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.
Can You Vomit While Scuba Diving?
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.
What Happens If You Sneeze While Scuba Diving?
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.
Why Should You Rinse The Inside Of Your Buoyancy Control Device?
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.
How Can I Improve My Buoyancy Control?
The best way to improve buoyancy control is to use your buoyancy control device effectively, master your breathing and perfect your weights. Maintaining a better body position and fine tuning your finning technique also helps, but one of the best ways to improve buoyancy control is to dive more.
How Many Dives On A Liveaboard
The total number of dives on a liveaboard range from four dives in total for the entire liveaboard trip up to 68 dives during the trip for longer itineraries. This can mean you dive up to 4-5 times per day on some liveaboards, but how many times you dive up to their maximum is entirely your choice.
