Learn to Scuba Dive

It is possible for a person to dive to a depth of 50 meters (164 feet) with the appropriate training, equipment, and safety measures in place. Diving to this depth is considered a deep dive and typically requires advanced diving certification and experience.

If you vomit while scuba diving, keep your regulator in and vomit through the regulator exhaust vents. Unless you are vomiting huge chunks of food, it should flow out the exhaust vents without a problem.

If you sneeze while scuba diving this could disrupt your mask and create water leaks, or you could dislodge your regulator at the same time as momentarily affecting your buoyancy. During the sneeze you should hold on to your mask and regulator to minimise the affect of the sneeze while scuba diving.

A scuba diving negative entry means you enter the water negatively buoyant, so you have no air in your BCD to allow a fast descent. Negative buoyant entries are often done as a backward roll from a RIB or Zodiac, but can be done using any entry technique including a stride entry from a hard boat.

You should rinse the inside of your buoyancy control device to remove saltwater or chlorine depending on your most recent diving activity, to clean out any sediments and to prevent bacterial growth. Proper maintenance of your BCD by regularly rinsing the inside with water will help your BCD last.
