Signals on Diving and Communication

Absolutely there is no way to talk underwater.

You can shout to make some voice but that wouldn’t be a “communication”. Creating attention and communication are not same things.

Although diving activity is such an activity that we need a serious way of communication, physical conditions are not allowing us to do that. However, divers always find a way to manage with the situation.

There are many reasons why we use our language to express the current situation. There can be an emergency or something else, which we have to reply back or acknowledge.

Silence

Nobody actually wants to break the silence during diving. You find your way in deep blue, surrounded by underwater beauties or pure blue. Most of the people are there, practically to be able to relax and calm down. So, the ways of communication should be precise, short and right to the point.

Warnings

Beauty of diving as a group brings safety. There will be always people watching your back and warning you against dangers, or checking your equipment status if they are working properly, such as checking your air pressure, deco time…etc.

Pointing

Your buddy may want to show you an interesting creature, something you have to see, or a direction you have to go. For these things, you have be able to communicate and exchange information with limited sources.

Ask for explanation

Of course, you shouldn’t proceed with every warning and instruction you have been given. Person who gives you information might be under influence of nitrogen narcosis. Person on this state can give misleading instructions. Therefore, you have to be sure and question the instructions by replying back.

Ask for immediate help

Underwater diseases and emergencies can cause the diving to end. When that time comes, we might not be able to terminate the diving on our own. On the other hand, for small problems can be solved with a little help from our buddy, we should be able to explain what problem is so they can work on that without terminating the dive unnecessarily.

Regular checks

On diving, regular checks are essential. Your instructor or your buddy checks you for your air left, sometimes for your buoyancy, navigation, and most importantly for your mental status. We have fixed gestures to ask these common questions and simple answers to reply them clearly. Because especially under this circumstances, not causing any confusion and giving manipulative respond is essential.

How to act under emergency situations

On group diving, in case of any emergency, it doesn’t mean that whole group should terminate the trip. However, since you have to follow the leader, figuring out when to proceed together or when to wait for instructions are essential.

Let’s see what they are;

  1. “Okay”

Before diving, every diver should make buddy check to each other.
We start with this signal from the beginning.

You will be asked with this gesture. If everything is satisfactory, you will reply back as same.

When you are waterborne, especially when you are jumping from a boat, first this to do is that you have to confirm for status. If everything is ok, this is the move you should do:

  1. “Emergency, Help”

In case of any problem, get your mask up to your forehead and hit your hand to create attention by splashing water.

  1. “Go down”

Meanwhile every team members are in position, instructor checks if everyone is “ok” and gets confirmation to proceed. After group can “go down” with instructor’s signal:

  1. “Come Here”

When divers in position, instructor can give the follow order to proceed after him. Also, for calling a person to a specific position, this signal can be used.

  1. “Stay (Stop)”

Moves should be clear and precise. To be able to stop a person , we need to give this signal clearly.

  1. “How much air left?”

It is very important question on diving. You have to check your air status regularly and report it to your instructor or your buddy. Your pair will align estimated time to spend underwater, according to your air left. Time to time your instructor can ask your air status with this signal.

  1. “Reserve, low air”

Low air defines that you have approximately 50 bar or less in your air bottles. In situation which you have low air in your bottles, you have to give this signal and inform them.

  1. “Ascent”

Don’t mix with exit, it is only a warning that you need to ascent a bit, preventing yourself going deeper, or hit to the bottom and disturb sea bed or getting apart from the leader. On group diving, you shouldn’t be deeper than the leader. Your instructor time to time might warn you to ascent a bit.

  1. “Something is wrong”

Divers can find themselves under some uncomfortable situations. Some of them can be fixed by the diver within sort notice. However, some requires help to overcome. For that, diver needs to ask for help. About the problem, diver need to be very precise.

There is a problem, but where?

This hand gesture will follow the indication of the source of the problem.

  • Problem, in the ear (point out the ear)
  • Problem, in the leg (like a cramp, or another problem, just point out the leg)
  • Problem, breathing (point the out the chest)
  1. “Buddy Up”

It is very important that buddies should stay with each other. Once group starts separating, instructor can’t control the group order. If the instructor sees that buddies getting separated, he might warn by pointing them out and ask for them to be stick together.

In the next article, we will continue with the most important ones during trainings and how to indicate numbers, express air pressure quantity, some common misunderstandings and how to prevent them, also how to act during night dives.

How to Dive?

            As soon as reaching 10 years old, everyone is free to dive, as long as they are healthy and fit enough to dive. Either you can “meet” with this world with a quick “discover” dive, without any certification, or you can “free dive” with one breath, letting yourself free from any equipment, or feel free from pressure of losing your breath and get the utmost pleasure with scuba diving. Because believe me, you will see astonishing things which will take your breath away, more than once!

Types of Diving

Discovery Dive

            This type is, if only you are a non-diver but you want to see what is going on underwater. It is clear that you can’t just take the equipment and go directly. For this, you need to take necessary minimum briefing for essential points of diving with a guide.

            An experienced instructor as guide leads discovery dives up to 5 meters. Because, in case of any unexpected circumstance, this is the safest depth to end the dive and to proceed to the surface immediately. Since discovery dives are for uncertified and inexperienced people, caution is crucial.

Steps of safe discovery dive;

-Briefing about important rules

That is why you need be trained properly to get awareness for the basic physical, mental and scientific requirements.

Free Diving

            Comes from its name, it makes you free from some equipment, as long as you have strong lungs to keep you below the surface. That is why, free divers should train themselves with strict mental and physical therapy to feel ready for very deep dives, which is even sometimes dangerous for scuba divers. Once you have proper readiness, you will free from everything, when you are underwater.

Technical Diving

            After 40 meters, recreational diving ends. Requirements for diving, equipment to be used, air you breath and mental readiness change below this limit. That is why; this type of diving is only suitable for experienced divers. Divers go down below the limits because they want to discover wrecks, biological researches, and sometimes for underwater repair jobs of the oil platforms… etc.

Types of Certificates for Divers (other than instructors)

            Although there are many types of diving certification standards in the world, international and well-known types are CMASS, SSI and PADI. All certifications are basically same. For each certification you need to prove both theoretical and practical experiences required for each types.

CMASS

            Expansion of CMASS is “Confederation Mondiale Des Activites Subaquatiques” means World Underwater Federation built on 1959 in Monaco. As diver, other than instructors, there are 3 levels available.

            1* Open Water Diver – Diving up to 18 meters with an accompany of an instructor. After completing 25 dives, you have right to train for 2 Stars. These trainings help you to understand basics of the equipment you use, diving risks and how to eliminate them and take the proper actions under simple emergency situations.

            2* Open Water Diver – Diving up to 30 meters which is considered as deep dive and 40 meters with deep water diver specialty. Two 2* divers can dive together without any supervision of another instructor. They are expected to have basic awareness on rescue techniques, navigation and perfection on buoyancy.

            3* Open Water Diver – Diving up to 56 meters, however utmost caution must be considered because of potential hazards start after sportive limits. 3* divers are considered as assistants who are expected to be future instructors. That is why they should reach their full potential on buoyancy techniques, navigation and rescue techniques, during their 3* period before staring their level upgrade courses.

SSI

            Scuba Schools International was built on 1970 by Bob Clack. These days, it is considered as one of the best certification system in the diving community.

Why Should You Dive?

            Many people want to dive but only few people have this courage to follow this desire. Mostly, many concerns about safety, phobias, non-suitable economical conditions stop people pursuing their dreams.

            Usually travellers consider whole world only consist of things from above the surface where you can see with naked eyes. However, in the other %80 of this blue sphere, there is amazing and astonishing side of our known world, which we can discover endlessly behind the diving mask. Water creates its own environment, and it is way different than air does.

It is totally safe,

            Never get stuck with stereotypes about diving. Ask someone who actually dives. All of them will always say same thing; “It is the safest sport in the world!”

            Like hammerhead sharks, their look is the scariest one but they are the calmest ones among many animals. You would know this fact better if you were a diver. So, this is another reason why you should never believe in things, without experiencing that, at first hand.

            Of course, unless you follow the rules as it suppose to be without extending them by your own heard… There are very simple facts and rules to keep in mind. As long as you follow them strictly, every training and equipment with you will be your safeguards during your experience underwater.

-Swimming in an aquarium with ravishing colors,

            Just consider the colors you have met in world and get read to see more underwater. All around the world, there are thousands of dive sites and each of them better than the other. Some places, colorful fishes and reefs with corals are more, then the water density around, which makes the dive site like a carnival. Sometimes only thing you should do is hit the fins and watch the beauty flows around you. Of course, different colors are not the only thing you will face. Some of them will be chatoyant or transparent, which makes you lose your mind because you can’t believe if this kind of creature can be alive!

            Shapes of their body, quantity of their legs, eyes, tentacles and harmony between them will impress you and it will definitely change the way to see the world you have been living so long.

-Feeling like you are in space,

            Since you were born, probably you haven’t experience how it feels not being exposed to gravity, ever. Well, you can go to some expensive simulators or you can try to be an astronaut and NASA will give you this experience eventually. Whereas, you can leave yourself to the blue sea and you can conquer the gravity with your equipment. You will learn how to control the air with you like an Airbender. Believe me, coolest thing ever!

-Silence,

            How many of us are able to find the perfect silence in the city atmosphere? Sometimes, you just want to be alone, just to relax, keep your precious brain away from all those tiring and unnecessary voice disturbing you on your work, in your house, sometimes even between your friends. This very hard thing to find is not that hard just after couple of centimeters below the surface. Such a silence that even your thoughts can start being very noisy after some point. You can let things slide and enjoy the underwater therapy on your consciousness. Let the blue miracle distract you for a while, away from everything, like changing the dimension…

-Alone but together,

            It is a matter of being a member of a team of trust. Your diving buddy is also your extra air tank, if you have cramp in your body, she/he will be the one who’s going to be with you and help you. If you get lost, they are the ones who will find you. Consider there is another a pair of eyes looking after you.

            On the big teams with group of buddies with a leader in front and securities behind, you always feel safe. Divers are one of the most attentive sportsmen who have high sense of responsibility both on themselves and on their friends. Because they know that, as much as they take care of themselves, they make a contribution to sustain the group harmony and they always watch over not only their buddies but other buddies in the group. Divers always think bigger, away from selfishness.

-Healthy,

            For every sportive activity, physical fitness is essential to be able to continue doing that sport perfectly. At the beginning, you are required to align your buoyancy similar to the zero gravity environments, which eliminates the pressure on your spine and your joints. This process reduces chronic back and joint pains. Beside of this, every time you hit the fins, your muscles and tendons stretch effectively, because there is no body weight pressure stresses them. On the other hand, edema in your body drains under water pressure and cleans your body and relives pressure on your organs and joints. Of course, very important, this process makes you lose a lot of water. So, you have to put necessary water for your kidneys back by drinking good quantity of water.

-Exploring new spaces

            No matter how much you dive in one point, dive sites are changing and evolving environments for each season and also within the time. Each time you dive, you will discover new things and find new diversity to witness. That is why, you will never get bored even if you dive at the same point frequently.

Complete travels, under and above the water.

            During your travels, you will have chance to see whole beauties of that place, surrounded by both air and clear waters… Many waterside countries have diving points available. And in case of natural beauties, some of them have the ones even better than they have in the shore side. Leaving that country without seeing its underwater affluences might be a huge loss in your experience.

Lifetime passion

            Because it includes sport, socializing and travel, after some time, you can find yourself planning your life schedule for your new diving trips, saving money for LiveAboard diving trip weeks. From the equipment which divers use, to the biological awareness, which you will develop in your world of interest, diving world will improve your life and you will feel the transformation it in your blood.
