You may not know these things about Scuba Diving, or even if you know already, just reread it for fun.
1. "DROWNING" Most people are afraid of drowning, but drowning is a lot harder than you can imagine. The human body has a lighter mass than saltwater, saltwater is denser, so you will float more. So, if you want to be drowned, you must work hard. That's why we have to use the weigh system in Scuba Diving to help you descend. Because most people float, which is good if you like to stay at the surface to swim or do snorkeling for the whole dive, check our specialty Peak Performance Buoyancy to become a better diver by improving your buoyancy.
2. "WETSUIT" is a special suit worn by Scuba Divers. It is made from rubber materials called Neoprene. The thin layers of water between the diver's skin and Neoprene keep the diver warm and retain body heat. Wetsuit not only helps the divers avoid hypothermia and a dangerously low body temperature but also protects your skin and body against minor harm from some marine animals and rocky reefs. Moreover, a good wetsuit has to keep your body in shape, so it can help you look good in photographs.
3. "SCUBA MASK" Diving without a scuba mask could be slightly more than blind in exploring the underwater world. You will need this essential scuba diving equipment for every dive. A scuba mask allows one to see the fantastic reefs, wrecks, and other marine life through tempered glass lenses. A good scuba mask requires good vision and comfort. You have to be able to pinch your nose while you equalize easily and quickly clear water without a lot of effort.
Scuba Mask Tips: wear the mask to cover your nose as well, do not cover only your eyes.
4. "STRANGE SOUNDS UNDERWATER" Have you ever wondered why everything sounds so strange as soon as you get underwater? When you are on land, sounds travel in waves through the air until they reach your ears and vibrate your bones in the inner ears. But underwater, sound waves go straight to your ears through the water. Soundwaves move five times faster in the water than in the air. On average, 65% of your body is H2O, so your body is mainly made out of water. For this reason, underwater, you can't figure out where the sounds are coming from, the direction, and the distance. Sometimes you hear only the higher frequencies.
5. "WATER ENTRY METHOD" The five most common scuba diving entry techniques are:
-
"Giant Stride" is probably the most common way to enter deep water.
-
"Forward Roll" is best used on large bottom boats.
-
"Back Roll" is best used on smaller dive boats.
-
"Seated Entry" is handy for shallow water or quietly entering.
-
"Shore Entry Wading" walking from the shore, with or without fins.
There are many dive techniques and more details about entering the water, but no best method is defined. It is usually determined by the type of platform you are diving from, what you're most comfortable using, and the safest way determined by the conditions. There is one more way we would not recommend you to do, "Being Kicked Down" which can be done by your buddy or anyone else on the boat. This method can be harmful. Also, no deep or shallow water is recommended. Do not do this to your friends or anyone.
6. "PRESS THE BCD BUTTON" "BCD" stands for Buoyancy Control Devices. We use BCD to control our buoyancy both on the surface and underwater. Air Bladder in a BCD inflated with air from your cylinder. As you ascend, you release air to prevent air in your BCD from causing an uncontrolled or rapid ascent and vice versa. As you descend, you add air to the BCD. You need to press the inflator button when you want to come up floating. It is always the closest button to the air inlet. Pressing the inflator button adds air to the BCD. Pushing the button expecting you will go up is a lot different from the button that will send you to space. It can bring you up only on the surface. It cannot bring you any higher than that.
7. "ALIEN BLOOD" If you see your buddy bleeding green blood underwater, they are not aliens. Here is the reason why. Blood does not change color from red to emerald green at all. What changes down there is the light in the water. Different colors below 15 meters get absorbed by water at different rates. Red color disappears quicker, but blue and green colors travel longer than red underwater.
8. "THE FINS" Do you know that most fins have no left or right? Both fins are identical. It doesn't matter which fin goes on which foot. In this case, you will always find the fins' foot pocket, fin design, and blade the same for each pair of fins. So it is less customized for each foot. Refrain from wasting time figuring out if you are wearing the fins correctly to your left or right foot.
