Diving Technique

Before starting a dive, carry out all the preliminary preparations required for the type of scuba you are using. The following is the minimum equipment for safe scuba diving: swim trunks or protective suit (with distinctive band of coloring), life preserver, belt and knife, swim fins, face mask, scuba. Two highly desirable pieces of equipment are a wristwatch and a depth gage. Other accessories that may be necessary are a weight belt, wrist compass and a buddy line.

Enter the water feetfirst, climbing down a ladder or easing over the side of the boat. Do not jump in. Stop at the surface and make the proper surface check for the type of scuba you are using. Check the scuba for satisfactory operation. Check your buddy’s scuba for leaks of any sort, and have him check yours. Check your face mask for proper seal to minimize flooding. Adjust your buoyancy.

Orient yourself with available natural aids such as sunlight, current, or landmarks. If you are planning to swim to a specific point, check the compass bearing of that point. When you are sure that you and your buddy are ready, check the time and start the dive. Make a slow, orderly descent.

Do not try to race your buddy down or outrun him. Swim or pull yourself headfirst down the descending line. Be sure that the pressure is equalizing in the ears and sinuses. Stop the descent if pain develops; level off or ascend slightly until the pressure equalizes. Discontinue the dive if the pressure does not equalize after several tries.
