Question

why do scoba divers dive backwards?

Answer 1

1. When you’re facing away from the water at first impact, you’re better able to shield your equipment and keep a hold of your facemask and hoses. Divers who try entering the other way usually end up with water in their mask, if they can keep their mask on that is. Suffice to say, it only takes one attempt at a forward roll to realize it’s not a good idea.

2. Even if you’re only falling from a few feet, water can be a pretty unforgiving element. Falling forward with a heavy tank on your back can be an uncomfortable experience, to put it lightly. You may also get a painful smack in the face from your mask as it collides with the surface.

3. The backward roll is the best option when you’re in a small boat like an RIB (rigid inflatable boat). These smaller boats may have a low or less-than-sturdy gunwale, preventing you from standing on top and stepping into the water. Another consideration for these smaller boats is the impact you can have stepping off of them. If your exit from the gunwale is going to cause the boat to rock dramatically, the backward roll minimizes the effect..
