 4. Hold your mask and regulator with one hand and your weight belt and any loose items with your other hand and arm. 5. Lift your legs and let the weight of your cylinder roll you into the water. Your body should be in an “L” shape with your legs straight. Maintain an “L” shape as you are going into the water, or tuck your legs to your chest. 6. As you go under water, swim away from the boat or platform and back to the surface. 7. Be sure to turn back to the boat or platform and signal to the divemaster that you are okay, if appropriate. 8. Swim clear of the entry area so the next diver can enter the water, if appropriate. You might experience some dizziness as you roll into the water. This results from upending or agitating the fluids in your inner ears as you turn. You will reorient in a few seconds. Also, be sure to recheck your mask strap, because it has a tendency to slip off your head during this type of entry. Seated Side Entry You can use the seated side entry from the side of a swimming pool, a ledge at water level in a quarry, or from a boat dock (figure 3-32). This is a good entry whenever you can sit at the water’s edge, make your final preparations, and then lower yourself into the water. The steps for a seated side entry are: 1. Sit at the edge of the water with your legs in the water. Diving Skills 63 FIGURE 3-31. YOU DO A BACK ROLL ENTRY FROM A SMALL BOAT. FIGURE 3-32. THE SEATED SIDE ENTRY IS EASY AND CONTROLLED.
