As the scuba-gear store Underwater Kinetics reports in a blog submit on the subject, there’s a “dad joke”answer to this query: Scuba divers fall backwards as a result of in the event that they fell ahead, they’d end up in the boat! But jokes apart, there are a couple of causes why it is sensible for scuba divers to take the plunge backward in what’s known as the “back roll entry.”
The back roll entry is helping diving gear keep in position.
According to Underwater Kinetics, the again roll entry is helping a diver keep their gauges and regulator stay in place. If they had been to dive in face-first, the affect of the water would possibly knock the equipment misplaced or even unfastened. “By diving backwards, assuming you do it accurately, you ensure that you don’t enter the water without equipment,” the retailer notes.

It additionally eases a diver’s entry into the water.
The again roll entry is also easier on the body, especially as a result of scuba divers are laden with numerous further weight, especially with the oxygen tank on their backs. By diving in back-first, you’re letting the tank lead the way and avoiding conceivable harm.
“The impact of a feet-first dive is difficult on your joints and will reason an harm when you don’t hit the water appropriately,” A-1 Scuba & Travel Aquatic Center of Littleton, Colo., explains in a weblog post. “Similarly, a headfirst dive may cause an harm from the impact or from loose equipment.”

And it helps to keep smaller boats strong on the water.
Another sensible reason for the back roll entry: It assists in keeping smaller boats from rolling side to side as divers stand on the gunwale, the highest fringe of the hull. “While those boats can have a low heart of gravity, a couple of divers status at the gunwale will shake issues up on board,” Underwater Kinetics tells readers. “By getting into the water with a backwards fall, you minimize this rocking motion for everybody else on board.”

There are other entry ways, too.
Scuba divers don’t at all times dive in backward with the back roll entry, then again. You might see divers taking the use of the “massive stride” manner on better boats and yachts specifically outfitted for scuba diving, which have stable dive platforms. “Keep a hand to your regulator and mask as you get ready for an enormous stride,” A-1 Scuba & Travel advises. “Check the water for any hindrances sooner than stepping out into the water and ensure your doorstep is big enough to keep away from hitting the aspect of the boat with your tank.”
Then there’s the “seated entry” approach, which is comes to sitting at the gunwale. “Put your legs over the facet and cling directly to the facet of the boat with your fingers,” says A-1. “Turn around, so that you’re facing the boat as you raise your self over the brink.”
Happy diving, other folks!
