Scuba diving is one of the most daring sports that people want to do once in their life.

For many, it helps to explore the natural and magnificent world in unforgettable locations, underwater. It is a great way to free one's stress.

Why do scuba divers dive backwards? This question must have hit your mind at least once whenever you see a scuba diver performing the back roll in a movie, series, or real life. Although scuba diving is a fun activity, sometimes it becomes dangerous without proper safety gear and diving practices. Various training centers offer proper dive gear for all the people with all levels of diving experience.

There are numerous ways to enter the water when you perform diving. However, one of the best and most common is when scuba divers dive backwards into the water. This entry method is associated with an old-age joke! So why do scuba divers dive backwards? The technique is called backward roll and is one of the safest techniques to enter the water. It is mainly because jumping feet first or heads first cause harm to the body. In this technique, scuba divers dive backwards with all scuba gear on. A person sits on the edge of the boat facing the boat and then makes a backward jump.

It is an easy practice but takes time to perfect. It is important to make sure that you always wear gear before you are ready to dive. These gears and suits protect the divers from the pressure in the depths of the ocean. Also, check if the gear is working properly or not! If not then replace the gear - definitely do not go diving wearing faulty gear. Plus, confirm the batteries of the dive computer. It is best to go through the complete dive equipment guide before you ready yourself for diving. After that, hold your regulator with one hand and use your fingers to steady your mask. Put your left hand on the loose hoses at your sides. Check if the water area is clear around you. Now, tuck your chin towards your chest and then carefully fall back into the water. This method is one of the easiest ways to enter the water. Sharks also do not attack divers since divers are usually very deep in the water making it clear for the sharks to see.

Backward roll conditions for scuba diving: In this method, a person is going to fall backwards into the water. This method is most useful when there are 4 ft (1.2 m) or more of space between the water and the surface of the boat.

Reasons Why Scuba Divers Dive Backward

Why do scuba divers dive backward might be something people with no scuba diving experience wonder. Scuba divers mostly choose the backward roll as a method of entering the water. There are many reasons behind it. When people dive backwards into the water, they usually protect these three things from any injury or damage: boat, body, and gear. It does not matter whether you are on a larger boat or a smaller boat, if you are entering the water by jumping head first or feet first, it can lead to the risk of an injury. The feet first dive can cause injury, especially to your joints if you do not hit the water carefully. Furthermore, a headfirst dive can also result in an injury if the impact is high or from loose gear too.

A backward roll or back roll restricts the boat from an excessive swing. Any other type of dive usually results in shaking the boat unsteadily, which may cause other divers falling from the boat. It could lead to dive gear damage, especially the mask and fins. Therefore, this type of entering technique helps to control the equipment of the diver. It is preferable to preserve your diving equipment and maintain control of your mask, pipes, and fins while facing away from the water. Scuba divers who enter the water the wrong way up frequently wind up with water in their masks. Therefore, falling backward into the water is more comfortable for your body as it could also be harmful to your body if you fall from a few feet. Entering the water headfirst while carrying a large scuba tank on your back might have a number of negative effects. As the mask meets the surface, it may cause a painful blow to the face. As a result, it is by no means an acceptable entry method since scuba divers tumble backward. Divers also rise up slowly because rapid ascents can result in decompression sickness. A diver's body absorbs nitrogen gas during a dive. Following Boyle's Law, the nitrogen gas compresses due to water pressure and progressively saturates the bodily tissues.

Different Techniques To Enter

There are about four best entry methods in scuba diving. All of them have different techniques, merits, and demerits. Although most divers like to enter through the back roll or backward roll, scuba divers choose their entry methods according to their comfort. The other three entry methods include the giant stride, the seated entry, and the shore entry.

The giant stride: On a dive boat, there is the usage of a sturdy platform. If you can stand on the edge of the platform with your fins over the edge, this may be the best approach for you. Hold your mask and regulator in place as you prepare for a long stride. Make sure there is enough room for you to avoid striking the side of the boat with your hefty tank.

Seated entry: This way to enter is best if you have a smaller dive boat or do not have a stable platform near the surface. It is a safe option, just double check your equipment, such as fins, mask, and regulator, and then sit on the edge of the boat. Place your legs and feet over the side of the boat. Then turn around on the opposite side so that you face the dive boat as you lift yourself over the edge. Make sure you are clear not to hit the tank against the side of the boat as it can cause damage to it.

Shore entry: This is the trickiest dive and is usually carried out at a resort. It includes walking into the water of the sea but requires skill to do with a regulator and hefty scuba tank. To perform this, walk backward slowly into the water. Make sure your tank faces the water in order to avoid falling forward.

Of all the ways available, both the seated entry and the giant stride entry are the most well-known methods.

Divers fall backward to enter the water for stabilizing the boat.

Which entering technique is the best?

Every method has its own advantage and disadvantages and people select their choice of way of entry based on their comfort. Every diver has their own preference related to the entry method.

The backward roll entry is the best choice for the scuba divers who are on a small boat, such as a hard inflatable boat as this type of small boat probably has a small platform which makes it difficult to stand on the boat and enter the water. It is also arduous to enter with smaller boats as they shake vigorously when a diver makes an exit from them. It is also best for the disabled or old divers. It is always suggested when you are diving from a small boat to enter the water by the back roll as it keeps the boat more stable. This type of dive is safe when your boat does not possess a firm platform as it does not need balance.

Advantages Of Backward Roll

The backward roll has its own perks. Some of the advantages include:

Maintaining a seated position lowers the center of gravity of the platform of the boat and prevents it from shaking unnecessarily during diving.

The back roll restricts you from a belly-flop accident when entering the water, which may cause your gear to be misplaced and fill the mask with water. A belly-flop can also cause your mask to hit your face painfully.

The back roll technique requires less exercise, which is not the easiest thing to do when wearing scuba equipment of 30 lb (13.6 kg).

Entering into the water in a diving style is much more difficult than doing a back roll in a diving suit.

It is also easier to learn than other entering techniques.
