Divers enter the water in a number of ways, but one of the most common is called backward roll entry, back entry or backroll. This happens when the diver sits on the side of a zodiac boat or a small dingy holds onto their regulator mouthpiece and just allows gravity to move them underwater.
This is the safest and most common method if you are diving from a big ship, which is to step forward (also known as a giant stride). In this method, you can use your regulator and mask as a ‘Stride’ that would be held with one hand. And with your hoses against your body to make sure they stay in place as you hit the water.
If you dive from a small boat where you can’t stand due to lack of space, then rolling in backward will be the safest way to make sure that your mask and regulator stays in place and that your hoses do not risk getting stuck anywhere.
Basics of the Backward Roll
If you are diving from a smaller dinghy or rigid-hulled inflatable boat, then standing on the outer edge of the boat can cause the boat to rock from side to side and become dangerously unbalanced. Sitting on the outer side edge of the cruise keeps the boat’s center of gravity low, and prevents the craft from becoming unbalanced.
Are There Are Any Dangers To The Backward Roll Entrance?
While the back roll entry is practiced because it’s a safe way of entering the water but there are always some risks attached to any way of entry because you are wearing extremely heavy equipment on a relatively unstable boat after all. The main danger of backward roll is hitting someone as soon as you enter. Obviously, you can reduce the dangers of this by checking the water is clear before you roll, but there is always a slim chance that something has come in your way as you enter.
How To Do A Back Roll?
Backroll entry by scuba divers is usually done by sitting on the side of a small boat. The time you are ready to make your entry, you should be fully prepared, including everything such as your mask, wings, and regulator.
To perform your back roll entry you will then do as follows:
Ensure you are wearing your mask and your regulator in your mouth. Make sure your BCD is filled with air so you float when you hit the water if you’re performing a normal positive buoyancy entry. Your mask should firmly fit your face.
Now take a look behind you to ensure the area you’re rolling into is clear of people and debris.
Place your left-hand palm over the regulator to check it does not come out during entry, and your fingers over your mask to be sure it doesn’t come off – some people use their right hand for this, it’s up to you.Use your right or left hand with which you are free to hold and secure any other loose equipment you may have – such as your gauges, or an underwater camera.
Take one last quick glance behind you to make sure the area is still clear. Slowly roll backward, letting the weight of your body and equipment do most of the work – you don’t need to be using lots of force to propel yourself backward. Once you have entered the water, floated to the surface, and got your bearings, give the boat the big OK sign with your arm.
Reason Of Why Scuba Divers Dive Backwards
Scuba divers dive backward to ensure that they do not shatter their masks, or break any of their other equipment, such as their regulator. Diving backward is also required on small boats, where it’s too small or not stable enough to perform a giant stride.
When going to a diving site on a small boat or even drenched an inflatable you will almost certainly perform a backward roll to enter the water. The main reason for this is the small space and stability of the boat. Trying to get up with all your heavy equipment is tough enough on a large stationary boat, let alone on a small boat that is moving forward and backward.
You also have to think about the safety of your other divers, you are going to stand in a small space with a heavy metal cylinder on your back; You can easily kill someone, or even fall on them due to poor stability.
Diver safety is extremely important whenever you are engaged in any type of diving. While it may not look like it at first glance, falling backward is a very safe way to enter the water. A standard diving cylinder weighs around 30 – 35 pounds, so you don’t really want to shift it and hit you with the back of the head. This can happen when you jumped in the head.
Also, when you enter the water at the back, any underwater obstruction will hit the tank instead of your body. Clearly, you should know what happens below the surface whenever you dive, but sometimes accidents happen. If anything goes wrong during the backward entry, you will have the advantage of facing the water instead of face down. Another important aspect of diving safety is a good dive float and flag to be visible to you.
Scuba Diving Gear:
Scuba diving equipment allows you to travel to the underwater world to breathe, see and move comfortably while still under the surface. The gear helps you get somewhat aquatic by being land-dwelling – if only for a short while. It has a mask that helps to see clearly. The regular and tank help to get required air whereas the features let you swim easily. Being a beginner scuba diver or an experienced diver looking for new equipment, you will find useful tips and suggestions in this section. Just remember to consider three crucial things when you choose a gear i.e. comfort, fit, and suitability. But you don’t need to forgo good looks so you can make a decent color combination.
Other Entry Techniques
The Seated Entry
As long as you have a platform that is close to the surface you can sit on the boat’s edge with your feet fully on the shore. You can then lift your body to the side with both arms and then bend so that you can face the boat. This method is ideal if you have limited space entry or unstable surface.
The Giant Stride
When you have a stationary platform on a dive boat, you can stand on the edge of the platform with your wings and hang on the shore. Check on your mask and regulator for safety. And do one final check that the water is clean before taking a big step in the water – enough to avoid accidentally leaving your tank on the side of the boat.
