This helps you to get a neutral buoyancy underwater, therefore, they help you to ascend and descend the waters efficiently. A weight belt should also be worn that helps in buoyancy. Diving cylinders are another important equipment, without which scuba diving is a 'no go'. Regulators, on the other hand, help let the air out in a controlled fashion. With a good mask and snorkel, you are ready for your first dive. You can choose to carry a knife or shears, to cut fishing nets or to pry rocks. After all the equipment is gathered, perform a final check. Go with a good mindset, have a positive attitude and if something goes wrong, don't panic! Your dive operator will be around to help you out.
