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.
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.
Is Scuba Diving Hard On Your Body?
Recreational scuba diving can have significant effects on the body including increased blood pressure, but this shouldn’t pose a risk if you’re fit and healthy. If you have heart disease, high blood pressure, angina, diabetes or if you’ve suffered a stroke consult your doctor before diving.
Do You Need To Be Strong To Scuba Dive?
You don’t need to be strong to scuba dive as long as you are generally fit and healthy and able to lift the heavy weight of your scuba equipment out of water.

Do Wetsuits Protect From Stingrays?
A wetsuit will not protect you from the barb of a stingray, as it will go straight through the neoprene of the wetsuit and into your skin. But stingrays very rarely attack people unless they are provoked or threatened, so wetsuit or no wetsuit, you are unlikely to be attacked by a stingray.
Do Wetsuits Protect From Sun Ultra Violet Rays?
Can you get a sunburn through a wetsuit? Wetsuits do protect you from the sun as the wetsuit’s neoprene creates a layer and a barrier over your skin to stop the sun’s harmful ultra violet light rays from damaging your skin, as well as keeping you warm. To get complete protection from the sun using a wetsuit it needs to be a full wetsuit.
